Compact Lens-less Digital Holographic Microscope for MEMS Inspection and Characterization
Published on: July 5, 2016
Abstract:
Optical scanning holography requires interference optics, which separates a laser beam into two paths and recombines the two path beams after being modulated spatially and temporarily. This requires high accuracy and stability of the apparatus with a highly coherent light source. In this Letter, we propose a coaxial scanning holography (CSH) capable of realizing scanning holography with high stability and low complexity by forming a scanning beam in a single optical path using a geometrical phase shift. An experimental verification of the CSH by optical acquisition and subsequent reconstruction of the hologram is reported.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
