Latest Patents
One of Xiaobai Sun's latest patents is related to compressive sampling and signal inference. This invention involves an optical wavemeter that includes a slit, a diffraction grating, a mask, a complementary grating, and a detector. A monochromatic source is incident on the slit, and the diffraction grating produces an image of the slit in an image plane that varies with wavelength. The mask features a two-dimensional pattern of transmission variations, generating different vertical intensity channels for various spectral channels. The complementary grating creates a stationary image of the slit that is independent of wavelength. The detector measures vertical intensity variations of this stationary image, and the mask is designed so that the number of measurements made by the detector is less than the number of spectral channels sampled.
Another notable patent by Xiaobai Sun involves compressive sampling of an optical signal. In this invention, an optical component is created with multiple transmissive and opaque elements. The arrangement of these elements is determined by a transmission function. The optical signal's spectrum is dispersed across the component, and signals from the transmissive elements are detected simultaneously at each sensor in a spatially distributed array. This method allows for the calculation of estimated optical signal values from the measurements, with the transmission function ensuring that the number of measurements is less than the number of estimated values.
