High focal depth by apodization and digital restoration

Not Accessible

Your library or personal account may give you access

Abstract

We show that by using an iterative, digital restoration algorithm (Wiener or Kalman), it is possible to improve substantially the defocused optical transfer function of a previously apodized optical system. Consequently, high focal depth can be achieved by the use of an apodizer at the recording step, and a posteriori step of digital restoration. Computer-simulated images exhibit the focal depth achieved.
