Abstract
The invention discloses a multi-spectrum polarizing light filter wheel. The light filter wheel is of a disc type structure and comprises a shaft sleeve, a heat-insulated inner ring and a metallic outer ring, wherein the shaft sleeve and the metallic outer ring are made from aluminum LY-12, the heat-insulated inner ring is made from a nonmetallic material, i.e., fiberglass-reinforced plastics, and 16 light through holes are uniformly distributed in the metallic outer ring. The light filter wheel has the advantages that the light filter wheel has relatively high dimensional precision and temperature control precision; the light filter wheel has a special groove design which is beneficial to the mounting of a polaroid and a light filter; by a lightweight design, the rotary inertia of the light filter wheel is reduced.
Description
Technical field
The present invention relates to the precision optics component of machine technology of space remote sensing instrument, specifically refer to a kind of for light splitting
The filter wheel of spectrum, point polarization.
Background technology
It is one of key technology of some optical remote sensing detection instruments to carry out spectrum and polarization parsing using filter wheel mechanism.
External partial spectrum also uses this design with polarization remote sensing instrument, and the designed reliability is good, simple for structure.But limit
In technology blockage, the specific design details of external filter wheel mechanism is difficult to obtain, it is necessary to be independently designed, realize spectrum resolution
The function of being parsed with polarization, and meet the requirements such as temperature environment is stable, installation accuracy is high, load inertia is small.
The content of the invention
The present invention is spectral, point polarization problem that optical remote sensing instrument is solved using optical filtering wheel mode, realizes that instrument is more
The detecting function of spectrum, many polarizations.
A kind of multispectral polarizing filter wheel, is made up of axle sleeve 1, heat-insulated inner ring 2, metal outer ring 3, it is characterised in that：
Together with described axle sleeve 1 passes through screw-type structures join with heat-insulated inner ring 2, heat-insulated inner ring 2 and metal outer ring 3 are logical
Cross screw-type structures join together；16 are uniformly distributed on filter wheel metal outer ring 3 can install the logical of optical filter and polarizer
Unthreaded hole, into " Ω " shape, its straight flange is used for the installation positioning of polarizer or optical filter to light hole circumference.
The material of described heat-insulated inner ring 2 is fiberglass, and there are 8 lightening grooves centre.
The advantage of the filter wheel is：
With dimensional accuracy and temperature control precision higher.Designed with special groove, be conducive to polarizer and optical filtering
The installation of piece.
Brief description of the drawings
Fig. 1 is filter wheel structure chart.
Fig. 2 is filter wheel cutting structure chart.
Including 1- axle sleeves, the heat-insulated inner rings of 2-, 3- metals outer ring.
Specific embodiment
The present invention includes axle sleeve 1, heat-insulated inner ring 2, metal outer ring 3.16 round light holes are set on metal outer ring 3,
Even to be distributed on metal outer ring 3, two circular holes are that 22.5 ° of ± 5 ＂ are mainly used to place optical filter, polarizer with respect to the angle at center
Deng optical mirror slip.Axle sleeve 1 and metal outer ring select the aluminium of LY-12, heat-insulated inner ring to select fiberglass.In the outer rim of metal outer ring 3
16 breach (such as Fig. 1) are set, inertia force during mitigating its weight and rotation.Heat-insulated inner ring is molded in outside axle sleeve 1 and metal
Between circle 3, a firm entirety is made.Heat-insulated inner peripheral surface opens symmetrical lightening grooves, mitigates the weight of filter wheel.
Claims (2)
1. a kind of multispectral polarizing filter wheel, is made up of axle sleeve (1), heat-insulated inner ring (2), metal outer ring (3), it is characterised in that：
Described axle sleeve (1) and heat-insulated inner ring (2) by screw-type structures join together, heat-insulated inner ring (2) and metal outer ring
(3) by screw-type structures join together；16 are uniformly distributed on filter wheel metal outer ring (3) can install optical filter with polarization
The light hole of piece, into " Ω " shape, its straight flange is used for the installation positioning of polarizer or optical filter to light hole circumference.
