Abstract
The utility model relates to a light transmission and image transmission beam splitter for light radiation measuring and aiming, belonging to an optical device in the system of light radiation measuring and aiming, which comprises a light transmission beam8 and an image transmission beam9 for light radiation measuring and aiming. One end of the light transmission beam8 is enwrapped in the central position of the image transmission beam9, the other end is discrete with the image transmission beam9. The optical surface diameter ratios of the light transmission beam8 and the image transmission beam9 are 1:5-1:10. The fiber used by the light transmission beam8 and the image transmission beam9 can be one of the following materials: 1) quartz fiber; 2) multi-component glass optical fiber; 3) polymer optical fiber. Since the beam splitter is made of a flexible optical fiber, the beam splitter can be bended and convoluted arbitrarily without affecting the properties of light transmission and transmission. The utility model has the advantages of greatly saving the room, facilitating installation and use, in particular to observing the objective which the user cannot or is not convenient to approach, due to lengthening the light transmission beam8 and the image transmission beam9 of the beam splitter.
Description
Technical field:
The invention belongs to the optical device that relates in optical radiation measurement and the sighting system.
Background technology:
Spot meter, some spectroradiometer, and all carry out the instrument of optical radiation measurement to run-home all need and measure and light path design that aiming is carried out simultaneously.At present, being considered to superior technical scheme is the Prichard system.It can accomplish 100% aiming, and keeps the spectrum formation (do not have and select to absorb) of target light signal and eliminate polarization in measuring light path.Its light channel structure and principle of work are as shown in Figure 1.Tested zone is imaged on the measuring light hurdle 2 by object lens 1, and this light hurdle 2 comprises a reflector, and a hole 3 is arranged on it.Pass the light of hole 3, incide on the detector 4, meanwhile, reflexed to the eyepiece 6 of instrument via mirror 5, thereby tested zone and surrounding environment just can be seen simultaneously by the light of the remainder on hole 3 and light hurdle 2 reflection.The former becomes a blackspot and appears at above the latter.Because this system is " firmly " light channel structure, it need occupy bigger space in instrument.For this reason, the instrument that this type of light path system is housed usually seems, and volume is big, Heavy Weight.Carry, operate all very inconvenient, also be not suitable for not allowing operating personnel to use, as high temperature, have scene of nuclear radiation danger or the like near the special on-the-spot of instrumentation at some.
Summary of the invention:
The objective of the invention is to: propose a kind of light transmission and image transmission beam splitter that is used for optical radiation measurement and aiming, replace two catoptrons in the Prichard system, to form " soft " light path system of saving the space.
Technical solution of the present invention is: it comprises that the biography light beam 8 and the biography that are used for optical radiation measurement and aiming resemble bundle 9, passes light beam 8 one ends and is wrapped in the center that biography resembles bundle 9, and it is discrete that the other end and biography resemble bundle 9.Passing light beam 8 and passing the diameter ratio that resembles bundle 9 logical light faces is 1: 5-1: 10.It can be one of following material that biography light beam 8 and biography resemble bundle 9 used fibers: 1) quartz fibre; 2) multicomponent glass optical fiber; 3) polymer optical fiber.According to the Prichard system, biography light beam 8 is wrapped in and passes the A end that resembles in the bundle 9 in this beam splitter, is positioned on the imaging surface of object lens 1.Biography resembles bundle 9 terminal B eye lens 6 or CCD monitors, can observe the image of measured target by it.Its terminal C and detector 4 that passes light beam 8 joins.This shows that this " soft " light path system can replace Prichard " firmly " light path system fully.Because it is this beam splitter is to be made by flexible optical fibre, curved between can being appointed by do not influence the biography optical transmission performance with spiraling.It is not only saved institute greatly and takes up space, and is convenient to the installation and the use of instrument, especially by passing light beam 8 in the lengthening beam splitter or passing the length that resembles bundle 9, can allow the user away from can not or the approaching target of inconvenience observe.
Description of drawings:
Fig. 1 is a Prichard system light path synoptic diagram;
Fig. 2 is the utility model light path synoptic diagram.
Embodiment:
2w=3 ° of nitometer field angle, silica fibre passes beam diameter φ=0.2, polycomponent optical fiber facsimile beam φ=1.8, beam splitter length is 1m.The A end of beam splitter is positioned on the imaging surface of object lens, and the B end joins with eyepiece 6, and the C termination has the silicon photocell of optical filter.
