Abstract

A precision-variable laser-electron method and equipment for measuring 2D tilt angle feature that a reflector is arranged above the liquid surface or an object floating on the liquid surface, and the multiple optical reflections are used to amplify the change of tilt angle, so realizing high-precision and precision-variable measurement of tilt angle. The number of reflections and amplification coefficient can be regulated by its equipment. Its advantages are simple structure, small size, low cost and high stability and reliability.

Description

[0001] 1. Fields: [0002] The invention relates to an inclination measuring device, and further relates to a variable-precision photoelectric inclination measuring method and a device thereof. 2. Background technology [0003] At present, the tilt angle sensor mostly adopts the structure of gravity pendulum. Through the basic principle that the direction of gravity of an object always points to the center of the earth, the change of the inclination angle is converted into a change of position to realize the measurement of the inclination angle. The extraction of tilt angle change signal is mainly realized by laser displacement measurement and PSD photoelectric conversion device. There is also a new type of SMR sensitive element to convert the change of the tilt angle into an electrical signal output. Another type of inclination measurement uses an inductive measurement sensor to determine the position of an object that can move relative to a fixed housing, thereby enabling ...
