Abstract: In this paper, a new type of multiaperture optical system, optical compound eye lens (OCEL), is described. There are short focus, large field of view, and mosaic structure of optical lens and detectors in this new type of optical system. The application of multiaperture optical systems for pattern recognition, locating the position of the target and measurement of the direction and velocity is discussed. Multiaperture optical systems inherently perform some degree of optical preprocessing which reduces the amount of information offered to the system to a manageable level and so simplifies pattern recognition. It is pointed out in this paper that the resolving power is equal to the angle between two neighbor lenslets. The clear aperture of OCEL is defined and the concept of overlapping image is advanced. !13
