ASPHERIC LENS HAVING A PLURALITY OF LENSLETS DISPOSED SUBSTANTIALLY CONTIGUOUSLY IN AN ARRAY |
摘要 |
The lens includes a plurality of lenslets arranged substantially contiguously in an array. Each lenslet is adapted to receive radiation from a particular zone not substantially overlapping with adjacent zones, and to focus said radiation to a predetermined common point. A detector may be located adjacent said common point and preferably includes at least two detector elements each to detect infra red radiation from a different zone.
