Paper Abstract

The Multi-Spectral Camera (MCS) is the electro-optical imaging isntrument for high-resolution observation of the Earth with push broom scanning in the space. The MSC uses compact and light weighted optical design to tkae image with high MTF (modulation transfer function) performance. The Ritchey-Chretien with focal correct lens is selected to implement enough performance in the wide swath width. The focal plane has one panchromatic (PAN) and four multi-spectral (MS) CCD (charge coupled device) for the imaging of visible and near-infrared wavelength. The PAN and MS have their own focus correct lens to correct field aberration and also to make proper effective focal length. Here we present the optical design and analysis of the MSC.
