Embodiment
The present invention presses Fig. 1 structure shown in Figure 2 and implements, and Fig. 1 and Fig. 2 comprise tungsten lamp seat 1, tungsten lamp 2, condenser 3, optically focused microscope base 4, simulation slit 5, simulation slit base 6, plane mirror 7, plane reflection microscope base 8, first concave spherical mirror 9, the first concave spherical mirror seat 10, protruding spherical reflector 11, protruding spheric reflection microscope base 12, second concave spherical mirror 13, the second concave spherical mirror seat 14, instrument base 15, beam splitter mount pad 16.Tungsten lamp 2 adopts the tungsten lamp of 24V50W to be contained on the tungsten lamp seat 1 that steel plate does, tungsten lamp seat 1 and condenser 3 all are contained on the instrument base 15, adjust the position of mirror condenser 3, light is evenly thrown light on simulate slit 5, simulation slit 5 is graticules of a dark background, light seam, be carved with at interval three photoetching slit a of accurate simulation visual field, b, c on it as shown in Figure 2, the a seam is the simulation light slit of visible and near infrared spectrum instrument slit, the b seam is the simulation light slit of short-wave infrared spectrograph slit, and the c seam is the simulation light slit of full color imaging instrument image planes.The precision of simulation slit 5 is vital, the whether accurate adjustment precision that directly influences visual field beam splitter of the relative position between them.Three of slit 5 seams of simulation are wide to depend on visible and near infrared spectrum instrument slit, the short-wave infrared spectrograph slit of visual field beam splitter, the width of PAN detector image planes.The interval determination of simulation slit 5 visual field beam splitter the visual field at interval, its selection is moderate.At first the visual field at interval can not be too big, and the visual field is crossed conference at interval and increased opening of the telescope, causes increasing telescopical volume.Owing to the influence of vehicle yaw and earth rotation, excessive visual field also can increase the pixel number that can not mate at interval simultaneously; On the other hand, the visual field at interval can not be too small, because will place two edge of a knife catoptrons, two slits and full color imaging instrument focal plane component in visual field separation place, the visual field interval too small brings very big difficulty can for these element design, manufacturing.Comprehensive two aspect factors are got the visual field and are spaced apart 1.4mm.Therefore, the interval of simulation slit also just is defined as 1.4mm ± 0.002mm.
Because simulation slit 5 is positioned at focal plane, the any small defect of simulation on the slit 5 all by system imaging on detector, be the degree of accuracy that guarantees that the visual field is separated, every error requirements strictness of three slits, stitching wide error 0.002mm, the depth of parallelism is 0.001mm, the slit edge is straight, and clear local defect is not more than 0.5 μ m.Plane reflection microscope base 8, the first concave spherical mirror seat 10, protruding spheric reflection microscope base 12, the second concave spherical mirror seat 14 are all processed with Birmasil, all be screwed respectively on instrument base 15, beam splitter mount pad 16 also is installed on the instrument base 15 at focal plane place, picture side.After mixing up optical position, beat the pin location.Instrument base 15 adopts Birmasil processing, and each optical module all is installed on the same plane of base, and by given benchmark, the installing and locating hole of disposable each optical module of Precision Machining.The screw hole of each optical module base is processed into elongated hole, so that the adjustment location, position of each optical module.
