Abstract
The utility model relates to a demonstrator for simulating eye imaging. The demonstrator comprises a pressure variable lens, a smog chamber connected with the pressure variable lens, and sheet glass which is arranged on the smog chamber and opposite to the edge of the pressure variable lens. According to the demonstrator, the pressure variable lens is used for simulating a crystalline lens of a human eye, and the sheet glass is used for simulating a retina of the human eye, wherein the pressure variable lens can change into a convex lens or a concave lens in different thicknesses under the action of hydraulic pressure, and the focal length of the lens is changed, so that a human eye imaging demonstrator can be formed. Therefore, problems in teaching are solved and an ideal teaching effect can be achieved.
Description
Technical field
The utility model relates to a kind of apparatus for demonstrating of simulating eye imaging.
Background technology
In the conventional physical teaching; In the process of adjusting, myopia, farsightedness and the correction thereof of lecturing the image-forming principle of eyes, normal eye; Usually rely on wall chart and textbook diagram and explain, owing to the student does not know the structure and the image-forming principle of eyeball, so; This kind mode of giving lessons is difficult to inspire students'interest in learning, and its teaching efficiency is not ideal.
In order to find the point of penetration of learning aid; Making teaching be full of strong experiment atmosphere, making in the teaching process can be vividly, image, motivate students' interest in learning, in the prior art a kind of model that can simulate eyes of employing usually; This model is by one group of convex lens and source of parallel light that focal length is different; And the bottle formation that milk and water mixed solution are housed, wherein, the convex lens in the model are equivalent to eye's lens; The rear wall of bottle is equivalent to the retina of eyes, and milk and water mixed solution are equivalent to the vitreum of eyes.With the way of the image-forming principle of the model demonstration eyes of this kind structure and vision correction the time, be the myopia model, can adopt concavees lens to correct, when being the farsightedness model, can adopt convex lens to correct.Though this kind model can be demonstrated out the image-forming principle of eyes intuitively; But because the employing of the crystalline lens in the model is the convex lens of solid shape; And the focal length of this kind convex lens is changeless, so, utilize this model when explanation " convex lens are to the converging action of light and the concavees lens disperse function to light "; The student can not see actual light path, lets the student be difficult to realize to convex lens to the converging action of light and the concavees lens principle to the disperse function of light; Simultaneously, explanation " same material, the identical lens of size during the thickness relationship of focal length and lens, must adopt at least three different glass lenss of thickness to give student experimenting, make student's indigestion focal length and form images between relation; In addition; When explanation contents such as " myopia and presbyopic formation and rectifications "; The student can not see the relation of the change eyesight of lens thickness intuitively, can only can recognize just that with thinking deeply independently eye lens is a kind of lens that can focus through explanation.
Summary of the invention
The purpose of the utility model provides a kind of utilization can see the change of lens thickness and the apparatus for demonstrating that the mode of relation between the imaging solves the simulation eye imaging of the existing problem of teaching intuitively.
The apparatus for demonstrating of the simulation eye imaging that the utility model proposed comprises presses variant lens and the smog chamber that links to each other with this pressures variant lens transparent mode, and be arranged in this smog chamber and with pressure variant lens relative edge edge on glass sheet.
Said pressure variant lens have a cylindrical housings, away from the side of housing the flexible transparent sheet are installed in this cylindrical housings, are provided with the liquid filling orifice at the top of this cylindrical housings.The below of said smog chamber is provided with the smog filling orifice.
The pressure variant lens that the apparatus for demonstrating of the simulation eye imaging that the utility model proposed adopts come anthropomorphic dummy's eye's lens; The glass sheet that adopts is simulated the retina of human eye; Pressure variant lens wherein can develop into the convex lens or the concavees lens of different-thickness under the effect of fluid pressure, the variation of the focal length of lens can form " eyes imaging demonstrator "; Thereby solve the problem that exists in the teaching, can obtain very desirable teaching efficiency; Simultaneously, the smog that injects in the smog chamber can make the student clearly see light path, promptly sees the principle of the converging light in the smog chamber.
Description of drawings
Accompanying drawing 1 is the surface structure synoptic diagram of an embodiment of apparatus for demonstrating of the simulation eye imaging that proposes of the utility model;
Accompanying drawing 2 is side views of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the overall appearance structure of an embodiment of apparatus for demonstrating of the simulation eye imaging that the utility model proposes.This apparatus for demonstrating comprises presses variant lens 1 and smog chamber 2, and anthropomorphic dummy's eyes retina glass sheet 23.Wherein, press variant lens 1 to have a cylindrical housings 11, be provided with fluid ostium 12 at the top of cylindrical housings 11, a side of cylindrical housings 11 is equipped with flexible transparent sheet 13; Smog chamber 2 has a section and is similar to oval-shaped housing 21; Be equipped with in a side of housing 21 to be used for fixing and press variant lens 1 limit base 22; Be equipped with on the housing 21 and on the face relative with limit base 22 can anthropomorphic dummy's eyes retina glass sheet 23, support member 24 and smog filling orifice 25 are installed below housing 21.
When utilizing the principle of this apparatus for demonstrating simulation eye imaging; At first light source is placed on the place ahead of pressing variant lens 1; In pressing variant lens 1, inject water through fluid ostium 12 then and adjust its focal length, when object forms the real image that handstand clearly dwindles on glass sheet 23, move light source along far and near direction again with pressure variant lens 1; On glass sheet 23 during image blur; Focusing makes real image clear again, and image-forming principle and regulating action with the explanation eyes show that simultaneously eye lens is the convex lens that can focus.Utilize aforesaid way can also explain the camera principle, and the simulation myopia and the presbyopic origin cause of formation.
Claims (3)
