Design of pushbroom imaging spectrometers for optimum recovery of spectroscopic and spatial information
TLDR
A modulation transfer function-based optimization method is described that generates optimal spectral and spatial uniformity of response from compact pushbroom imaging spectrometer designs.Abstract:
A modulation transfer function–based optimization method is
described that generates optimal spectral and spatial uniformity of
response from compact pushbroom imaging spectrometer designs. Such
uniformity is essential for extracting accurate spectroscopic
information from a pushbroom imaging spectrometer for Earth-observing
remote sensing applications. Two simple and compact spectrometer
design examples are described that satisfy stringent uniformity
specifications.read more

TL;DR: The Ocean Portable Hyperspectral Imager for Low-Light Spectroscopy (Ocean PHILLS) is a hyperspectral imager specifically designed for imaging the coastal ocean that uses a thinned, backsideilluminated CCD for high sensitivity and an all-reflective spectrograph with a convex grating in an Offner configuration to produce a nearly distortionfree image.

Spectral Calibration Requirement for Earth-Looking Imaging Spectrometers in the Solar Reflected Spectrum
TL;DR: A sensitivity analysis has been completed for imaging spectrometers with contiguously sampled spectral channel response functions and establishes that a spectral calibration accuracy approaching 1% of the full width at half-maximum throughput of the spectral response function is necessary to suppress errors in the measured radiance spectrum.

Convex diffraction grating imaging spectrometer
TL;DR: In this article, a 1:1 Offner mirror system for imaging off-axis objects is modified by replacing a concave spherical primary mirror that is concentric with a convex secondary mirror with two concave spheres of the same or different radii positioned with their respective distances d1 and d2 from a concentric convex spherical diffraction grating having its grooves parallel to the entrance slit of the spectrometer.
