Laser exposure Laser exposure direction direction The LS series performs measurements by emitting a parallel laser beam and receiving the reflected light. During measurement, ensure that the laser beam and reflected light is not blocked by the target object. Before using the product, check that stray light, which is reflected by a wall or by highly reflective objects, does not have an effect on the measurements.

Page 83: Camera Settings
Camera Settings 5.4 Camera Settings 5.4.1 Camera Mode Select the camera mode. For "Hi-res" mode and "Hi-spd" mode, one measurement is performed for each image. For "HDR" mode and "NR" mode, two images are taken by the camera for each trigger, and then one measurement is performed for these two images.
Page 84 Camera Settings Operation of the "HDR" camera mode Workpieces where HDR is effective Use this mode when measuring workpieces that have parts whose reflective status vary greatly. The following example uses a workpiece that has a white and a black part, as shown in the figure to the right. To measure this workpiece, it is necessary to acquire a profile like that shown below.
Page 85 Camera Settings Operation in "HDR" camera mode In "HDR" mode, the brightness from images captured at fast shutter speeds is amplified. The amplification rate is determined by the ratio of the shutter speeds of the two images. (Example: If the shutter speeds are 1000 μs and 4000 μs, the amplification rate will be 4000/1000 = ×4.) During amplification, areas where the light level is low will be eliminated in advance as noise.
Page 86 Camera Settings Camera mode: "NR" In "NR" (Noise Reduction) camera mode, two images are taken: one when the laser is on and one when the laser is off. Measurement is performed on the difference of these two images. Because the image taken when the laser is off can be canceled, this function is effective in situations where light other than that from the laser—such as noise—has an effect on the measurement.
Page 87: Image Brightness (Shutter Time And Gain)
Camera Settings 5.4.2 Image Brightness (Shutter Time and Gain) Use shutter time and gain to adjust the camera screen brightness. With “Auto adjust”, the shutter speed will be adjusted to the optimum value. Shutter Set the camera shutter time. Set this value in steps of 5 μs. The longer the shutter time, the brighter the images that can be taken.
Page 88: Camera Range
Camera Settings 5.4.3 Camera Range Set the camera Range. The narrower you set the camera range, the shorter the imaging time and the sampling period become. The default value is the entire camera range. (Sampling period: 5 ms) Purpose of narrowing the camera range Narrowing the camera range has advantages such as those shown below.
Page 89: Received Light Waveform And Measurements
Camera Settings 5.4.4 Received Light Waveform and Measurements The heights of all the parts where the laser strikes the target are measured from the waveform. The waveform is a vertical graph of the reflected light of the laser. The following two settings are related to the recognition of the received light waveform. Normally you do not have to change these settings.
Page 90: Profile Settings
Profile Settings 5.5 Profile Settings 5.5.1 Profile Extraction Settings Target Select the measurement target from "Normal," "Gap," and "Semi-trans." "Normal” is standard. Use this setting to specify what parts of the received light waveform to use as measurement data. a) Normal The peak position of the received light waveform will be Reject level measured.
Page 91 Profile Settings c) Semi-trans Use this setting when measuring semi-transparent objects such as resin or erasers where the light enters the workpiece and causes Measured internal reflections. value With semi-transparent workpieces, the waveform profile is not stable, so the "Reject level" setting is ignored, and the center is calculated from the entire waveform.
Page 92: Save Master
Profile Settings 5.5.2 Save Master Register the acquired profile as the master image. The correction functions are set with the registered master image as the reference. You can save one master image for each bank. Tips When you change the reference coordinates for the height, position, or tilt correction and when you change the correction procedure, you have to register the master image again.
Page 93: Profile Correction
When the target's position is shifted during measurement, you can correct the position and height of the area. With the LS series, you can correct the height, position, and tilt. Do not use the correction functions when absolute positions are necessary such as for web guide control.
Page 94 Profile Settings H correct Sets the threshold. If the profile exceeds the threshold, the waveform will be moved horizontally to the reference position. Set the reference height. Set the reference height, corresponding to the master image, where correction will be performed. Area The position farthest to the right or left that crosses this height will be the correction reference position.
Page 95 Profile Settings V correct Sets the reference position. The height is adjusted so that it is equal to the height of this position. Set the reference position. Set the reference position, corresponding to the master image, at which correction will be performed. The height will be corrected so that it becomes the same as that of the measured value at this position.
Page 96 Profile Settings Correct method Sets whether to use position and height corrections and the order to use these corrections in. ● -: Correction will not be performed. ● →: Position correction (left side) will be performed. ● ←: Position correction (right side) will be performed. ●...
Page 97 Profile Settings Tilt correct Corrects the installation tilt and the tilt of the measurement target object. The profile tilt will be corrected so that the height correction reference position and the tilt correction reference position become level with each other. If an alarm occurs in either of the reference positions, the tilt correction will not be performed.
Page 98: Area Settings
Area Settings 5.6 Area Settings The LS series sets "areas" within the measurement range, and then performs measurements on these areas. You can specify up to four areas. 5.6.1 Measurement Areas Sets the positions and sizes of the areas within the camera area.

Page 100 Area Settings Width The largest distance from the rightmost point to the leftmost point that cross the center of the area's height is output. Use this function when you want to find the widths of protrusions and gaps. Tips The points that are detected by the width function are the positions that are detected by "Edge pos." P pos The position of the highest measured value within the area is output.

Output Settings 5.8.4 Offset/Offset Value When offset input is received, values are added to or subtracted from the current display value so that it becomes the value set with "Offset value." The offset value can be set for each output. When the offset operation is executed, values are added to or subtracted from the measured value of (1) the area that the output is referencing or (2) a calculation.

Common Settings 5.9 Common Settings 5.9.1 Banks The LS series stores measurement conditions in "banks." You can switch between banks according to the details to measure. You can use the sensor or communication to switch between banks. Bank switch ● In/Para You can use the sensor screen and input terminals to switch between banks.
Page 113: Axis Dir
Common Settings 5.9.3 Axis dir Set the direction in which to increase and decrease the height direction measured value. Select "Near+" (the measured value will increase toward the side near to the sensor head) or "Far+" (the measured value will increase toward the side far from the sensor head). In both situations, the origin is the center of the measurement range (at 100 mm).

Page 122 Storage Data Acquisition Method 0x03E8 (hexadecimal) = 1000 (decimal), so it indicates that there are 1000 storage items of measured values and profiles (cumulative). Acquiring measured value storage data The measured value storage results are aligned starting from the address that was acquired previously. (32 bytes per data item) 253 words (506 bytes) of data can be acquired at one time, so data acquisition needs to be divided between multiple executions when the number of measured value storages is 16 or greater.
