30 results about "Infrared telescope" patented technology

An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum. All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation. In order to study the universe, scientists use several different types of telescopes to detect these different types of emitted radiation in the electromagnetic spectrum. Some of these are gamma ray, x-ray, ultra-violet, regular visible light (optical), as well as infrared telescopes.

Two mirror re-imaging telescope

An infrared telescope utilizes two mirrors in an off-axis, eccentric-pupil, re-imaging configuration. To improve the image quality of traditional two mirror telescopes, the reflective surfaces of both the primary and secondary mirrors are ellipsoidal. The ellipsoidal surface of the primary mirror has a greater eccentricity than the ellipsoidal surface of the secondary mirror. The infrared light entering through the eccentric pupil strikes the ellipsoidal reflective surface of the primary mirror. The light is reflected from the primary mirror to the ellipsoidal reflective surface of the secondary mirror. An intermediate image of the object being viewed is formed between the primary and secondary mirrors. The light is reflected from the secondary mirror to an image plane. An aperture stop is located between the secondary mirror and the image plane. The image plane is typically located within a cold shield, to reduce the likelihood that stray light will reach the image plane.
