    Cv-l108cl 5 1. General cv-l108cl is a 3ccd line scan camera using three 512 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 70,922 lines per second. The camera outputs digital data in 3 x 8 bits or 3 x 10 ...

    Cv-l108cl 10 6. Functions and operation 6.1. Basic functions the cv-l108cl is built around three high-performance ccd line scan image sensors mounted on a prism block, as illustrated in figure 6. During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes (acti...

    Cv-l108cl 11 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). To cor...

    Cv-l108cl 12 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. The shading correction incorporated in the camera will compensate for this effect by as much as 20% of the brightest signa...

    Cv-l108cl 13 6.6. Operation modes the cv-l108cl 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 (...

    Cv-l108cl 14 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 exp = 1/line ...

    Cv-l108cl 15 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. From an encoder, and the scan rate can ...

    Cv-l108cl 16 6.6.3. Shutter-select mode with internal line rate generator this mode allows the user to have full control of the line rate and the exposure time individually, by programming separate timing generators.
