Abstract
We present a novel technique for coherence engineering of the microscope illumination based on a DLP projector providing fast (millisecond range) switchable both temporal and spatial coherence design. Its performance is experimentally demonstrated for speckle-noise free quantitative phase imaging with different spatial coherence states. Strategies for design and control of the light coherence are discussed.
