We have fabricated and tested a multi-beam light source using an optical waveguide. It had an optical output of 12 mW with a propagation efficiency of 30%. The crosstalk between neighboring channels was -17.69 dB. When the output power was increased from 0.5 to 10 mW, the wavefront aberration fell to less than /spl lambda//20. As a result, even when the(More)
Introduction: KAGUYA(SELENE) is the most sophisticated lunar exploration mission in the post-Apollo Era and consists of the main orbiter and two small satellites – the Relay satellite (OKINA) and the VRAD satellite (OUNA). SELENE was successful launched on September 14, 2007 at Tanegashima Space Center of JAXA and it was entered polar orbit with about 100km(More)
Japan's first large lunar explorer was launched by the H-IIA(JST). This explorer named " KAGUYA (SELENE: SELenological and Engineering Explorer) " has been keenly anticipated by many countries as it represents the largest lunar exploration project of the post-Apollo program. The lunar missions that have been conducted so far have gathered a large amount of(More)
