Improved device for the reception of the radiating energy, in particular in the form of infrared rays

摘要

An improved radiation energy detecting system is disclosed. The system comprises a rotating scanning mirror reflecting energy radiating from objects in the field of view through a novel image derotating prism, providing optimum transmission modulation transfer and minimal dimension for packaging, and focusing optics onto a radiant energy detecting array. The detector converts the radiant energy to electrical signals representative of the impinging radiant energy for display processing.
