Note that "filter driver" filters out all packages that are not GigE on the hardware level, so the camera will work much faster than without the filter.

For compression after the measurement set the appropriate compressor in AVI file type for compression. We recommend downloading the XVID codec. In Analysis mode you can then select your datafile and click AVI compress.
  • Page 30 The shutter bar determines the light exposure duration (brightness). If the light is too dark, use the gain bar to increase brightness by software. The JPEG quality is inverse to the compression. 80% means good quality and low compression. With the HDR option, you are able to increase the dynamic from 60dB up to 120dB if you have an image with a low dynamic range (e.g.

The settings of the camera depend on the capabilities of the camera. There are huge differences between one webcam and the next in terms of speed, picture quality, and available functions.

  • Page 42: How To Perform A Measurement

    How to perform a Measurement? So let's acquire the data and see the results. The high-speed camera is synchronized exactly to the analog data therefore we can compare the switching times with analog voltage and current. The current is flowing through the fuse for approximately 20 msec before it really switches off and we can see nicely when the spark switches the fuse off.
  • Page 43 Now if we look at the repeated measurement, both cameras show approximately the same time of the event, however, the webcam shows only one frame when the fuse switched off while the DS-CAM camera shows quite a several frames to be able to also see the spark, the movement of the coil and the switch.
  • Page 44 Dewesoft X, only few steps are necessary. After acquisition of the video file and the Dewesoft data, please copy the *.avi camera file to the directory where the Dewesoft data file is located. [Video available in the online version] After this, open Dewesoft X and enter the Analysis mode.
  • Page 45 Trigger time can initially be selected from trigger (so long as the storing of analog data has been triggered from the same trigger source) or in the relative time from start of measurement in seconds. When finished, Dewesoft X will go to the video screen to see the result of the synchronization and the recorder will show the video frame ticks aligned with the analog data.
  • Page 46 In order to store the synchronization info for future post-processing once you are done and satisfied don't forget to choose Save.

    Windows network configuration Please enter the Control Panel, go to the Network Connections and right-click on the Port, where your Photron camera is connected to. Go to Properties and select the TCP/IPv4 protocol. Depending on the model the default IP address is usually: camera IP: 192.168.0.10 / set computer to 192.168.0.XXX.

Enabling the camera Dewesoft X go to Settings / Settings / Devices, click the add button and add the Photron FastCam.

  • Page 51: Trigger Setup

    This is the most commonly used wiring. The software triggers even on complex trigger conditions on analog input, and sends the start impulse over Ethernet. The camera sends a pulse, when the first frame is recorded, this is measured back with the very accurate Dewesoft super-counters (102 MHz timebase) for synchronization.
  • Page 52 The camera will start with the beginning of data recording (streaming). This is of less practical usage, because depending on the framerate, measurement duration and camera onboard memory, the acquisition time is limited. Store on Dewesoft trigger - example For connection example, we want to acquire both analog and video data of a hit of an accelerometer with the fingertip.
  • Page 53 The trigger setup looks like shown below. We select fast on trigger, rising edge with a level of 1g. The pre-time is 100ms, post time 500ms. Dewesoft supports complex trigger conditions, such as simple edge, filtered edge, window, pulse width, slope, delta...

  • Page 54: Camera Setup

    Camera setup In the video setup, you can see all available cameras. Set the camera to Used, then enter the Setup. The screen on the next page shows the Trigger setup and the Camera settings, as well as a live preview for adjusting the setup (focus, light source, etc).
  • Page 55 Please select the Counter and adjust the level to 0.5, as this is a digital channel (0 to 1). When the camera is started over Ethernet, depending on system load and operating system there will be a delay to the storing trigger. This is usually around 50...100ms (in the example below around 70ms, red line).
  • Page 56 If you copy these files from the Photron CD to Dewesoft Addons folder, they will be used automatically. Files are optimized for 1000 fps frame rate and picture will not be optimal when other frame rates are selected. If you do not have these files or factory calibration data is not satisfying or for any other reason the picture is grainy and/or contains fixed shading pattern, you have to calibrate the sensor to get a better picture.

  • Page 57: Video Download

    Video download After the measurement, Dewesoft will show the whole recorded video data. You can navigate without noticeable delay, however, it is only accessing the camera onboard memory. If you have verified the data to be good, you can finally download the video file to the computer.
