Earth Observing-1 Advanced Land Imager: Dark Current and Noise Characterizationand Anomalous Detectors

摘要

The dark current and noise characteristics of the Earth Observing-1 Advanced LandImager measured during ground calibration at MIT Lincoln Laboratory are presented. Data were collected for the nominal focal plane operating temperature of 220 K as well as supplemental operation temperatures (215 and 225 K). Dark current baseline values are provided, and noise characterization includes the evaluation of white, coherent, low frequency, and high frequency components. Finally, anomalous detectors, characterized by unusual dark current, noise, gain, or cross-talk properties are investigated.
