Imaging zoom for wide field-of-view imaging spectrometer

摘要

An imaging system comprises a wide field of view (FOV) telescope, a narrow FOV telescope, a spectrometer, an imaging detector, an image slicer, and a selection mechanism. The wide FOV telescope is configured to produce a one-dimensional optical image of a broad field of view (FOV) F. The narrow FOV telescope is configured to produce a two-dimensional optical image of a narrow FOV f. The spectrometer is configured to produce a spectrum of a one-dimensional image, and the imaging detector is configured to capture that spectrum. The image slicer is configured to break the two-dimensional optical image into a series of one-dimensional segments. The selection mechanism operable in either of two modes: a wide FOV mode transmitting the one-dimensional optical image to the spectrometer, and a zoom mode transmitting a one-dimensional concatenation of the series of one-dimensional segments to the spectrometer.

1. An imaging system comprising:
a wide field of view (FOV) telescope configured to produce a one-dimensional optical image of a broad FOV F; a narrow FOV telescope configured to produce a two-dimensional optical image of a narrow FOV f; a spectrometer configured to produce a spectrum of a one-dimensional image; a slit straightener configured to condition the output of the wide FOV telescope for reception at a straight input slit of the spectrometer; an imaging detector configured to capture the spectrum; an image slicer configured to break the two-dimensional optical image into a series of one-dimensional segments; and a selection mechanism operable in either of two modes: a wide FOV mode transmitting the one-dimensional optical image to the spectrometer, and a zoom mode transmitting a one-dimensional concatenation of the series of one-dimensional segments to the spectrometer.
