A Displacement Measurement System Based on Artificial Compound-Eye Imaging for 2½D Space

Abstract

Comparing to the single aperture imaging system, Artificial Compound-Eye (ACE) imaging system has some nice features, such as small size and stereo vision. Based on the pictures captured by ACE, the displacement of an object can be easily deduced. This paper introduces our multiple-focus ACE imaging system. The system mainly consists of (a) a micro-lens array fabricated by Micro-Electro-Mechanical-System (MEMS) technology, (b) a CMOS chip, (c) a 3D mechanical moving stage, and (d) a software module. It can measure the displacements of an object in 212D space without calibration. The experiment validation is included.
