Compact Side and Multi Angle Illumination Lensless Imager and Method of Operating the Same

A system for subpixel resolution imaging of an amplitude and quantitative phase image, the system including a waveguide having a top plane, a bottom plane, and two sides, an array of light sources emitting first befit beams from one side of the two sides of a waveguide, a holographic photopolymer film positioned on the top plane or the bottom plane of the waveguide and arranged to be illuminated by the first light beams from the array of light sources via the waveguide and to produce second light beams by diffraction, and an imaging device for capturing interference pattern light beams that passed through a sample, the sample arranged to be illuminated by the second light beams.
