Title: David Yue Yan: Innovator in Optical Measurement Technologies
Introduction
David Yue Yan is a prominent inventor based in Burnaby, Canada. He has made significant contributions to the field of optical measurement technologies, particularly in the development of devices that measure fluid velocities. With a total of 2 patents to his name, his work has advanced the capabilities of velocimeters and flow meters.
Latest Patents
One of David's latest patents is the "Optical Transit Time Velocimeter." This innovative device comprises a probe designed for insertion into a fluid, featuring an open area that allows fluid passage. The probe includes an illumination system that directs two light beams through the open area, along with a collection system that gathers forward scattered light from particles in the fluid. The electro-optical assembly connected to the probe measures fluctuations in the scattered light to calculate the fluid's velocity based on the lapse time and the separation distance.
Another notable patent is the "Optical Flow Meter for Measuring Gases and Liquids in Pipelines." This optical system is designed to measure the velocity of fluids flowing through pipes. It utilizes two beams delivered through a window in the pipe wall, focused at two points along the pipe's axis. By detecting light scattered by particles in the fluid stream, the system can determine the fluid's velocity by measuring the time delay between detected signals.
