Design and demonstration of a six-channel multiresolution imaging system

Abstract

Multichannel imaging systems consist of multiple channels that have different imaging characteristics (fields-of-view and angular resolutions). We design and demonstrate a six-channel multiresolution imaging system that can achieve a relative magnification ratio of up to 10 times between the channels and, at the same time, result in different depths-of-field. The imaging system consists of two double-sided lens arrays made of PMMA material, a baffle to eliminate possible cross talk between neighboring channels, and a Sony full-frame image sensor. The imaging system was tested by capturing images of stationary and moving objects. The acquired images exhibit different resolutions, fields-of-view, and levels of blur proving our concept.
