Researchers at The Chinese University of Hong Kong (CUHK) have developed a phase-reliant method of synthetic aperture microscopy (SAM). The method, introduced as “high spatial and temporal resolution synthetic aperture phase microscopy,” or “HISTR-SAPM,” features a setup of digital micromirror devices (DMDs) — electronic components commonly used in digital projectors and that contain a matrix of micromirrors — and overcomes previously existing limitations to SAM tied to spatial resolution and frame rate.
Scientists can individually and electronically control the orientation of micromirror matrices in DMDs at high speeds, which allowed the researchers to develop and implement a system in which they…READ MORE
