Spatial Heterodyne Spectrometer Assembly Patented

Photonics Spectra
Oct 2009
Dr. Christoph R. Englert, a space scientist at the Naval Research Laboratory in Washington, has been awarded a patent by the US Patent and Trademark Office for his compression assembly design for spatial heterodyne spectrometer interferometer applications. The methods can be used for high-resolution space- and ground-based spectroscopy of diffuse sources, including atmospheric emissions or trace gas absorptions. The system is cost-efficient and robust, and it provides design flexibility with the option of various spacer materials.

An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. Interferometers are used extensively for testing optical elements during manufacture. Typical designs include the Michelson, Twyman-Green and Fizeau interferometers. The basic interferometer components are a light source, a beamsplitter, a reference...
