Abstract

The demand for airborne remote sensing based on the Earth environment observation has been growing, motivated by the need to protect the Earth's environment. Attention has been focused on hyperspectral sensors as new type of Earth observation sensor for measuring the surface conditions from the air. The Japan Aerospace Exploration Agency (JAXA) has developed an LCTF hyper-spectral imaging spectropolarimeter with selectable plane of polarization which senses radiation in the 400-720 nm visible light wavelength band, and has constructed an airborne optical observation system based on the sensor. Flight evaluation of this sensor using JAXA's Beechcraft 65 research airplane has been continuing over the past few years, and this paper first outlines this flight evaluation. Next, we report on current aerial observations of water contamination in the rivers or lakes and the growth stages of crops are shown, with spectral images taken at various wavelengths and polarization angles presented as the analyzed results of flight experiment data. The flight experiments have confirmed that spectral images of targets with differing characteristics do indeed show different spectropolarimetric properties. Plans for future flight evaluations are also described. Finally it is concluded that the way has been paved for applying the visible light sensor to airborne remote sensing, aiming at the determination of surface conditions.
