Illumination-Direction Multiplexing Fourier Ptychographic Microscopy Using Hemispherical Digital Condensers
 
Show general info
Content: Fourier Ptychographic Microscopy (FPM) is an image reconstruction technique based on directionally varying sample illumination conditions. In this work, we used a hemispherical digital condenser (HDC) to implement illumination-direction multiplexing (IDM) Fourier ptychographic microscopy. Many simulations were conducted where we explored four possible illumination patterns using the HDC. This technique was successfully used to image a sample and recover it's associated phase. We found that the illumination-direction multiplexing(IDM) technique with ring-like illumination patterns could be used to image photonic crystals with subwavelength periods using traditional microscope condensers with variable numerical aperture.
