Tunable Light-guide Image Processing Snapshot Spectrometer (TuLIPSS) for Earth Science Research and Observation
type: Dataset
description: Objectives and Benefits We propose to develop and test a Tunable Light-guide Image Processing Snapshot Spectrometer (TuLIPSS) for future implementation on UAV, airborne, and orbiting platforms. The proposed system, when fully operational, will be able to perform a wide variety of Earth remote sensing observations. Here we focus on the development of a high fidelity functional prototype to be flight-tested on an aerial platform by the end of the funded period. TuLIPSS will be capable of acquiring instantaneous images across the visible and near-IR, with a flexible spatial/spectral resolution tradespace. This is accomplished using custom-adaptable fiber optic image processing bundles whose input is in the form of a densely-packed coherent waveguide. The optical output from each waveguide, or line of waveguides, can be flexibly designated as spatial or spectral enabling a wide variety of observational configurations.. Thus, the system's innovative aspect is the controlled repositioning of pixels between the input and output of waveguide coherent structures, allowing efficient multi-dimensional (x, y, λ) snapshot imaging and operational flexibility. This flexibility enables a range of spatial/spectral configurations (e.g. specific sub-bands around target lines, prioritization of spatial or spectral resolution, etc.) to satisfy specific observational goals. Additionally, TuLIPSS is low resource (mass, volume, power) but highly capable. The ability to collect data across an entire scene in a single exposure makes TuLIPSS uniquely suited to a range of Earth science applications, including the ability to record transient surface and atmospheric phenomena, and to provide multiple views through an atmospheric column for tomographic studies. As proposed, TuLIPSS will allow: a) snapshot hyperspectral image acquisition and high light collection efficiency b) tunable adjustment of spatial and spectral resolution, and flexible selection of target wavelengths c) spectral coverage a…
