Camera stops motion
MotionMeter hand-held slow-motion digital imaging camera can capture images for high-speed motion analysis. Digital image capture uses an optional USB-based video-to digital image transfer. Sensitivity ranges from 0.5 to 5 lux at 250 frames/s. Recording rates run at 50 (PAL), 60 (NTSC), and 125 to 1000 frames/s for manual and trigger recording modes. Exposure rates cover 1 to 20 times the recording rate. Frame storage delivers up to 4098 frames with playback rates from 1 to 1000 frames/s, forward and reverse. The camera measures 8 X 5 X 2.7 in., weighs 1.5 lb, and uses a C-mount.

Cameras come in 15 models
HVSOLO 10-bit digital linescan cameras are available in 15 models that offer seven pixel-array lengths, three output tap arrangements, and two pixel sizes. Total pixel data rates range from 40 to 80 MHz, depending on the number of pixels and taps. Sensor resolutions cover 512 X 1 to 3072 X 1 pixels with 14-µm sq pixels; other sensors use 7-µm sq pixels. To compensate for nonuniformities due to the sensor, optics, or lighting, all models include a real-time digital radiometric correction function. A Windows-based camera control- tool software package provides interactive user control of camera functions. All models are supplied with either parallel LVDS or serial Camera Link interfaces. The cameras operate from 15-Vdc power.

Frames grabbed on four channels
PC_Eye_2+ RGB color PCI frame grabber provides four video input channels that can acquire images or image sequences directly into main memory. In quadro mode, the four images are stored in separate memory regions as monochrome images. An on-board sync generator comes with four 75-ohm outputs. Four independent A/D converters digitize data with 8 bits of resolution each at rates between 5 and 32 MHz. Each A/D converter can sample data from the four input ports. Optoisolated trigger inputs with additional outputs are used for camera triggering. Drivers are supplied for Windows 98/Me/NT/2000, and a setup program supports board test and configuration under Windows.

Camera stops action
DALSTAR 1M28-SA stop-action CMOS-area camera provides a 1-Mpixel CMOS image sensor capable of delivering 27 frames/s at full resolution. It features LinLog technology that increases the intrascene dynamic range up to 120 dB for handling applications dealing with large differences in brightness. Global nonrolling shuttering reduces image blur by simultaneously exposing the entire pixel array rather than sequencing the exposure line-by-line. The camera incorporates programmable and diagnostic features that are accessible through a Camera Link MDR26 connector. Packaged in a small housing, it offers 8- or 10-bit digital outputs and can achieve rates of more than 100,000 frames/s with windowing.

Software is updated
Sapera 4.1 image-processing library now provides more than 300 functions and added support features that speed application development. Optimized for Intel's MMX, SSE, and SSE-2 instruction sets, the software library includes the Smart Series, a collection of application-specific libraries for pattern matching (Smart Search), optical character recognition (Smart OCR), and 1-D/2-D barcode (Smart Matrix). Added TWAIN support enables image capture from company frame grabbers without additional programming. DirectDraw 8.1-compliant, the software library extends Windows 2000/XP capability using third-party VGA cards for the Bandit-II Series frame grabbers and user-defined custom camera controls for the Viper-CamLink frame grabbers. Its hardware-independent software libraries are programmable using C-dynamic link libraries (DLLs), ActiveX Controls, and C++ classes. Applications can be developed using Microsoft Visual C/C++ and VisualBasic and Borland C++ Builder under Windows NT/2000/XP.

Camera targets spectroscopy
SpectraCAM line of cooled, randomly addressable, scientific imaging cameras focus on spectroscopy applications. They feature 27 X 27-µm pixels using a 540 X 540-pixel RACID86 sensor or a 1024 X 1024-pixel RACID84 sensor. Proprietary RACID Exposure software automatically varies exposure time from pixel to pixel based upon real-time observation of the signal intensity. Proprietary random-access integration results in a linear dynamic range exceeding nine orders of magnitude or 30 bits using a single exposure period. Antiblooming performance ensures accurate image detail under extreme lighting conditions, and wavelength coverage allows sensitivity from 160 to 1100 nm. Additional coatings are available for deep ultraviolet and direct x-ray imaging. The 16-bit gray-level camera controller uses a Pentium PC with a 100-Mbit/s Ethernet host-controller communications link. Camera software also supports the export of data in various imaging (JPEG and TIF) and spreadsheet formats.
