Distributed Acoustic Sensing for Passive Ranging Optical Computing Device Having Detector With Non-Planar Semiconductor Structure

摘要

An optical computing device including a detector having a non-planar semiconductor structure is provided. The detector may include one or more structures having structure characteristics that may be optimized to respond to and weight predetermined wavelengths of light radiated from a sample that are related to characteristics of the sample. The detector may include an array of the one or more structures, wherein each of the structure units may be individually addressable to program or tune the detector to respond to and weight a spectra of light and generate an output signal based on the weighted spectra of light that is proportional to the characteristics of the sample.
