1. An image detection array comprising:
- lens means for transmitting radiation from a remote object;
a lenslet matrix comprising a predetermined number of lenslets arranged in rows and columns and mounted to receive radiation transmitted by the lens means; and
a detector array mounted adjacent the lenslet matrix and comprising a plurality of substantially equal sized detectors arranged in pairs with at least one pair behind each lenslet so as to receive an image of the exit pupil of the lens means, the outputs of the detectors producing a first resultant signal indicative of the shape of the remote object.

Abstract
A two dimensional optical array of lenslets and detectors is provided. The outputs of the detectors are combined to produce a signal indicative of the characteristics of an object being viewed while the output of selected detectors are compared to produce a signal indicative of the range to the object.
