Title: Innovations by Chong Chang Mao
Introduction
Chong Chang Mao is an accomplished inventor based in Plano, TX (US). He holds a total of 2 patents that showcase his expertise in advanced technologies. His work primarily focuses on semiconductor devices and holography, contributing significantly to the fields of sensing and imaging.
Latest Patents
One of his latest patents is a **Semiconductor Laser Based Sensing Device**. This innovative system determines the distance to a target object or its displacement by monitoring the electrical characteristics of a semiconductor laser aimed at the object. The light emitted from the laser reflects off the object's surface and returns to the laser, affecting its electrical characteristics. This relationship allows for accurate distance measurement and displacement detection. Additionally, the system can include an optical detector array, enhancing its capability to monitor multiple semiconductor lasers arranged in various configurations.
Another notable patent is the **Programmable Hologram Generator**. This device features a layered structure that includes a pixelated VLSI chip, a reflective ferroelectric liquid crystal, and a photorefractive crystal. The VLSI chip, controlled by a computer, stores holograms digitally. The reflective state of the liquid crystal's pixels is manipulated by the computer, allowing for the creation of desired holograms through interference with reference beams.
