Title: Innovations by Yunmiao Wang in Fiber Optic Sensor Technology
Introduction
Yunmiao Wang is a notable inventor based in Houston, TX, specializing in advancements in fiber optic sensor technology. With a total of 4 patents to his name, he has made significant contributions to the field, particularly in the oil and gas industry.
Latest Patents
One of his latest patents is a method to compensate for measurement errors of fiber Bragg grating sensors caused by hydrogen darkening. This innovative method addresses the challenges faced by fiber Bragg grating (FBG) sensors installed in down-hole oil and gas environments. The process involves loading a fiber of known length and multiple FBG sensors in a hydrogen chamber while controlling temperature, hydrogen concentration, pressure, and time. By adjusting these variables through a test matrix and continuously measuring fiber transmission loss and FBG spectrum changes, a correlation map is created. This map is then utilized to compensate for the wavelength shift of downhole installed fiber cables as a function of their hydrogen-induced transmission loss over time.
Another significant patent by Wang involves methods to correct spectrum distortion of fiber Fabry-Perot interferometric (FFPI) sensors induced by dynamic wavelength-dependent attenuation. These methods propose measurement techniques that correct the reflective spectrum from one or more FFPI sensors by utilizing a background low-frequency spectrum for normalization. This innovation is crucial for enhancing the accuracy of measurements in subsurface wells.
