Abstract:
A spectral imaging system includes an autocorrelator to generate different autocorrelations when the moving reflector in the autocorrelator is at different positions so as to reconstruct spectral images. The system also includes a position measurement system to measure the actual positions of the moving reflector when autocorrelations are taken. These actual locations, instead of the desired locations in conventional methods, are then used to reconstruct the spectral image. This approach can address the misalignment of the moving reflector from its desired location (due to external disturbances, slow actuator dynamics, and other factors) in conventional spectral imaging techniques and allow the development of high-resolution, high-stability, portable imaging spectrometers for the general public.

Claim (Index 21):
A spectral imaging system comprising:\n an autocorrelator to create an autocorrelation pattern of an input light beam reflected or scattered from a sample, the autocorrelator comprising:\n a beam splitter to split the input light beam into a first portion and a second portion; \n a first reflector to reflect the first portion of the input light beam; \n a second reflector to reflect the second portion of the input light beam; and \n a detector, disposed at an intersection between the first portion of the input light beam and the second portion of the input light beam, to detect an autocorrelation pattern created by the first portion of the input light beam and the second portion of the input light beam; \n a positioning and measurement system operably coupled to the second reflector, the positioning and measurement system comprising:\n an actuator to place the second reflector at a plurality of positions non-uniformly spaced along a propagation direction of the second portion of the input light beam; \n a laser source to emit a probe laser beam toward the beam splitter, the beam splitter directing a first part of the probe laser beam toward the first reflector and directing a second part of the probe laser beam toward the second reflector; and \n an array of photodiodes, in optical communication with the first reflector and the second reflector via the beam splitter, to detect a probe interference pattern formed by the first part of the probe laser beam after reflection from the first reflector and the second part of the probe laser beam after reflection from the second reflector; and \n a processor, operably coupled to the autocorrelator and the positioning and measurement system, to estimate the plurality of positions of the second reflector based at least in part on the probe interference pattern and further to generate a spectral image of the sample based at least in part on the plurality of positions of the second reflector and the autocorrelation pattern of the input light beam.
