Multiaperture vision systems are of interest in the area of robotic vision. A facsimile of the insect eye may be as useful for transmitting information to robotics as conventional cameras, which are analogous to the human eye. A physical model of one multiaperture vision system, the insect apposition ommatidia, has been successfully constructed. To provide an understanding of the multiaperture vision system, the impulse response of a single eyelet, or ommatidium, was developed. Experimental measurements of the impulse response were found to closely match theoretical results.
