Abstract
The near-infrared spectrum of the diffuse emission was observed using a rocket-born printabs infrared telescope cooled by liquid helium with a newly developed charge integrating detection system. The observed sky brightness at high ecliptic and Galactic latitude is consistent with the previous result obtained by Matsumoto, Akiba, and Maurakami, and also with the early report from the Cosmic Background Explorer (COBE). The spectrum is generally smooth. The observed sky brightness seems to be dominated by zodiacal light, and the contribution of star light is negligible. The near-infrared spectrum of the derived zodiacal light is similar to the solar color. The total brightness, however, is significantly brighter than that expected from previous optical measurements of the zodiacal light. A possible interpretation of the observed spectrum is discussed.
