Introduction

Geoffrey A. Walter is an accomplished inventor based in Santa Ynez, CA (US). He has made significant contributions to the field of spectrometry, holding a total of 4 patents. His work focuses on developing advanced systems that enhance the detection of narrow-band spectral features.

Latest Patents

One of his latest patents is for a high-resolution differential spectrometry system. This innovative system detects very narrow-band spectral features while providing much higher optical transmittance and signal-to-noise ratios than prior optical-filter-based spectrometer systems. The system utilizes a plurality of light detectors that detect light falling within respective wide wavebands. These wide wavebands have overlapping and non-overlapping portions, with one being the desired narrow waveband. The outputs from the detectors are processed to produce an output signal that includes substantially only the desired narrow waveband. In the preferred embodiment, the light detectors are implemented with a pair of optical detectors and respective optical interference filters. The filters have substantially identical cut-off wavelengths and cut-on wavelengths that are shifted with respect to each other. The detector outputs are differenced using an operational amplifier, allowing for the cancellation of signals resulting from spectral features common to both detectors. The remaining signal varies according to the amount of light that falls between specific wavelength boundaries. A preferred method of fabricating the optical interference filters is also provided in this patent.
