Camera boosts responsivity The Eclipse single-output linescan camera delivers 100X greater responsivity than existing units. Available in 512, 1024, and 2048 resolutions, this bidirectional camera uses a 512 x 96, 1024 x 96, or 2048 x 96 time-delay and integration sensor, respectively, runs from a single voltage (12-15 V), and provides programmable gains and offsets. At line rates to 64 kHz, it delivers 8-bit RS-644 LVDS data at selectable speeds to 40 MHz. Built-in processing for fixed-pattern noise/ pixel-response nonuniformity correction compensates for nonuniform lighting and optics degradation.

Frame grabber makes monochrome The M-vision 510 monochrome PCI frame grabber digitizes video and transfers digital data at 132 Mbytes/s to system memory or directly to a VGA card. It captures composite RS-170/CCIR and noninterlaced video from progressive-scan cameras. A phase-locked loop and adjustable digitizing range allow a wide dynamic range for gain and offset with less than 3-ns jitter. The board is PCI 2.1-compliant and supports scatter/gather under Windows 3.x/95/98/NT so that addresses can be generated and stored and one interrupt per field/frame serviced. A software developer's kit, TWAIN and MCI drivers, and DirectDraw software are supported. MuTech Corp.,Billerica, MA 01862; (978) 663-2400.
