Fourier ptychographic microscopy (FPM) is a recently developed computational imaging technique, which has high-resolution and wide field-of-view (FOV). However, due to the lower light efficiency of the off-axis LEDs, the exposure time of dark-field images has to be extended to improve the signal-to-noise of dark-field images. In addition, effected by the spherical illumination wavefronts of LEDs, the wavevectors of full-FOV are different.
