Minimum Resolvable and Minimum Detectable Contrast Prediction for Monochrome Solid-State Imagers

Research on Minimum Resolvable Contrast of the Telescope

“…The concept of minimum resolvable contrast(MRC) as applied to TV cameras, although analogous to minimum resolvable temperature difference(MRTD) for thermal imagers, appears to be less well established, despite its usefulness as an input to modeling of sensor field performance. At present, the research on the minimum resolvable contrast is limited to the simple imaging system, or the imaging devices, and mainly limited to the method of measurement in laboratory [10][11], the research on minimum resolvable contrast of the telescope hasn't developed. Based on the imaging process of the telescope and the detecting SNR, noise equivalent contrast is put forward, then combined with the system MTF, the model on minimum resolvable contrast of the telescope is build.…”
