3 Overview

Laser Caliper is measured using a laser beam to scan the object geometry rapid non-contact measuring instrument. It uses A semiconductor laser as the light source, through the polygon scanning mirrors and a rear lens group of the optical beam emitted by a laser, form Into the continuous high-speed scanning beam parallel to the optical axis, to be placed in the measurement area of the workpiece speed scanning by laser The receiver receives the scanning beam time blocked. By known laser scanning speed is calculated to obtain the workpiece few What size. The measurement principle shown in Figure 1. Figure 1 laser caliper measurement schematics 2- The transmitter section;; 1- 3- laser scanning rotating mirror; 4- workpiece; 5- photoelectric conversion; 6- data processing; 7- receiver section Laser Gauge for measuring needle gauge, plug gauge rod and other precision measuring tools or standard workpiece diameter circle and jump Move, can also be used for fragile, deformation, heat, clean parts for non-contact measurement. Laser Gauge according to its range and accuracy, with different resolution and range. According to its function, shock Light Gauge function into two functions, and no self-calibration with self-calibration. ......
