Improved Exponential Phase Mask for Generating Defocus Invariance of Wavefront Coding Systems
Wavefront coding is an effective way to extend the depth of field of optical imaging systems. The invariant defocusing imaging feature can be obtained by adding a phase mask with a suitable form to the aperture of a typical optical system. Traditional exponential phase mask defocusing optical charac...
