Investigation of extended depth-of-field f/8 camera with optimized cubic phase mask and digital restoration

An investigation of extended depth-of-field camera with optimized phase mask and digital restoration is presented. The goal of this paper is to implement the wavefront coding technique without affecting much of the original design, and the design has taken the complexity of imaging system into consideration. The optimized strength of cubic phase...

The influence of phase mask position upon wavefront coded system: doublet imaging system

Cubic phase wavefront coding technique is applied to an imaging system with the aim of extending the depth of field (DOF). The design is based on the wavefront coding method proposed by Dowski and Cathey¹. The method employs a cubic phase mask (CPM) to modify the point spread function (PSF) of the imaging system under incoherent...
