Research Abstract

I developed a new algorithm for analyzing the spectral data from Spectral Profiler (SP) onboard the Japanese lunar satellite Kaguya. The SP data covers the wavelengths of visible-near infrared and provide the valuable information about the mineral distribution on the Moon. To retrieve the mineral information from the SP data, we need to detect and quantify the features of absorption band of the observed spectra. By using my optimized algorithm, we can automatically analyze all the SP data covering the whole Moon which amounts to about 70 million points of observation.
