Aiming at problem that format laser displacement sensor can not satisfy geometry size detection requirements in complex test environment

propose a design method of discrete laser displacement sensor.This method can discretely decorate the laser source and the photoelectric detector according to detection requirements

and set the parameters of the division set in the system on the basis of laser rangefinder principles

then realize function of laser displacement measurement through methods of data acquisition and calibration modeling.Finally

it verifies feasibility of the method through a design example.
