Color camera uses three chips The TR-31 and TR-32 Trillium color linescan cameras use prism beamsplitting technology with dichroic (interference) filters and three custom IL-CC sensors to deliver three color signals (red, green, and blue) from a common optical axis for inspection applications. At 1024- or 2048-pixel resolution, the camera's three channels transmit EIA-644 (LVDS) data at 25 MHz, each resulting in up to a 21-kHz line rate, with an 8-bit output from 10-bit digitization. The TR-31 camera comes with a Nikon F lens mount; an associated 55-mm lens is optional; the TR-32 camera offers a Canon FD lens mount and an optional ƒ/1.4 matched lens. Integrated signal processing by a 32-bit microprocessor helps perform programmability, pixel-by-pixel flat-field correction for FPN, PRNU, and automatic white-color balancing. An optional beamsplitter-matched lens provides black to white with a single transition pixel. Self-calibration and self-color balancing capabilities adapt automatically to changing lighting conditions.
