    Lq-050cl 5 1. General the lq-050cl is a 4ccd line scan camera using four 512 pixel line sensors mounted on a prism, for the r, g,b and nir 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 4 x 8 bits or 4 ...
