Abstract
The utility model discloses a pin-hole imaging demonstration instrument which is mainly composed of an inner cylinder, an outer cylinder, a translucent screen and an aperture. The demonstration instrument is characterized in that one end of the inner cylinder is provided with the translucent screen and the other end is provided with a first baffle plate; an observation hole is arranged on the first baffle plate; a calibrated scale is arranged on the outer side wall of the inner cylinder; one end of the outer cylinder is provided with a second baffle plate; a light hole and a rotating shaft are arranged on the second baffle plate; the aperture is arranged on the second baffle plate through the rotating shaft; circular, triangular and quadrangular small holes arranged in a circle are arranged on the aperture; and the inner cylinder end provided with the translucent screen is sleeved inside the outer cylinder. The demonstration instrument with a simple structure facilitates experiment operations and achieves obvious, stable and accurate phenomena. A user can directly observe, read the scale, record data and acquire a conclusion. Students are further enabled to understand and master the light linear propagation principle in a convenient way.
Description
Technical field
The utility model relates to a kind of teaching aid, is a kind of for demonstrating the demonstrator of pinhole imaging system specifically.
Background technology
In teaching, optics is the not wield part of student, teacher is in the process of explanation, phenomenon and the feature that is difficult to image explanation pinhole imaging system, traditional lecture experiment visibility is little, and student cannot operate and observe the feature of pinhole imaging system in person, is not easy to the distance relation of minute exploring and thing, especially the student who there is no experience of life, can only memorize mechanically textbook conclusion.
Summary of the invention
The purpose of this utility model is the pinhole imaging system demonstrator that a kind of student's of being convenient to operational observations is provided, also can improves student's interest.
To achieve these goals, the utility model is mainly by inner core, urceolus, translucent screen and aperture form, one end of described inner core is provided with translucent screen, the other end is provided with baffle plate I, in described baffle plate I, be provided with observation port, on the outer side tube-wall of described inner core, be provided with rule, described urceolus one end is provided with baffle plate II, in described baffle plate II, be provided with light hole and rotating shaft, described aperture is arranged in baffle plate II by rotating shaft, and it is circular that a circle is set on aperture, triangle, tetragonal aperture, one end that described inner core is provided with translucent screen is enclosed within urceolus.
By above setting, the beneficial effects of the utility model: not only simple in structure, be convenient to experimental implementation, and phenomenon is obvious, stable, accurate, directly observation, reading, record data, reach a conclusion, make student be convenient to understand and grasp the rule of linear propagation of light.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, inner core, 2, urceolus, 3, translucent screen, 4, aperture, 5, baffle plate I, 6, observation port, 7, rule, 8, baffle plate II, 9, light hole, 10, rotating shaft.
Embodiment
As shown in Figure 1, the utility model is mainly comprised of inner core 1, urceolus 2, translucent screen 3 and aperture 4, one end of inner core 1 is provided with translucent screen 3, the other end is provided with baffle plate I 5, in baffle plate I 5, be provided with observation port 6, on the outer side tube-wall of inner core 1, be provided with rule 7, urceolus 2 one end are provided with baffle plate II 8, in baffle plate II 8, be provided with light hole 9 and rotating shaft 10, aperture 4 is arranged in baffle plate II 8 by rotating shaft 10, and a circle circle, triangle, tetragonal aperture are set on aperture 4, one end that inner core 1 is provided with translucent screen 3 is enclosed within urceolus 2.
By above setting, inner core 1 can be in the interior slip of urceolus 2, and the number of degrees that translucent screen 3 can deduct by the length of urceolus 2 rule 7 to the distance of aperture 4 draw; Aperture 4 can 10 rotate around the shaft, is convenient to observe the image that difform aperture produces.
The feature that adopts the utility model to probe into pinhole imaging system, student sees rear very clear, and abstract physical principle is resided among simple experiment, has improved student's interest, reached the effect of getting twice the result with half the effort, thereby made student recognize intuitively the rectilinear propagation rule of light.
