초록

A focus detecting system includes first and second auxiliary optical devices for forming first and second auxiliary images of an object on first and second detector devices, respectively, which in some illustrated embodiments are closely disposed on a single substrate. Each detector device includes a plurality of linearly displaced light responsive elements, each element in the first detector device having a corresponding element in the second detector device in relatively the same position with respect to the detector devices. One of the optical devices...
