The Optical Quadrature Microscope measures the amplitude and phase of an image. The concept is based on the use of polarized light to produce interfereograms of the image with four reference beams each having a different phase. These four interferograms are combined to produce the complex electric field amplitude. This information allows the user to see contrast features not available in other microscopes, and is critical to any three­dimensional reconstruction.
