Abstract

Abstract

According to the low precision and limited measuring range of a domestic independent-developed laser displacement sensor, a method which simulates the whole optical system using optical design software is proposed in this paper. Based on the analysis of each part's optical properties in the system, an optical system of laser displacement sensor with the measuring range of (5010) mm is designed to meet the practical requirement. With a separate approach, the whole optical system can be divided into two parts to be designed separately. The first part is a shaping lens of laser beam, which requires that the emerging spot is small and uniform in the effective working range. The result of design shows that the spot size can be controlled in the order of 10-1 mm. The other part designed is an imaging lens, which receives the scattered light from the measured surface. The properties of this part require that there is a certain angle between the planes of object and image and the optical axis. In the end, the designed results demonstrate that the images match Scheimpflug's condition.
