Abstract
This paper presents the advancement of the miniaturized optical telescope assembly (OTA) for exoplanetary astronomy and development of an ultra-sensitive detector system compatible with small satellite constraints. The test results have shown that the OTA achieves low PSF variations across wavelength and temperature ranges over a wide field enabling precision photometric observations of exoplanet transits candidates. The imaging performance and sensitivity of a compact detector compare favorably to that of ground-based Electron Multiplying CCD (EMCCD) and Complementary Metal-Oxide-Semiconductor (CMOS) imaging systems.
