Abstract

This paper presents the latest developments on filter-wheel based multispectral imaging systems as well as their extension to making 3D images. The system, capable of producing high spatial resolution images on a spectrum spanning from 400nm to 1050nm (in 12 steps of 50nm (configurable) with 50nm or less bandwidth) can be used, without hardware change. To produce 3D image stacks where the height resolution is given by the numerical aperture of the optics used and the reproducibility of the image plane moving motor is also possible. This paper introduces the reader to spectral imaging and to 3D measurement techniques. The main parameters and relevant publications of/about the industrial monocular multispectral 3D-Imager are then presented. Correction of chromatic aberration on filter wheel system, a key idea for 3D image reconstruction, is revised. 3D imaging capabilities of the system as well as proper calibration are introduced. Selected applications and algorithms are presented towards to the end of the paper.
