Latest Patents

Yi-Shin Chan's latest patents focus on innovative methods for measuring the absorption coefficient and the reduced scattering coefficient of multiple scattering media. One of his patents describes a method where a source light beam is transformed into a mutually parallel circularly polarized photon pair. This transformed light beam is then split into a signal beam and a reference beam. The signal beam is projected into the multiple scattering medium, producing a diffused polarized photon pair density wave. The amplitude attenuation and phase delay of the signal beam are obtained through heterodyne interference signals, allowing for the inference of the medium's optical properties.

Another patent outlines a method that utilizes a coherent light beam with linear polarized P and S wave components. This coherent light beam is split into a signal beam and a reference beam, which are then projected into the medium. The optical interference signals are detected and converted into heterodyne interference electrical signals. By comparing these signals, Yi-Shin Chan's method allows for the inference of the absorption and reduced scattering coefficients at specific positions within the medium.
