Dynamically big visual field little distortion star simulator optical system also comprises diaphragm 1, and diaphragm 1 and the 5th positive lens are arranged on the same light path.
PBS, first negative lens and first positive lens are set in turn on the same optical axis.
Star simulator in the past all adopts the built-in or diaphragm of diaphragm to be positioned at the structure of certain piece lens frame, and this system stop is arranged on outside the optical system, helps and the shared diaphragm of system under test (SUT); In addition; This optical system is when design; With the 4th original lens, be divided into two lens (being exactly the 3rd positive lens and second negative lens among the present invention), increased the variable parameter of design; And then improved optical system greatly under the prerequisite of big visual field, long-focus, good imaging picture element is still arranged.Consider that total system requires high simulation precision is arranged, and can simulate bigger sky district, so when the whole star simulator optical system of design, adopt the mode that LCOS optics splices to guarantee that this system has bigger linear field in image planes.This design, it is low to have changed traditional image planes employing LCD or TFT simulation precision, and the little defective of target surface linear field.The design of Optical System scheme of this star simulator is as shown in Figure 2, and star simulator device design concept is as shown in Figure 1.
As shown in Figure 2, when star sensor is tested, the optical axis and the star simulator optical axis of its star sensor transferred to parallel, promptly the diaphragm of star simulator overlaps with the entrance pupil of star sensor.
The dynamic star simulator in wherein big visual field mainly is made up of: star simulator directional light optical system 2, uniform source of light 11, PBS12, a LCOS13, the 2nd LCOS14, star chart control and light source controller 16.
Principle of work is: Fig. 2 is a high precision, big visual field parallel light tube, and this optical system is an asymmetric diaphragm external structure; As required, on the static star simulator optical system of Plossl formula, retrofit, its 4th positive lens 3 is divided into two positive and negative combination of lensess, such combination can make the 4th power of lens diminish, and reduces the introducing of senior aberration to a certain extent; In addition, positive and negative combination of lenses to a great extent correcting chromatic aberration to the influence of whole optical system.This optical system has advantages such as big visual field, long-focus, little distortion compared with star modular system in the past.During work; Light by the asterism at the parallel light tube place sends sends a branch of directional light behind the parallel light tube collimation, star sensor optical system 7 is taken facing to its emergent pupil; A width of cloth star chart picture can be formed at image planes 5 places of star sensor, and then the reliability of star sensor optical system 7 can be demarcated.
The concrete principle of work of system is: the light that sends by uniform source of light 11 through 10 of polaroids partially after; Arrive the lower surface of PBS12; PBS12 is divided into P light and S light with light again, and wherein S light is reflected, and arrives on the LCOS13 through quarter wave plate 15; Get on the 2nd LCOS14 on P light transmission PBS12 and another piece quarter wave plate 15, can illuminate two LCOS (LCOS after illuminating can reflex to respectively in the star mould device optical system 2 playing bright star chart) this moment simultaneously; Then through star chart control and light source controller 16 adjustable light source illumination and the control simulation star chart in district on the same day not, thereby make the luminance brightness of LCOS surface reflection and simulation star chart satisfy not the star in district simulation requirement on the same day.Because this star simulator requires Da Tian district star chart of simulation; When design; This star simulator directional light optical system 2 is selected big visual field parallel light tube system for use, and its image planes are of a size of Φ 24mm, and general LCOS image planes size is so big; Event need select for use two LCOS to carry out the optics splicing, and the splicing scheme is as shown in Figure 1.This moment, two LCOS laid respectively at the conjugate focal planes place of star simulator optical system; If illuminate LCOS through light source; Then send a branch of directional light in star simulator directional light optical system 2 exits; Look facing to the system optical axis direction, as starlight radiation from infinite distant place, i.e. the dynamic principle of work of star simulator.Wherein the function of each several part is introduced as follows:
Uniform source of light 11 is mainly in order to provide the simulation star chart luminous luminous energy.The effect of polaroid 10 is that the light that light source is sent becomes P light and S light.The effect of PBS12 is to make light by beam split, i.e. P light transmission PBS12, and S light is reflected at light splitting surface, goes and propagates into the orthogonal light of two bundles.The main effect of two quarter wave plates 15 is to make the P light and the S light that incide the LCOS surface are modulated into S light and P light respectively.The effect of two LCOS is to make to incide its surperficial light and beat bright star figure control and light source controller 16, then star chart control and light source controller 16 is reflexed in the star simulator directional light optical system 2, realizes the star image simulation of star simulator; In addition, adopting the effect of two LCOS is in order to realize the optics splicing of large visual field optical system image planes.What collimating optical system adopted is large visual field optical system, and the picture element of this system is good, and distortion is less than 0.05%, and center of energy and chief ray position deviation are less than 8 ", optical system collimation precision is superior to 10 "; Collimating optical system mainly is in order to simulate the asterism radiation of infinite distant place.Star chart control and light source controller 16 mainly are the variations that realizes not distinguishing on the same day star chart through computer control unit, and the spoke brightness size of control light source is simulated the characteristics of luminescence of different magnitudes.
The invention difficulty of this star simulator is the design of star simulator directional light optical system 2 and the splicing of big visual field LCOS.Fig. 1 is the design result of this star simulator directional light optical system 2; It has solved the design contradiction of big visual field and little distortion; Designed the big visual field of a kind of asymmetric diaphragm external collimating optical system (this system stop and star sensor diaphragm are shared); Wherein distortion, aberration, disc of confusion diameter, collimation precision, center of energy and chief ray position deviation all satisfy request for utilization, have good picture element.In addition, adopt two LCOS to realize the big field stitching of optical mode among Fig. 2, the employing of this method has remedied the too little defective of existing device size, has breakthrough innovation.
