EMBEDDED PUPIL FUNCTION RECOVERY FOR FOURIER PTYCHOGRAPHIC IMAGING DEVICES
First Claim
Patent Images
11. A method of Fourier ptychographic imaging employing embedded pupil function recovery, the method comprising:
- illuminating a sample from a plurality of incidence angles using a variable illuminator;
filtering light issuing from the sample using an optical element;
capturing a plurality of variably-illuminated intensity image distributions of the sample using a radiation detector; and
simultaneously updating a pupil function and a separate sample spectrum, wherein the sample spectrum is updated in overlapping regions with Fourier transformed variably-illuminated intensity images measurements, wherein the overlapping regions corresponds to the plurality of incidence angles and the numerical aperture of the lens; and
inverse Fourier transforming the recovered sample spectrum to recover an image having a higher resolution than the intensity images.
