    Lt-200cl 5 1. General lt-200cl is a 3cmos line scan camera using three 2048 pixel line sensors mounted on a prism, for the r, g and b channels. It operates with an 80 mhz pixel clock, resulting in a maximum line rate of 30,383 lines per second. The camera outputs digital data in 3 x 8 bits or 3 x 10...
