Abstract
The utility model relates to a light path demonstrating device for measuring infinitesimal displacement through an optical lever method. Operating steps of a test carried out by original experimental equipment can not be grasped by students easily, the visuality is poor, and the demonstrating effect is not good. The light path demonstrating device for measuring infinitesimal displacement through the optical lever method comprises a laser generator (2), wherein the laser generator is corresponding provided with a scaleover ruler (1) with a small hole; a plane mirror (2) is put on a corresponding position of laser penetrating through the hole, and is arranged on a support; the laser is irradiated on a camera (5) in the direction of a telescope (4) through a light path reflected by the plane mirror; and the camera is provided with a connecting circuit for transmitting an electric signal to a display (6). The light path demonstrating device is applied in physical experiments.
Description
Technical field
the utility model relates to the experimental apparatus that a kind of Physical Experiment is measured.
Background technology
are current; It is simple because of its apparatus structure that the optical lever method is measured the micro-displacement experimental provision, and can improve measuring accuracy, is the required experiment of Physical Experiment in the colleges and universities; Existing experimental facilities comprises: telescope and rule, the level crossing of adjustable angle.
experimentation is such: through the adjustment to instrument, make the light of ruler reflection after flat mirror reflects, get into telescope, the student can see the numerical value of rule picture in telescope, and the variation of record numerical value.
The operation steps student that makes an experiment is not easy to grasp
original experimental facilities.Especially the classmate who has operates for the first time, and experimental principle understanding is not enough, has half knowledge when causing operating, and grasps the marrow of experiment, causes the student in the instrument adjustment process, and the picture of from telescope, observing rule is relatively more difficult, and teaching efficiency is relatively poor.
Summary of the invention
the utility model provides a kind of visuality that strengthens the optical lever light ray propagation, strengthens the light path apparatus for demonstrating of the optical lever method measurement micro-displacement of students'understanding.
The purpose of the invention is achieved in that
optical lever method is measured the light path apparatus for demonstrating of micro-displacement; Its composition comprises: laser generator; Described laser generator correspondence is equipped with the scaleover chi that has aperture, passes on the correspondence position of laser of aperture and lays level crossing, and described level crossing is contained on the support; Laser impinges upon on the camera of telescope direction through the light path of flat mirror reflects, and camera has electric signal is transmitted the into CC of display.
described optical lever method is measured the light path apparatus for demonstrating of micro-displacement, before described laser generator is triggering, sprays with spraying plant, the space carrier that LASER Light Source is had under visual condition, reflect.
[0008] beneficial effect:
1. this product strengthened the optical lever light ray propagation visuality, strengthen students'understanding, the utility model improves original instrument, increases LASER Light Source, spraying plant, and the light ray propagation path is come into plain view.
the utility model solves the technical scheme that its technical matters adopted: near the telescopical scale zero graduation of model of epistolary art line, make a call to an aperture; LASER Light Source is sent by aperture; The place passes to display by camera with image at telescope ocular, and the student can directly be observed the effect of image by display.For the ease of observing the light ray propagation path, to spray between level crossing and model of epistolary art telescope with sprayer, light is owing to the scattering of little water droplet, and the direction of propagation can be known to be seen, has reached the purpose of demonstration.
The beneficial effect of
the utility model is, can in teaching process, make light ray propagation path visual and clear more, and the student comes into plain view for the experimental principle of the little displacement of optical lever method micrometer, and instrument is simple.
Description of drawings:
accompanying drawing 1 is the use synoptic diagram of this product.
Embodiment:
Embodiment 1:
a kind of optical lever method is measured the light path apparatus for demonstrating of micro-displacement; Its composition comprises: laser generator; Described laser generator correspondence is equipped with the scaleover chi that has aperture, passes on the correspondence position of laser of aperture and lays level crossing, and described level crossing is contained on the support; Laser impinges upon on the camera of telescope direction through the light path of flat mirror reflects, and camera has electric signal is transmitted the into CC of display.
described laser generator 2 see through aperture on the rule 1 with Laser emission to the level crossing 3 that is placed on the support; Laser is through level crossing 3 reflections; Be injected into telescope 4 directions and impinge upon on the camera 5, and electric signal is transmitted into display 6 by camera 5.
Embodiment 2:
above-mentioned optical lever method is measured the light path apparatus for demonstrating of micro-displacement, before triggering laser generator, sprays with spraying plant 7, and LASER Light Source is reflected under visual condition.Like this, the laser of launching can carry out scattering under the water droplet refraction action, makes the operator be clear that the incident and the reflection paths of laser, has strengthened the ornamental of testing.
