Crosscutting Spectrometer Advancement: High Throughput, Multi-Octave Imaging Spectrometer (CC-Spec)

Completed Technology Project

Project Introduction

Overarching objective: Research, design and develop a prototype of a new type of high-throughput, multi-octave imaging spectrometer that uses JPL unique capabilities.

This is a three year effort with the first year devoted to assessing and selecting the optimal approach to deliver a new high-throughput, multi-octave imaging spectrometer design architecture with laboratory demonstration.  At this time the initial technical approach is to explore use an innovative tuned-prism based imaging spectrometer design.  The concept is a Dyson imaging spectrometer with a tuned-prism as the dispersing element rather than a grating.  This plausible, but very challenging architecture would be original.  The effort will work to incorporate NASA unique and advanced technology including cryocoolers and detector arrays.  The multi-octave design will be compatible with the VSWIR 380 to 2500 nm range (~ 2.5 octaves) and the MLWIR range 2.5 to 15 microns (~ 2.5 octaves).
