Abstract
The present invention relates to a design of an optical path shift-in mechanism for a spatial optical spectrum instrument, which mainly comprises a lower diffuse reflector 1, an upper diffuse reflector 2, a shaft 3, a stopping seat 4, a conical pin 5, a pinion 6, a stopping screw 7, a big gear 8, a motor 9 and a control system 10. Both of the diffuse reflectors are used for adapting the factor that the reflectance ratio of the diffuse reflectors are influenced by surface cleanness and vacuum environment under the space environment, and the reflectance ratio variation of the diffuse reflectors can be monitored. The diffuse reflection surface of the upper diffuse reflector is protected by the back surface of the diffuse reflectors via an overlapped form design of the two diffuse reflectors. Simultaneously, the two diffuse reflectors are controlled to rotate respectively by a U-shaped slot 11 on the stopping seat and respectively come into the operation state. Consequently, the reflectance ratio variation of the two diffuse reflectors can be compared to improve the performance index of the spatial optical spectrum instrument. The present invention can be used in the technical fields of spaceflight and avigation, and can also be used for some specific environments and conditions.
Description
Technical field:
The present invention relates to the spectral instrument technical field, particularly relate to a kind of design that spatial spectral instrument light path moves into mechanism that is applied to.
Technical background: diffuse reflector is an optical element important in the spectral instrument radiation calibration, in numerous spectral instruments, only adopts a diffuse reflector mechanism, mainly comprises: diffuse reflector, train of reduction gears, stepper motor etc.By the step motor drive train of reduction gears, change the corner of diffuse reflector through train of reduction gears.Because the reflectivity of diffuse reflector is affected by environment bigger, therefore not only to keep its surface cleaning, but also will monitor the reflectance varies of diffuse reflector, thus the complete machine performance index of assurance spectral instrument.
To being applied to the spectral instrument on ground, the variation of diffuse reflector reflectivity can be adopted and change diffuse reflector and monitor, and can monitor like this because diffuse reflector surface cleanliness and be subjected to vacuum environment to influence the reflectance varies of being brought.But to being applied to the diffuse reflector of spatial spectral instrument, can not change by the actual environment constraint, therefore can't monitor, thereby influence the complete machine performance index the reflectance varies of diffuse reflector.
Summary of the invention:
Be applied in order to solve background technology that the diffuse reflector reflectance varies is influenced by surface cleanliness and vacuum environment easily in the spatial spectral instrument, make the reflectance varies of diffuse reflector can't problems of monitoring, the object of the invention provides a kind of double diffuse reflection apparatus that can monitor space diffuse reflector reflectance varies.
The present invention utilizes the light path at spectral instrument to move into two diffuse reflectors of mechanism's installation.Two overlapping installations of diffuse reflector but do not contact with each other, one is used once in a while, and one is often used, and can be used for monitoring the variation of space diffuse reflector reflectivity like this with two diffuse reflectors contrasts.Mechanism of the present invention comprises: following diffuse reflector, last diffuse reflector, axle, limit base, taper bolt, pinion wheel, stop screw, gear wheel, motor and control system.
One end of last diffuse reflector places down in the groove of diffuse reflector, and will descend diffuse reflector and last diffuse reflector to link together by axle, limit base is fixedlyed connected with following diffuse reflector with axle, taper bolt is fixedlyed connected with pinion wheel with axle, stop screw places on the pinion wheel, and the end of stop screw contacts with the U-lag of limit base, gear wheel and pinion, motor is fixedlyed connected with gear wheel, and control system is connected with motor.
Structure of the present invention drives axle by motor by pinion wheel and gear wheel, thereby diffuse reflector turns to design attitude in the drive, and when using diffuse reflector, connect pinion wheel by stop screw, stop screw screws in the U-shaped stopper slot of limit base, stopper slot is connected with following diffuse reflector, make the rotation of diffuse reflector down be subjected to the constraint of U-shaped stopper slot on the limit base thus, when last diffuse reflector moves to assigned address, motor continues to drive, when pinion rotation arrived the stop screw place, stop screw just drove diffuse reflector rotation down like this, and upward diffuse reflector also is rotated further, turn to assigned address up to following diffuse reflector, by control system one of two diffuse reflector are used once in a while, one is often used, has so just realized the rotating function of double diffuse reflection apparatus.
Characteristics of the present invention: adopt double diffuse reflection apparatus to adapt to the influence factor that diffuse reflector reflectivity under the space environment is subjected to surface cleanliness and vacuum environment, can monitor to the reflectance varies of diffuse reflector.Eclipsed form design by two diffuse reflectors; make the diffuse reflection surface of going up diffuse reflector be got up by the back-protective of diffuse reflector; drive diffuse reflector rotation down by U-shaped stopper slot on the limit base and stop screw simultaneously and enter duty immigration light path; and make diffuse reflector shift out light path; two one of diffuse reflectors use once in a while; one is often used; and then can contrast the reflectance varies of two diffuse reflectors; reflectivity to diffuse reflector after data are sent to ground is revised, thereby improves the performance index of spatial spectral instrument.The present invention can be used for space flight and aviation technical field and some special environment conditions.
