The optical communication experiment a the Communications Research Laboratory (CRL) in Japan has been performed using the engineering test satellite VI (ETS-VI) which was launched into a high elliptical orbit. The laser communication equipment (LCE) installed on the ETS-VI satellite can measure the radiation power from various areas on the earth like the sea, land and clouds. The LCE charge coupled device (CCD) sensor and quadrant detector (QD) sensor are used to obtain the spectral radiant emittance at a wavelength lambda equals 0.5 micrometers from the earth surface. This paper shows the results of the experiment to measure the background radiation.
