OPTICAL DEVICE FOR SORTING PARTICLES BY SIZE

Sorting is prerequisite to measurement, analysis, and detection of particles. This invention sorts aerosol or colloidal particles by size using optical forces. It consists of a laser-pumped optical cavity that establishes a relatively large, high-intensity standing-wave optical field. Particles...

Optical Flow Meter

Optofluidics is the marriage of microfluidics and optical technology. The NIST optical flow meter provides on chip assessment of flow and heat transfer resulting in improvement in fluid metrology and advances in biological sensing. Most current pressure measurements rely on external pressure...

OPTICAL FREQUENCY COMB-BASED COHERENT LIDAR

A coherent laser radar that uses two coherent femtosecond fiber lasers to perform absolute ranging at long distance. One coherent femtosecond fiber lasers acts as a source and the other as a local oscillator for heterodyne detection of the return signal from a cooperative target. The system...
