Abstract
An Incoherent Fourier ptychographic imaging system. Multiple known light patterns are projected sequentially onto a target and images of the combined pattern and target are recorded by a camera, with the images being processed using an optical transfer function (OTF). The camera and projection system are aligned along the same optical axis. The known illumination patterns and the optical transfer function (OTF) are combined in an iterative algorithm to generate an image with resolution greater than would be achieved by uniform illumination of the target and imaging with the camera.
