Abstract
A lenslet array system includes (i) a first assembly including a field-limiting mask and a first lenslet array having an associated focal plane and (ii) a second assembly including a second lenslet array accepting light from the first assembly. The first lenslet array accepts a full field of view in excess of 20 degrees and forms a plurality of image sections of the associated object on an intermediate image plane which is substantially coplanar with the focal plane associated with the first lenslet array. The first lenslet array includes a plurality of positive power lenslets. Each of the plurality of lenslets has a focal length f.sub.1 of less than 15 mm and accepts a unique segment of the full field of view subtended by the associated object. These segments of the full field of view together comprise the full field of view, and each of said lenslets forms one image section corresponding to its segment of the full field of view. The second lenslet array of the second assembly accepts light from the first assembly. The second lenslet array has a plurality of positive power lenslets. Each of the lenslets of the second lenslet array (a) has a focal length f.sub.2 which is less than 15 mm, (b) reimages one of the image sections located at the intermediate image plane and creates an inverted real image of this image section on the final image surface, and (c) together with other lenslets of the second lenslet array creates a single image of the associated object.
