Introduction
Tong Chen is a prominent inventor based in Palo Alto, California, known for his significant contributions to technology and engineering. With a total of 12 patents to his name, he has made remarkable advancements in various fields, particularly in velocity measurement systems and traveling wave amplifier circuits.
Latest Patents
One of Tong Chen's latest patents is a velocity measuring system that utilizes a laser Doppler velocimeter. This system employs self-mixing amplification of backreflections from scatterers below the surface of a flow. The time domain signal is divided into segments that correspond to the transit time of particles through the focus of a laser beam. These segments are then connected to the frequency domain using an FFT algorithm to produce frequency domain data segments. The signal-to-noise ratio is enhanced through signal processing techniques, resulting in a final enhanced signal spectrum.
Another notable patent is related to asymmetrical slow wave structures designed to eliminate backward wave oscillations in wideband traveling wave tubes. This invention discloses a traveling wave amplifier circuit that receives an RF wave and an electron beam. The circuit facilitates synchronized interaction between the RF wave and the electron beam. It comprises a waveguide with a series of asymmetric cells arranged periodically, each containing at least one asymmetrical structure to modify the dispersion relation of the waveguide.
