Total internal reflection (TIR) holographic microscopy uses a prism in TIR as a near-field imager to perform quantitative phase microscopy of cell-substrate interfaces. The presence of microscopic organisms, cell-substrate interfaces, adhesions, and tissue structures on the prism's TIR face causes relative index of refraction and frustrated TIR to modulate(More)
Structured illumination microscopy (SIM) is a wide-field technique that rivals confocal microscopy in optical sectioning ability at a small fraction of the acquisition time. For standard detectors such as a CCD camera, SIM requires a minimum of three sequential frame captures, limiting its usefulness to static objects. By using a color grid and camera, we(More)
