Testing and Analysis of Astronomical Applications for Self-reliant Domestic Infrared Detectors postprint

Abstract: Over the past two years, China has achieved significant breakthroughs in the development of infrared detectors. Guided by the demands of astronomical observation, we have conducted comprehensive tests on all astronomical detection parameters of the infrared detector and obtained key indicators such as readout noise, dark current, full well capacity, dynamic range, nonlinearity, nonuniformity, and quantum efficiency. These tests have enabled us to assess the detector’s capabilities in infrared astronomy. Additionally, we utilized the 1.56 m Telescope at the Shanghai Astronomical Observatory’s Sheshan site for real-world observations. These observations confirmed that the detector’s ground-based application performance is comparable to that of foreign detectors, indicating that China’s infrared astronomy has advanced to a stage where it can employ domestically developed infrared detectors for astronomical observations in specific near-infrared bands.
