An optomechanical accelerometer that uses light to measure acceleration. Credit: F Zhou/NIST An accelerometer that uses laser light instead of just mechanical strain can register changes as small as ...

In the present study, the theoretical framework underlying interferometric measurement using multimode lasers—forming the basis of laser vibrometry—is comprehensively described. A numerical simulation ...

Pre-shaped microbeams, curved or inclined, are widely used in MEMS for their interesting stiffness properties. These mechanisms allow a wide range of positive and negative stiffness tuning in their ...

Researchers at the National Institute of Technology (NIST) have developed a new type of accelerometer based on lasers and optomechanical principles rather than the traditional mechanical strain gauges ...

Setting the stage for a new class of motional sensors, researchers have developed a new ultrasensitive, microchip-scale accelerometer that uses laser light to measure displacement. Beyond consumer ...

Researchers at the California Institute of Technology (Caltech) and the University of Rochester have developed an ultrasensitive microsensor accelerometer. Their device uses laser light to gauge ...

Illustration showing how a single laser beam is converted into four beams after diffracting from a patterned surface. These beams are then used to trap ultracold atoms in the new accelerometer.
