Synthetic Aperture Phase Microscopy Enables Subcellular Imaging

Facebook X LinkedIn Email
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...Read full article

    phase
    In optics and photonics, "phase" refers to a property of electromagnetic waves, such as light, that describes the position of a wave at a given point in time within its oscillation cycle. More specifically, it indicates the position of a wave relative to a reference point, typically the starting point of a cycle. When discussing phase in optics, it's often described in terms of the phase difference between two waves or the phase of a single wave. The phase difference between two waves is the...
