- Hyperspectral imaging refers to the measurement of data in a number of contiguous wavelengths. It has increasingly been used in remote sensing to obtain information about a scene in many applications ranging from vegetation analysis to aeronomy. The information obtained from optical methods can be spatial, temporal, spectral, polarimetric or a combination of these. An ideal and versatile instrument is one which can provide information in all four domains at high spectral resolution, and can be used for many applications with minimum modifications. In this work we present our first attempt at building such a hyperspectral imaging system called Liquid Crystal Hyperspectral Imager (LiCHI) which uses Liquid Crystal Fabry-Perot etalons. LiCHI has been built and tested for three applications, viz. auroral imaging, outlier detection and environmental or vegetation analysis. Preliminary measurements and analyses from these tests are presented here. The challenges posed by these applications for the design and performance of the system are discussed here.
