Design of an ultra-broadband, wide-field-of-view push-broom imaging radiometer

Abstract

The design of a push-broom radiometer operating from 0.2 μm to greater than 50 μm with a FOR > 120° is presented. The challenge is to design a WFOV radiometer with high accuracy and low uncertainty. This paper will present the results of an effort to design an ultra-broadband WFOV imaging radiometer, while balancing conditions that can impact the radiometric accuracy of the instrument. This system is further complicated by implementation of a single detector array that is sensitive to light over this very broad spectral range.
