Introduction

Zhen Chen is an accomplished inventor based in Kingstown, Rhode Island. He has made significant contributions to the fields of strain measurement and laser technology, holding a total of four patents. His innovative work has the potential to enhance various applications in sensing and measurement.

Latest Patents

One of Zhen Chen's latest patents is a coaxial cable sensor device for distributed strain measurement and shape sensing applications. This invention provides a novel distributed coaxial cable strain sensor that can measure a strain profile over the entire length of a cable. Individual strain sensing elements are constructed using Fabry-Perot interferometers, coaxial cable Bragg gratings, or other reflectometry-based sensing structures. By assembling three or more strain sensors together in a bundle, a coaxial cable shape sensing device can be constructed, capable of accurate three-dimensional position measurement.

Another significant patent is the method and apparatus for coherence enhancement of sweep velocity locked lasers via all-electronic upconversion. This invention offers methods and apparatus to improve the dynamic coherent length of a sweep velocity-locked laser pulse generator in an all-electronic fashion. A digital sweep velocity-locked laser pulse generator is disclosed with two operation modes: unidirectional and bidirectional sweep modes. The invention includes self-adaptive and time-dependent loop parameters, as well as high-frequency locking architectures to suppress linewidth and improve coherent length. The enhanced laser coherence extends the measurement range significantly for applications such as frequency-modulated continuous wave light detection and ranging and optical fiber distributed sensing.
