Title: The Innovative Contributions of Randall S. Geels

Introduction

Randall S. Geels is a prominent inventor based in San Diego, CA. He has made significant contributions to the field of optical instrumentation, holding a total of 8 patents. His work focuses on developing advanced systems that enhance measurement capabilities through innovative optical technologies.

Latest Patents

One of his latest patents involves an optical instrumentation system that includes a spatially variable filter. This system comprises a light source and a retention device designed to receive and retain a sample for measurement. The optical path couples light between the light source, the sample, and a detector. An optical objective is configured to direct light from the light source to the sample and to couple reflected light to the detector. Additionally, a controller is included to automatically manage the focus and beam path of the light directed to the sample. The spatially variable filter (SVF) within the optical path is designed to have spectral properties that vary based on the illuminated position on the SVF.

Another notable patent by Geels is an optical spectrometer configuration that also incorporates a spatially variable filter. This system is designed to illuminate a sample under measurement and includes a detector that receives reflected light from the sample. The detector generates a signal representing the reflected light, while the SVF is again positioned in the optical path, configured to have spectral properties that vary with the illuminated position.
