Abstract
The invention discloses a kind of double Imaing projectors comprising: a laser projection, a half-reflecting mirror and an ear canal model；Wherein, the half-reflecting mirror is located on the corresponding position of the laser projection, the laser projection include one it is micro electronmechanical scan mirror, scan light beam so as to project one, the light beam that scans of the laser projection is projeced on an imaging surface through the big picture real image that the half-reflecting mirror transmits；On the position for the reflection that the ear canal model is located at the half-reflecting mirror, front end sets a viewing mouth, and rear end sets an ear-drum part, and the light beam that scans of the laser projection is projeced on the ear-drum part of the ear canal model through the small picture real image that the half-reflecting mirror reflects；In this way, learner can be observed the stereoprojection real image of various ear illnesss on the ear-drum part by viewing mouth, meanwhile, operator can scan light beam by watch that big picture real image manipulate the laser projection.
Description
Technical field
The present invention relates to a kind of double Imaing projectors, in particular to a kind of to utilize slur as projection pattern, and teaching is used
Image be projeced on three-dimensional ear canal model, enable learner that can observe easily and study ear by the projection on the ear canal model
Piece various illnesss.
Background technique
Projector released for many years, because its only need one for projection device can video display or display computer
In display content the conference content being stored in laptop is amplified by projector aobvious for example, in convention
Show and watched to more people, or when teaching, the teaching projection piece being stored in laptop is shown by projector, to carry out
Teaching.
But general existing ear teaching is projected as the image of teaching being projeced on the imaging surface of plane,
The various illnesss of learner's observation with study ear are enabled using the image of plane.But the external auditory canal of human body and internal auditory meatus are
Three-dimensional shape, rather than be plane, it is vertical that existing plane formula teaching projection is not easy the reality for making learner understand the various illnesss of ear
Body situation, causes teaching efficiency to be had a greatly reduced quality greatly.
Summary of the invention
In view of this, inventor is according to the manufacturing development and design experiences for being engaged in Related product for many years, for above-mentioned
Target, in detail design with after scrupulous assessment, eventually a true tool practicability the present invention.
The main purpose of the present invention is to provide a kind of double Imaing projectors, are used using slur as projection pattern will impart knowledge to students
Image be projeced on three-dimensional ear canal model, enable learner that can observe easily and study ear by the projection on the ear canal model
The practical three-dimensional situation of piece various illnesss.
In order to achieve the above object, double Imaing projectors provided by the invention include: a laser projection, a half reflection
Mirror and an ear canal model；Wherein, the laser projection be set to a head model in, it includes one it is micro electronmechanical scan mirror, so as to
Projection one scans light beam comprising various ear illness images；The half-reflecting mirror is set in the head model, is located at the laser and is thrown
On the corresponding position of shadow machine, the light beam that scans of the laser projection is projeced into through the big picture real image that the half-reflecting mirror transmits
On one imaging surface；The ear canal model is set in the head model, and on the position of the reflection of the half-reflecting mirror, front end is equipped with
One viewing mouth, rear end is equipped with an ear-drum part, the small picture real image for scanning light beam and reflecting through the half-reflecting mirror of the laser projection
It is projeced on the ear-drum part of the ear canal model；Whereby, in use, learner can be observed various ears on the ear-drum part by viewing mouth
The stereoprojection real image of piece illness, meanwhile, operator can scan light beam by watch that big picture real image manipulate the laser projection；
In this way, learner can observe easily the practical three-dimensional external form with the study various illnesss of ear by the projection on the ear canal model
And situation, achieve the purpose that greatly improve learning effect.
In one embodiment of this invention, which is the half-reflecting mirror that a reflectivity is 30%~70%.
To enable auditor to the purpose of this creation, shape, constructing apparatus feature and its effect, further understanding is done
With understanding, hereby cooperate schema for embodiment, detailed description are as follows:
Detailed description of the invention
Fig. 1 is the floor map of double Imaing projectors provided by the invention.
Description of symbols: 10- laser projection；11- imaging surface；20- half-reflecting mirror；30- ear canal model；31- viewing
Mouthful；32- ear-drum part；40- head model.
Specific embodiment
The present invention provides a kind of " double Imaing projectors ", as shown in Figure 1, double Imaing projectors provided by the invention
It include: a laser projection 10, a half-reflecting mirror 20 and an ear canal model 30.
Wherein, the laser projection 10 be set to a head model 40 in, it includes one it is micro electronmechanical scan mirror (not shown),
Light beam is scanned comprising various ear illness images so as to project one.
The half-reflecting mirror 20 is set in the head model 40, should on the corresponding position of the laser projection 10
The light beam that scans of laser projection 10 is projeced on an imaging surface 11 through the big picture real image that the half-reflecting mirror 20 transmits.
The ear canal model 30 is set in the head model 40, on the position of the reflection of the half-reflecting mirror 20, front end
Equipped with a viewing mouth 31, rear end is equipped with an ear-drum part 32, and the light beam that scans of the laser projection 10 is reflected through the half-reflecting mirror 20
Small picture real image be projeced on the ear-drum part 32 of the ear canal model 30.
By the composition of above-mentioned component, as shown in Figure 1, in use, learner can observe the ear-drum part by viewing mouth 31
The stereoprojection real image of various ear illnesss on 32, meanwhile, operator can manipulate the laser projection by watching big picture real image
10 scan light beam；In this way, learner can be observed easily and the study various diseases of ear by the projection on the ear canal model 30
The practical three-dimensional external form and situation of disease, achieve the purpose that greatly improve learning effect.
As shown in Figure 1, the half-reflecting mirror that the half-reflecting mirror 20 can be 30%~70% for a reflectivity.
The foregoing is merely the preferred embodiment of this creation, when cannot be limited the scope of implementation of the present invention with this；Therefore
It is all according to simple equivalent changes and modifications made by scope of the invention as claimed and description, should still belong to of the invention
In protection scope.
