摘要
Systems and methods are disclosed for recovering both phase and amplitude of an arbitrary sample in an optical microscope from a single image, using patterned partially coherent illumination. This is realized through the use of a encoded light source which embeds several different illumination patterns into color channels. The sample is modulated by each illumination wavelength separately and independently of each other, but all of the channels are sensed by the imaging device in a single step. This color image contains information about the phase and amplitude of a sample encoded in each channel, and can be used to recover both amplitude and phase from this single image, at the incoherent resolution limit. Further, extensions of this method are shown which allow the same recovery of a sample whilst it is moving during a single exposure using a motion deblurring algorithm.
