Title: Innovations of Hang Zhao in Virtual Sensor Technology

Introduction

Hang Zhao is an accomplished inventor based in Cambridge, MA, known for his innovative contributions to the field of imaging technology. He has developed a unique patent that enhances the capabilities of time-of-flight cameras, allowing them to capture images of objects that are not directly visible.

Latest Patents

Hang Zhao holds a patent for "Methods and apparatus for virtual sensor array." This invention enables a time-of-flight camera to image an object around a corner or through a diffuser. In scenarios where imaging occurs around a corner, light from a hidden target object reflects off a diffuse surface and travels to the camera. The points on the diffuse surface act as virtual sensors. Conversely, when imaging through a diffuser, light from the target object is transmitted through a diffusive medium to the camera. The visible points on the surface of the diffusive media also function as virtual sensors. In both cases, a computer processes phase and intensity measurements taken by the camera, representing them as a system of linear equations. This allows for the recovery of an image of the target object or the computation of a 3D position for each point on the exterior surface of the target object.
