MULTI BACKEND ULTRA-BROADBAND DISPERSIVE SPECTROMETER

摘要

Various embodiments of systems and methods are described herein that can be used for obtaining large bandwidth, high resolution spectral images in a single snapshot by using multiple detection stages that operate in different wavelength ranges and are coupled in a branch-like fashion.

主权项

1. A system for detecting a light spectrum, wherein the system comprises:
an input configured to receive an input light beam; and a chain of detection stages coupled to one another in a branch-like fashion, each detection stage being configured to detect a dispersed spectrum over a certain detection wavelength range of light where a first detection stage in the chain of detection stages is coupled to the input to receive the input light beam and at least one given detection stage that is upstream of a final detection stage in the chain of detection stages is configured to perform detection on a first portion of dispersed light having wavelengths within the detection wavelength range of the at least one given detection stage and to direct a second portion of undispersed light to a downstream detection stage, the directed light having wavelengths outside of the detection wavelength range of the at least one given detection stage and wherein the at least one given detection stage comprises an optical element to receive a given light beam and separate the given light beam into the first portion of dispersed light and the second portion of undispersed light having different first and second wavelength ranges respectively.
