Abstract
We report speckle-free digital holographic phase microscopy (DHPM) and tomography using partially spatially coherent monochromatic light with improved image sharpness, resolution and phase noise. Effects of high spatial and temporal coherence of laser light in DHPM, such as speckle effect, spurious fringe generation are discussed and these effects lead to poor phase reconstruction. We present our recent work on the speckle-free phase microscopy and spatial coherence gated tomography with improved phase reconstruction and resolution.
