We propose to use alternate direction method of multipliers (ADMM), to improve computational robustness of Fourier ptychographic microscopy (FPM). This method is highly parallel so it can be run efficiently on GPU or distributed CPUs.

With the development of conventional photography, many new imaging systems are used in equipment manufacturing, medical sciences and entertainment industry. We describe the architectrue and characteristic of DMD camera. According to its advantage in temporal resolution, spatial resolution and dynamic range imaging, we employ it into edge detection, dynamic imaging and 3D shape measurement. The experimental result shows the performance of DMD camera.
