Five dimensional information encoding using spiral phase masks in coded aperture imaging
In this study, we extend the multidimensional capabilities of interferenceless coded aperture correlation holography (I-COACH) by incorporating orbital angular momentum (OAM) as an additional encoding dimension through spiral phase masks. Unlike previous work on vortex speckles generated via self-interference of OAM be...
