Fourier ptychographic imaging systems, devices, and methods

Systemes, dispositifs et procedes d'imagerie ptychographique de fourier

Abstract

A Fourier ptychographic imaging device includes a variable illuminator for providing illumination to a specimen from a plurality of incidence angles; an optical element for filtering illumination issuing from the specimen; a detector for acquiring a plurality of variably-illuminated, low-resolution intensity images of the specimen based on light filtered by the optical element; and a processor for computationally reconstructing a high-resolution image of the specimen by iteratively updating overlapping regions in Fourier space with the variably-illuminated, low-resolution intensity images.
