Abstract

To reduce the cost of laser displacement sensor trial production and carry out linearity measurement more conveniently

a laser displacement sensor is developed. ZEMAX software is used to optimize the design of the optical system

an appropriate optical lens is obtained

and then select photoelectric elements

a laser displacement sensor with working distance of 100 mm

measuring range of ± 25 mm

linearity of ± 0. 28 % and resolution of20 μm is successfully developed. The sensor has the characteristics of wide measuring range

good linearity and high resolution

which meets the application requirements of precise measurement in industrial scenes.
