Paper Abstract

A very thin image capturing system called TOMBO (Thin Observation Module by Bound Optics)was developed with compound-eye imaging and post digital processing. With the prototype system, some excellent results have been obtained. In this paper, we focus on a multispectral imaging system as an application of the TOMBO. In the system, it is possible to observe specific points on the target by multiple photodetectors with a special arrangement of the system. A filter array is inserted in front of the image sensor to observe the spectral distribution of the target. A captured compound image is reconstructed by an extended version of the pixel rearrange method. The pixels of the captured image are geometrically rearranged onto a multi-channel virtual image plane. Experimental results of the image reconstruction show effectiveness of the proposed algorithm.
