METHOD AND SYSTEM FOR FAST MICROSCANNING

摘要

An imaging system for implementation of a microscan includes an array of sensing elements that define an image plane. A movable lensing system is adapted to focus an image on the image plane. Piezoelectric positioners are provided to move the lensing system a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens back and forth or in a predetermined pattern provides dithering of the image so that microscanning can be employed.
