Document Type and Number:
Japanese Patent JP2646981
Kind Code:
B2
Abstract:
PURPOSE:To simultaneously obtain ground-surface sight data and atmospheric observation data by converting the data into digital electric signals and outputting the electric signals in a multiplexing state. CONSTITUTION:In an atmospheric observation apparatus 1, light L1 from the ground surface is made incident to a scanning mechanism system 11 and only infrared rays L3 separated from the light L1 through a front-end optical system 12 are outputted to an atmosphere sensor signal processing section 14 through an atmosphere sensor 13. The section 14 outputs the infrared rays L3 to a multiplexer 3 as atmospheric observation data D1 after performing amplification, waveform shaping, and digitization on the infrared rays L3. In a CCD camera 2, on the other hand, a light condensing optical system 21 condenses light by performing electronic scanning and a CCD/signal processing section 22 outputs the condensed light to the multiplexer 3 as visual data D2 after performing amplification, waveform shaping, and digitization on the condensed light. The multiplexer 3 formats and multiplexes the data D1 and D2 as observed data and the observed data are transmitted from a satellite data bus 5 through a satellite interface circuit 4.
