Deep deconvolution of object information modulated by a refractive lens using Lucy-Richardson-Rosen algorithm
A refractive lens is one of the simplest, most cost-effective and easily available imaging elements. Given a spatially incoherent illumination, a refractive lens can faithfully map every object point to an image point in the sensor plane.

In recent years, there has been a significant transformation in the field of incoherent imaging with new possibilities of compressing three-dimensional (3D) information into a two-dimensional intensity distribution without two-beam interference (TBI).

We present the autofocusing and self-healing properties of aberration laser beams (ALBs) in a turbulent media. The ALB is generated by a diffractive optical element (DOE) whose phase profile consists of radial and periodic angular dependence.

Resolution for the modified point spread function (PSF) of asymmetrically apodized optical systems has been analysed by a new parameter half-width at half-maximum (HWHM) in addition to the well-defined parameter full-width at half-maximum (FWHM).
