    1. General SW-2001T-CL is a 3CCD line scan camera using three 2048 pixel line sensors mounted on a prism, for the R, G and B channels. It operates with a 40 MHz pixel clock, resulting in a maximum line rate of 19 047 lines per second.

    11(-),24(+) 12(-),25(+) 13,26 Shield The SW-2001T-CL follows the Camera Link standard in all respects. Please refer to the Camera Link version 1.1 specifications for detailed information on bit assignments of 24-bit RGB and 30-bit bit output. 5.3. Input and output circuits 5.3.1.

  • Page 10: Een / Xeen Output (Exposure Enable)

    SW-2001T-CL 5.3.2. EEN / XEEN output (Exposure Enable) This output corresponds to the exposure (accumulation) time of the camera. It works together with all operation modes. It is, however, not active when the test pattern function is enabled. The EEN signal is available at the Camera Link connector and at the 12-pin connector at the same time.

    (the inverse of line rate). This also allows a fixed exposure time, independent of the line rate. In the SW-2001T-CL the exposure time can be set individually for all three channels.

  • Page 12: Pixel Gain (Flat-Field) Correction (Prnu Correction)

    SW-2001T-CL 6.2. Pixel Gain (flat-field) correction (PRNU correction) Pixel Response Non-Uniformity is, as the name expresses, a non-uniformity of the response of each individual pixel. This means that for a fixed light level each pixel will have a slightly different output level (response).

  • Page 13: Shading Correction

    SW-2001T-CL under the operating conditions (exposure time and line rate) that will be used by the application. After correction: Flat dark signal response from pixel to pixel Average 6.4. Shading correction Shading is caused either by illumination with uneven distribution of light across the surface, or by vignetting towards the edges of a lens.

  • Page 14: Operation Modes

    6.6. Operation modes The SW-2001T-CL provides three basic modes of operation: No-shutter, Shutter-Select and Pulse Width Control (PWC). The Shutter-Select and PWC modes also allow the user to set the exposure time independently from the scan rate, by making use of the electronic shutter (the Exposure Control Gate of the CCD sensor).

  • Page 15: Shutter Mode With Internal Line Rate Generator

    SW-2001T-CL 6.6.1. No-Shutter mode with Internal line rate generator In this mode the camera does not accept an external trigger signal, as the line rate is generated from an internal clock (user programmable, command LR). The exposure time is directly proportional to the line rate (T = 1/line rate).

  • Page 16: Shutter Mode With External Trigger

    SW-2001T-CL 6.6.2. No-Shutter mode with External Trigger In this mode, the exposure time is directly proportional to the line rate. The line rate is generated externally by a trigger signal. This mode is used when an external trigger signal is available, e.g.

  • Page 17: Shutter-Select Mode With External Trigger

    SW-2001T-CL EI=1(tracking with G) Programmable exposure PER/PEG/PEB=80 to 2150400 (in 25ns steps) Important note: • If using individual exposure, the EEN signal represents the channel with the longest exposure time Fig. 11 Shutter-Select mode with Internal line rate generator (and individual exposure) 6.6.4.

  • Page 18: Pulse Width Control (Pwc) Mode

    SW-2001T-CL Important note: • If using individual exposure, the EEN signal represents the channel with the longest exposure time Fig. 12 Shutter-Select mode with External trigger (and individual exposure) 6.6.5. Pulse Width Control (PWC) mode In this mode, the user has full control of both the line rate and the exposure time of each line via the External Trigger input.

  • Page 19: Auto Reset Mode

    6.6.6. Auto Reset mode In this mode, when the interval of the trigger pulse is more than 55ms, the SW-2001T-CL automatically returns to continuous operation with the line rate of 52.5μs . At this time, DVAL and Video OUTPUT are disable in order to prohibit charge due to dark current to add up in the sensor in standby periods.
