Abstract
A laser gauge utilizing a parabolic mirror projects a plurality of laser beams parallel to the principal axis of the parabolic mirror. A plurality of reflector means, e.g., three reflector means, are established in front of the parabolic mirror and are positioned to reflect the laser beams into a plurality of groups of paths at different angles to scan across the object to be measured. Photodetector means is mounted to receive the laser beams after scanning of the multiple dimensions of any such object. Output means, including a microprocessor, is connected to receive the output of the photodetector means to determine the dimension along a plurality of crosssectional dimensions of any object in the groups of paths. When three such groups of paths are used, they may be at 120 degrees each with respect to the other to measure the cross sectional dimension of the object at three different places. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
