System makes 3-D measurements The YP20 measuring system operates within a z-axis range of 20 mm to read and measure a part's surface. It uses a laser, a CCD color video camera, 50X optical lens, Sony Trinitron monitor, video capture board, and 450-MHz Pentium II PC. A 230 x 230-mm part stage mounted on a microflat granite table provides x- and y-axis movements within a 110 x 110-mm range. Closed-loop control in all three axes provides 0.1-µm resolution and a z-axis positioning repeatability of ±0.2 µm. Running within Windows 98, the system's inspection software furnishes a range of color, 3-D screen displays for parts' observation, measurement, and analysis.

CMOS sensor is programmable The PresencePLUS pixel-counting sensor consists of a 512 x 384 CMOS pixel array and a programmable processor, controller, lens, lighting, and mounting bracket and cable. It captures a 256-level gray-scale image of a specified area, converts the image to black-and-white pixels, and compares the designated-color pixel count with user-programmable upper and lower threshold values to determine pass or fail decisions. The sensor comes with a fluorescent or visible LED ring lamp; an 8-, 12- or 16-mm C-mount lens; a base-mounting swivel or column-mounting bracket; and a 6.5-, 15-, or 30-ft length of PVC-jacketed, quick-disconnect, sensor cable. The PRC1 hand-held processor-based controller is used to program and monitor the CMOS sensor, displays programming options, monitors options, and captures images on an LCD screen.
