    1. General The CV-L105 is a high-speed 3CCD color line scan camera with 2048 pixels resolution. It features digital LVDS RGB output with 30 MHz pixel rate, allowing line rate up to 14285 lines/second. An exposure control function facilitates constant exposure time, independent of the scan rate.

    5.4.2. Trigger input The camera is triggered by an EIA-644 LVDS input signal pair. (+EXT TRIG in/ -EXT TRIG in (on pin #19 and pin #53)). Depending on the configuration of the camera, this input can provide operation in 4 modes: Internal Trigger.

    6. Functions and Operations 6.1. Principle of operation A line scan camera works according to the same principle as a fax machine, also sometimes referred to as a “push broom” operation. It captures a single line at a time (horizontal), and requires either the object or the camera to be moving to create the vertical direction of the image.
  • Page 9 In order to maintain the same vertical resolution, the encoder needs to generate 2048 pulses, for a travel of 1000 mm. With a max line frequency at 14.285 lines/sec. the vertical scanned length is 0.488 mm x 14285 = 6971 mm/sec. CV-L105 Encoder Fig. 10. Specifying an encoder. - 8 -...

    6.2. Trigger modes Internal Trigger. Scan mode. The camera will operate continuously with its internal trigger. The exposure is equal to the scanning time set by the SCAN parameter via RS-232C only. SHUTTER parameter has no meaning here. SCAN value 150 µs through 32.5 ms. Internal Trigger.
  • Page 11: Internal Trigger. Scan Mode

    6.2.1. Internal Trigger. Scan mode. In this mode, the camera does not require an EXT TRIG signal to be issued to the camera. The line rate (scan rate) is generated inside the camera. The camera will operate continuously with its internal trigger. The exposure time is equal to the scanning time set by the SCAN parameter via RS-232C.
  • Page 12: Internal Trigger. Shutter Mode

    6.2.2. Internal Trigger. Shutter mode. In this mode, the camera does not require an EXT TRIG signal to be issued to the camera. The line rate (scan rate) is generated inside the camera. The camera will operate continuously with its internal trigger. The scanning interval is equal to the time set by the SCAN parameter.
  • Page 13: External Trigger. Scan Mode

    6.2.3. External Trigger. Scan mode. In this mode, the camera requires an EXT TRIG signal to be issued to the camera. The trigger signal is typical taken from an encoder. The exposure time is equal to the trigger interval. On the EXT TRIG input positive going edge the ongoing integration period is terminated and charge is read out.
  • Page 14: External Trigger. Shutter Mode

    6.2.4. External Trigger. Shutter mode. In this mode, the camera requires an EXT TRIG signal to be issued to the camera. The trigger signal is typical taken from an encoder. The scanning time is equal to the trigger interval. The exposure time is equal to the trigger low period (pulse width).

    CV-L105 6.3. Other functions 6.3.1. Binnig Binning is a function where the signal from two neighbour pixels are added and read out as a single pixel. The sensitivity will be double, but the resolution will be the half. The binning function has no influence on the internal scan rate and shutter setting.
  • Page 16: Configuring The Camera

    7. Configuring the Camera All configuration of the CV-L105 camera is done via the RS-232C port, which is factory setting. Binning and pixel rate settings can also be controlled by TTL signals into the interface connector or internal jumpers. From the factory, the camera will start up with the factory default.
  • Page 17: Clock Select

    CV-L105 Fig. 18. Shutter window 7.1.1. Clock Select With Clock Select two speeds can be selected, 15 MHz or 30 MHz. The 15 MHz operation will limit the maximum line rate (scan rate) to 7 172 Hz. It is recommended when a cable length of more than 20 metres is used or in applications where high RFI fields may be experienced.

    7.2. Configuration via I/F connector and jumpers The binning function, pixel rate and RS-232C function can be controlled by TTL inputs on the 68pin Hirose interface connector and with jumper settings. Below table describe the possible states of these inputs. Please refer to fig. 7. for principle. RS-232C contr.
