Frame grabbers blaze
MaxRevolution family of pipeline image-processing frame grabbers for the PCI bus enables image acquisition from Camera Link-compatible digital linescan or area-scan cameras. Units can support up to eight camera taps, each running at up to 85 MHz, that can achieve a 680-Mpixel/s acquisition rate. Based on software-configurable and scaleable Xilinx Virtex II FPGA processing architecture, the frame grabbers can acquire, preprocess, and transfer images and results to host system memory via universal 64-bit, 66-MHz PCI bus interface at sustained rates of up to 360 Mpixels/s. On-board memory is expandable to 1 Gbyte using PC-2100 double-data-rate SDRAM. Units feature pixel gain and offset correction that compensate for gray-scale irregularities in both 1- and 2-D image sensors, on-board Run Length Encoding compression, multitap data reformatting on the fly, and connection to two Camera Link cameras for simultaneous acquisition, pipeline processing, and DMA transfer to host memory. Software support includes the company's Video Layered Library of C++ software-development tools. Datacube Inc., Danvers, MA 01923; (978) 777-4200.

Mix-and-match objectives
Machine-vision optics modular magnification system allows users to mix and match front objectives and back lens assemblies to meet a range of working distances and field-of-view requirements. Primary magnifications of 0.5X to 4.0X are available. With a wavelength range of 486-656 nm, the system components function in nominal working distances of 67, 91, 116, and 141 mm and with a resolution up to 114 line-pairs/mm. Focus adjustment allows a range of field of view and working distances with one set of components. A variety of CCD sensor sizes can be used to a maximum of 2/3 in. Edmund Industrial Optics, Barrington, NJ 08007; (856) 573-6250.

Camera packs power
SI-3170 MegaCamera series of digital 1/2-in. CMOS cameras with C-mount provides 2048 X 1536-pixel resolution and runs at video rates of up to 30 frames/s at full resolution. Cameras use dual 12-bit digitizers to sample two output taps, each at 50 MHz, to achieve 100 Mpixels/s. Both the SI-3170M monochrome and the SI-3170RGB color cameras incorporate the Camera Link interface. Their CMOS sensor array contains 3.3-µm-square pixels that operate in full-frame or window mode. A reduced region of interest (windowing) provides readout rates in excess of 500 frames/s. The cameras are fully programmable via a serial port with flash memory for parameter storage and preset recall. Program-mable functions include sampling clock speed, region-of-interest window, and global gain. Silicon Imaging Inc., Troy, NY 12180; (518) 279-9098.

Camera uses large sensor
DT4000 digital progressive-scan 1-in. CCD camera acquires color or monochrome images with 1600 X 1200-pixel resolution at 10 frames/s. Accucolor technology delivers full 24- or 30-bit color image data. A Camera Link data interface or a parallel LVDS output is available. Camera controls include autoexposure, white balance, gain control, color balance, various trigger modes, and RS-232. Image acquisition and processing are performed at 10-bit pixel depth. Input data output format can be set for 8- or 10-bit pixel depth under software control. Multisync monitor plugs directly into the camera. Composite RGB or individual color plane images as monochrome images can be displayed. Electronic shutter ranges from 1/10 to 1/10,000 s. DuncanTech, Auburn, CA 95603; (530) 888-6565.

Camera shrinks size
Model IK-TF1 3-CCD color camera measures 1.7 X 1.7 X 3.1 in. and weighs 5.47 oz. It provides 570 lines of resolution, a 64-dB signal-to-noise ratio, and a C-mount. Co-site sampling (spatial congruent) arrangement of the camera's three 1/3-in., 410,000-pixel, interline-transfer CCDs results in 10-lux sensitivity, reduced smear, and precise RGB signals. A nine-step electronic shutter covers 1/60 to 1/50,000 s. Key features include automatic and manual white balance, one- or two-pulse random triggers, and an RS-232 serial interface. Toshiba Imaging Systems, Irvine, CA 92713; (949) 461-4986.

Camera sees near-IR
KP-F120 progressive-scan, 2/3-in. black-and-white CCD camera extends sensitivity to the near-infrared area of the light spectrum with output at 900 nm and higher. Resolution is 1392 X 1040 pixels using a square lattice pixel design. Its frame-on-demand function captures images for processing at a selected time using any of three trigger modes. Full scan runs at 30 frames/s, with partial scan readings to 200 frames/s. It measures 58 X 58 X 48 mm and weighs 200 g. Electronic shutter speed covers from 1/30 to 1/50,000 s in eight settings. Other features include an RS-232C port for remote camera control and a 10-bit, dual-channel LVDS/EIA-644 output. Hitachi Denshi America Ltd., Woodbury, NY 1179; (516) 682-4411.
