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...

OPTOELECTRONIC NEURAL NETWORKS

Optoelectronic neural networks comprise a system of interconnected processing units (neurons) interconnected by integrated photonic waveguides. The processing units receive photonic signals from other units. Each unit sums the received signals on a waveguide-integrated photon detector, and when the...
