    Optomechanical Accelerometer Outperforms Comparable Instruments

    Article obtained from Photonics RSS Feed.

    A laser light-powered accelerometer — a sensor that detects sudden changes in velocity — operates over a greater range of frequencies than comparable, nonoptical instruments, and at a higher rate of accuracy. Researchers from NIST developed the optomechanical accelerometer device, which is 1 mm thick and bypasses reliance on mechanical strain by using light as its activator. The device, the researchers said, also does not require periodic calibrations.

    Though other light-powered accelerometers exist, the NIST-design delivers higher accuracy than similar and comparable instruments.

    All accelerometers record changes in velocity by tracking proof mass, or the position of a freely moving mass, relative to an unmoving…
