Latest Patents

Yingzhong Shi holds a patent for a "Precision Tunable Optical Filter." This invention involves tuned optical filters, filter systems, and methods for tuning filters that utilize a tilted filter rotated about an oblique axis of a collimating lens or other structures. The rotation changes the angle of incidence of an optical signal directed at the filter at an oblique angle to the axis of rotation. This design allows for very fine adjustments of optical filters, enabling the tuning of a narrow band pass filter to match the center wavelength of another narrow band pass filter. The mechanical adjustment to the filtering frequency is enhanced by employing rotational motion about the axis of a GRIN collimating lens.
