Certain embodiments pertain to Multiplexed Fourier Ptychographic imaging systems and methods. In one example, the Multiplexed Fourier Ptychographic imaging system includes an LED array configured to illuminate a sequence of LED patterns for illuminating a sample being imaged. The system includes LED circuitry configured to independently control power to turn on multiple LEDs simultaneously in each LED pattern of the array. The system has a light detector that acquires a first set of lower resolution images of the sample each image acquired during exposure time during illumination by a unique LED pattern. The system uses the first set of lower resolution images to generate a second set of lower resolution images associated with each LED in the LED array and iteratively updates overlapping regions in the Fourier domain with the second set of lower resolution images to generate a higher resolution image.
