Paper Abstract

According to the image relay concept in the optical amplification system, submicrometer resolution of a digital image processing system has been given in this paper. The accuracy and precision of the system has been examined by using a standard identification reticle, and some measurement results of a small focal spot through a computer generated holographic lens have been given.
