Abstract
The invention discloses a large space optical remote sensor composite light blocking plate, which belongs to the space optical remote sensing technology field. The light blocking plate comprises a light blocking substrate, a piece of light blocking cloth and a nylon hasp; the light blocking substrate is made of a carbon-fibre composite, and the surface of the substrate is coated with a black stray light elimination paint; the light blocking cloth is made of high-strength polyester fabrics or high-strength brocade fabrics, and the surface of the cloth is coated with a matt film layer; the light blocking substrate and the light blocking cloth are lapped together through the nylon hasp; and the nylon hasp is fixed on the light blocking substrate and the light blocking cloth. Because of using the light and soft light blocking cloth, the dynamics response is substantially reduced; the intensity requirement is reduced; and the intensity reliability is improved. The light blocking cloth is made of a kind of weaving material that has a low reflectivity, therefore, the performance of stray light elimination is greatly improved, and the signal to noise ratio of the remote sensor is lifted. At the same time, because the weaving material is lighter than the carbon-fibre composite in the same area, the quality of the whole light blocking plate is effectively reduce. The light blocking plate can be applied in structures like the light blocking plates of large optical devices or outer light shields.
Description
Technical field
The invention belongs to space optical remote technical field, the compound relating to a kind of large space optical sensor blocks tabula rasa.
Background technology
Light shield with block the important component part that tabula rasa is Optical Integrated Analysis of Space Remote Sensor system, it can carry out intuitively and effectively suppressing to the parasitic light of the earth from the sun, the moon or reflected sunlight, thus raising remote sensor signal to noise ratio (S/N ratio).Light shield with block tabula rasa and not only should have good eliminate stray light performance, to meet its functional requirement, also must have higher strength reliability, to guarantee completing of task.At present, space optical remote sensor light shield with block tabula rasa and mostly adopt thin-wall construction, its material mostly is carbon fibre composite.For small-sized remote sensor, this structure can meet request for utilization, for large-scale remote sensor, this large size, thin walled structure dynamic test and the dynamic response in satellite launch stage very large, easily cause screw junction stress to be concentrated, time serious, there will be fracture.Solution conventional at present has two kinds: one to be the wall thickness increasing screw junction, avoids stress to concentrate; Two is arrange gusset in relevant position, to improve its rigidity, reduces dynamic response.No matter adopt which kind of method, all must increase the weight of thin-walled workpiece, add the difficulty of processing of product simultaneously.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of large space optical sensor compound and block tabula rasa, this blocks tabula rasa lightweight, low-response, antiradar reflectivity, solves the dynamic response problems of too that large space optical sensor blocks tabula rasa.
The technical scheme that technical solution problem of the present invention adopts is as follows:
A kind of large space optical sensor compound blocks tabula rasa, and this blocks tabula rasa and comprises: block photopolymer substrate, block light cloth and velcro; Blocking photopolymer substrate adopts carbon fibre composite to make, its surface spraying black eliminate stray light paint; Block light cloth to adopt and high-strengthly wash silk fabrics or high-strength bright and beautiful silk fabrics is made, surface is coated with unglazed adhesive film; Block photopolymer substrate and block light cloth and overlapped by velcro; Velcro is fixed on and blocks photopolymer substrate and block on light cloth.
The invention has the beneficial effects as follows: owing to have employed lightweight, soft blocking light cloth, the whole dynamic response blocking tabula rasa is reduced greatly, reduces the requirement of strength of blocking photopolymer substrate, improve strength reliability.Block the textile material that light cloth adopts antiradar reflectivity, drastically increase the performance of eliminate stray light, remote sensor signal to noise ratio (S/N ratio) is got a promotion.Simultaneously because textile material is lighter than carbon fibre composite of the same area, effectively reduce whole quality of blocking tabula rasa.What the present invention can be used for large-scale optical instrument blocks the structure such as tabula rasa, outer light shield.
