Abstract

1521269 Automatic focusing system HONEYWELL Inc 20 Nov 1975 [4 Dec 1974] 47731/75 Heading H4D The automatic focusing system of Fig. 1, already described in Specification 1,448,424, is modified into a more compact assembly by forming the two arrays of detectors 1, 3 on the same semi-conductor chip 217, Fig. 2 (arrays 213, 215) together with the signal processor 39. The chip together with optical means (221, 223, 225) for producing the two images on the arrays are mounted in a common housing to form a module 219.
