Incoherent optical process
WebIncoherent Optical Fluctuation Flowmetry (IOFF) is an optical technique for assessing tissue blood flow (BF). This technique is based on the spectral analysis of low-frequency fluctuations in the registered optical signal caused by blood volume changes inside a tissue. The technique can be realized using an optical probe with LEDs. The aim of this study was … WebMar 1, 2024 · Abstract. As a new high-speed intelligent computing method, optical neural network (ONN) has the advantage of realizing lower or even zero power computing. For example, the diffractive neural networks based on passive diffraction layer can work without power consumption. However, in the realization methods of current ONN, coherent light is …
