Title: Innovations of Chuan Yang
Introduction
Chuan Yang is a notable inventor based in State College, PA (US). He has made significant contributions to the field of optical technologies, holding 2 patents that showcase his innovative approach to imaging and spectroscopy.
Latest Patents
One of his latest patents is focused on Z-microscopy. This method presents a novel approach for parallel axial imaging by utilizing an array of tilted micro mirrors arranged along the axial direction. The image signals emitted from different axial positions can be orthogonally reflected by the corresponding micro mirrors and spatially separated for parallel detection. This essentially converts the more challenging axial imaging into a lateral imaging problem. Each micro mirror also provides optical sectioning capability due to its finite dimension.
Another significant patent involves a compact spectrometer that includes a diffractive optical element with dual dispersion and focusing functionality. This invention, referred to as the 'G-Fresnel' device, performs the functions of both a linear grating and a Fresnel lens. The G-Fresnel device has been fabricated using PDMS-based soft lithography. Three-dimensional surface profilometry has been performed to examine the device quality, and optical characterizations have confirmed its dual focusing and dispersing properties. The G-Fresnel device can be beneficial for the development of miniature optical spectrometers and emerging optofluidic applications. Theoretical simulations indicate that a spectral resolution of approximately 1 nm can potentially be achieved with a millimeter-sized G-Fresnel. A proof-of-concept G-Fresnel-based spectrometer with subnanometer spectral resolution has been experimentally demonstrated.
