The Cosmic Infrared Background ExpeRiment (CIBER) is a rocket-borne absolute photometry imaging and spectroscopy experiment optimized to detect signatures of first-light galaxies present during reionization in the unresolved IR background. CIBER-I consists of a wide-field two-color camera for fluctuation measurements, a low-resolution absolute spectrometer for EBL measurements, and a narrow-band imaging spectrometer to measure and correct scattered emission from the foreground zodiacal cloud. CIBER-I was successfully flown on February 25th, 2009 and is expected to be flown three more times over the next two years at six month intervals. CIBER-II is a wide-field 30 cm imager operating in 4 bands between 0.5 and 2.1 microns. It is designed for a high sigma detection of unresolved IR background fluctuations at the minimum level necessary for reionization.With an etendue (a figure-of-merit for survey studies) a factor of 50 to 500 larger than existing IR instruments on satellites, CIBER-II will carry out the definitive study to establish the surface density of sources responsible for reionization.
