Abstract

The utility model discloses an identifiable reticle. The center of the reticle is provided with an imaging identification. The imaging identification is round, square, cross, I-shaped or Y-shaped. The identifiable reticle is arranged in front of the light source. The image through the reticle is provided with the imaging identification on the reticle. The imaging identification which is round, square, cross, I-shaped or Y-shaped is easily separated form the real imaging area sent from the light source. The identifiable reticle is suitable for not only one imaging but also two or more imaging. The identifiable reticle has the advantages of simple structure, wide scope of application, easy operation and exact imaging, which is suitable for multi-target imaging and easily identifies the imaging position.

Description

But identification graticule

Technical field

The utility model belongs to optical precision test and measuring field, relates to a kind of optical precision test and measuring device, but especially a kind of identification graticule.

Background technology

Graticule or target identification plate are a kind of important accessories in the optical instrument, its basic function be to target position and be convenient to observation etc.In many optical instruments, graticule all plays an important role.In the prior art, graticule can be divided into substantially to be had scale and not to have two kinds of scales, many with the graticule that does not have scale on the digital technology at present.

Present high-accuracy optical surveying instrument such as autocollimator or parallel light tube etc., major part all is to carry out target identification with forms such as cruciform, in-line or M shapes, but so just having a problem produces: when target is under the multiobject situation because target is not one, be easy to cross-coincidence between the target (or target picture), real goal not easy to identify.Position by continuous adjustment picture also can reach the purpose of differentiating picture, but wastes time and energy, and especially when as too big, when can't show fully, just is difficult to identification more.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of graticule of being convenient to computing technique or operating personnel's identification is provided.The technical solution adopted in the utility model is:

But a kind of identification graticule, middle position is provided with the imaging sign on the described graticule.Described imaging sign is circular, square, cruciform, I-shaped or fork-shaped.

But should be convenient to digital technology or operating personnel's resolution by the identification graticule; Its principle of work is: but should place light source the place ahead by the identification graticule, having imaging sign on the graticule through the imaging meeting behind the graticule, is that circular, square, cruciform, the I-shaped or just easy true imaging that light source is sent of fork-shaped distinguish according to the imaging sign; But this identification graticule both had been suitable for an imaging, was more suitable for the situation in two or more imagings.

The utility model has the advantages that simple, applied widely, the easy operation of apparatus structure, accurate, the suitable multi-target imaging of imaging, easy identification image space.

Description of drawings

Fig. 1 is former beginning and end sign image;

Fig. 2 is the original image that identified;

Fig. 3 is that the image after the utility model is regulated is adopted in former beginning and end sign imaging;

Fig. 4 is the original image that has identified after the utility model adjusting is adopted in imaging.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Fig. 1 and Fig. 2 two pictures for not become before and after regulating through the cross-graduation plate that identifies, wherein Fig. 2 is the image that Fig. 1 is become after overregulating.As shown in the figure, under these circumstances, have four cross pictures among the figure, and the cross that we need looks like to have only two, need examine and to differentiate real picture.And work as cross more for a long time, looking for picture will be a very huge job.

Fig. 3 and Fig. 4 break the cross-graduation plate of " X " sign and are regulating two pictures that front and back are become for the center, wherein Fig. 4 is the image that Fig. 3 is become after overregulating.As shown in the figure, in this case, which cross we can tell at a glance is the picture that we need, and has improved greatly for the efficient of looking for picture.

Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by claims of being submitted to.

Claims

1. but identification graticule is characterized in that: middle position is provided with the imaging sign on the described graticule.

2. but identification graticule according to claim 1 is characterized in that: described imaging sign is circular, square, cruciform, I-shaped or fork-shaped.
