Nonlinear edge enhancement imaging based on Laguerre-Gaussian superimposed vortex filters

|
By Xiufang Li, Yanqian Sun, Xukun Cheng, Lihang Zhao
| Optica Verified
Nonlinear reconstruction, which is based on the principle of cross correlation, is a commonly employed reconstruction technique in incoherent correlated digital holography systems. However, the modulation of phase masks in these systems is suppressed during the reconstruction process, resulting in an inability to express the characteristics of the phase masks. Consequently, achieving edge enhancement within these systems is constrained.
