Title: Qingsong Wang: Innovator in Optical Technologies

Introduction

Qingsong Wang is a notable inventor based in Lexington, MA (US). He has made significant contributions to the field of optical technologies, holding a total of 4 patents. His work focuses on advanced imaging systems that enhance subsurface inspection and spectral shaping.

Latest Patents

One of his latest patents is an optical coherence tomography (OCT) system designed for subsurface inspection. This OCT system incorporates a broadband light source and a beam splitter that divides the light into a reference beam and an illumination beam. The system includes a reference mirror that reflects the reference beam, while illumination optics pass the illumination beam through a reflective surface with optical power. The collection optics are configured to redirect the illumination beam to a sample surface, allowing for scattering that forms a sample beam. This beam is then combined with the reference beam to generate spectral interferometric information, which is processed to extract details about the sample.

Another innovative patent by Qingsong Wang is a spectrally shaped light source. This device generates a round beam that is transformed into a rectangular beam by an optical element. An image-forming dispersive device disperses the wavelengths and images the rectangular beam at a modulation plane. A pixelated spatial light modulator (SLM) is illuminated by the dispersed wavelengths, allowing for selective reflection of portions of the optical beam to achieve a desired spectral shape.
