WebJan 2, 2024 · Abstract We propose a new, to the best of our knowledge, method of incoherent optical frequency selection called three-pack frequency-selective incoherent holography. Compressed holography is reconstructed using phase shift intercepts and spatial transfer function convolution in the form of separation without loss of … WebMay 1, 2024 · Incoherent illumination of the imaging system ensures that only the intensity information is manipulated. The encoded information is just an intensity distribution which is advantageous for data storage, simplifying the system structure and processing, and suppressing the information expansion involved in general conventional encryption …
WebAug 4, 2024 · Interplay between dispersion and nonlinearity in optical fibers is a fundamental research topic of nonlinear fiber optics. Here we numerically and experimentally investigate an incoherent continuous-wave (CW) optical field propagating in the fiber with normal dispersion, and introduce a distinctive spectral evolution that differs from the previous … 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 …
WebJul 16, 2024 · Coded aperture correlation holography (COACH) combines incoherent digital holography with coded aperture imaging. COACH is also a method to record incoherent digital holograms of three-dimensional object scenes. Still, COACH can be used for several other incoherent and coherent optical applications. In this chapter, we survey the prime … Web2 days ago · In the age of information explosion, the conventional optical communication protocols are rapidly reaching the limits of their capacity, as almost all available degrees of freedom (e.g., wavelength, polarization) for division multiplexing have been explored to date. Recent advances in coherent mode division multiplexing have greatly facilitated high …
