Embodiment Construction

[0035] see figure 1 , the present embodiment is a star sensor optical system that can adapt to different orbits and different service life requirements, the system includes a first positive lens 1, a second positive lens 2, a first negative lens 3, an aperture 4, and a third positive lens 5. The fourth positive lens 6 and the second negative lens 7 . The first positive lens 1 , the second positive lens 2 , the first negative lens 3 , the diaphragm 4 , the third positive lens 5 , the fourth positive lens 6 and the second negative lens 7 are sequentially arranged on the same optical path 8 .

[0036] In order to better achieve ultra-long life, the first lens is made of JGS1 fused silica material with particularly good radiation resistance, and the rest of the lenses are made of radiation-resistant optical glass, so that the optical system can withstand high-energy radiation (such as gamma rays, x-rays and Under the action of cosmic rays), it has a certain stability against radi...

Abstract

The invention discloses a gravity center locating energy detection optical system with long service life, used for solving the problem that the traditional optical system is difficult to work stably and precisely for a long time in a severe electromagnetic environment. The optical system comprises a first positive lens, a second positive lens, a first negative lens, a diaphragm, a third positive lens, a fourth positive lens and a second negative lens which are sequentially arranged on the same optical path along an incident light direction, wherein all the six lenses are radiation resistant lenses which are made from fused silica material; and focal lengths, curvature radiuses and refractive indexes of the six lenses are designed and determined. The invention is particularly and suitably applied to long-life satellites with different space tracks, can woke for more than 10 years, and even for 25 years, is beneficial to correction of system aberration and has less defocused spots and color bias, favorable adaptability to environmental temperature and higher transmissivity.

Description

technical field [0001] The invention relates to a long-life center-of-gravity positioning energy detection optical system, which is mainly used in the occasions of long-life satellites in different space orbits, reactors, hot cells and various strong radioactive radiation. Background technique [0002] At present, in the field of aerospace, especially in the attitude control of high-orbit satellites, star sensors are needed to correct the flight path deviation of the probe, measure the attitude of the probe, and control the orientation of the solar panel and payload. , so as to ensure the stability of the orbit during the entire flight and ensure a certain flight attitude. For satellites in medium and high orbits, it is especially necessary to have a star sensor optical system that can be suitable for medium and high orbits for more than 10 years, and can even meet the 25-year service life requirements. Due to the harsh requirements of the working environment, the accuracy, ...
