Abstract

This Small Business Innovation Research (SBIR) Phase II project focuses on the commercialization of multichannel holographic spectrometers featured large operating bandwidth and fine spectral resolution. The proposed research is to develop a new platform for spectrometers using multiplexed cylindrical beam volume holograms (MCBVHs) as dispersive elements. Due to its unique characteristic, the MCBVH enables the design of two-dimensional (2D) spatial-spectral output patterns to significantly enhance the functionality of holographic spectrometers. A significant improvement of the operating bandwidth can be achieved without sacrificing spectral resolution while keeping all merits of a compact, lightweight, low-cost, reliable, and alignment robust holographic spectrometer. With the proposed multichannel spectrometer, several species of interest can be detected at one shot even though their spectrums are distributed in a very large spectral bandwidth. Due to the design flexibility of volume holograms, this technology enables the design of spectrometers with custom functionalities. Breaking the resolution-bandwidth trade-off of the conventional spectrometers with a holographic system that does not increase the complexity of the final product is the major breakthrough expected from this project. The expected outcome of this project will be a simplest yet highly functional spectrometer that can be designed to perform for technically any given application criteria.
