WebOct 7, 2024 · Water-based coherent detection of broadband terahertz (THz) wave has been recently proposed with superior performances, which can alleviate the limited detection bandwidth and high probe laser... WebOct 28, 2006 · Incoherent detection also means that the modulation format is restricted to be only one of two basic forms; intensity or polarization modulation. A 1.6 kHz optical filter is virtually impossible to construct, so we can eliminate this approach to filtering for achieving the ultimate SNR.

WebThis method uses the analysis of low-frequency fluctuations (0–10 Hz) of optical signals reflected from tissues initially emitted by an incoherent source—an LED. The optical sensor of the prototype device uses three LEDs operating in the 560–580 nm wavelength range and one silicon photodiode.
