LC - Laser Caliper Systems
	High Speed, Large Format, laser light curtain measuring systems Sensor widths from 24" to 24 feet in 24" module increments 2000 line per second measuring speed independent of sensor width 0.005" sensor pixel spacing Up to 30" object thickness between Emitter and Detector with minimal parallax error Integral PowerPC based Hub with VxWorks OS for real time data processing and o/p to NT Host system via Fast Ethernet connection   US Patent 6,947,152 CDN Patent 2,371,602
The Laser Caliper is intended for profiling, inspection, and process control applications where the outside profile and/or location and size of holes is required. Typical applications are: Large punched sheet metal part inspection Web guiding and detection of transmissive defects Lumber gaging - board length and width, log diameter The Laser Caliper provides significant advantages when compared to existing discrete photodiode based systems - No crosstalk between sensors that limits measuring resolution and scan rate True 0.005" pixel spacing 2KHz scan rate independent of system width 36 edges detected simultaneously per 72" of width in standard configuration - more in custom versions
EMITTER MODULE Visible light laser sheet Three overlapping 8.5" wide collimated (< 3mr) beams provide complete 24" wide coverage per module Class II Laser Device DETECTOR MODULE 200 dpi CMOS arrays Integral h/w edge detection electronics Master module with optional slave unit either end. Fibre Optic control and data connection between Master and Hub	HUB Motorola MPC8260 PowerPC based motherboard VxWorks Operating System Fibre Optic interface board supports up to 4 Master detector modules. Fibre optic quadrature encoder and choice of two fibre optic object 'detect' inputs. Fast Ethernet connection (RJ-45 or optional fibre optic) to NT Host Real time data reduction provides simple calibrated edge data on line by line basis, and 2D compressed image at operator selected line count in *.tif CCITT Group 3 fax format.
