Description
Technical field
The utility model belongs to teaching experiment teaching aid field, is related to a kind of visual persistence effect demonstrating experiment device.
Background technique
For human eye in observing scene, optical signal is passed to cerebral nerve, need to pass through one of short duration time, the effect of light terminates
Afterwards, visual image does not disappear immediately, and this remaining vision claims " after image ", this phenomenon of vision is then referred to as that " vision is temporary
It stays ".Vision is actually that the lenticular of eyes is leaned on to be imaged, and photosensory cell is photosensitive, and converts optical signal into neuroelectricity, is passed
It returns brain and causes human visual.The photosensitive of photosensory cell is by some photopigments, when the formation of photopigment needs certain
Between, here it is the formation mechenisms of the persistence of vision.
The time of the persistence of vision is about 0.05~0.2s.Our PPT projection at dynamically also with this principle, often
One width picture is static, but when PPT allows light stimulus optic nerve with speed more than 20 width picture per second, and two width pictures substitute
Interval only have about 0.01 second, there have been the dynamic effects of screen picture for this.In daily life, many phenomenons and vision
It persists related.Such as: the fluorescent lamp that we use will extinguish 100 times each second, but since human eye has the spy of the persistence of vision
Property, under normal circumstances, we are detectable flashing for light.
In order to enable human eye significantly to see, film projector just utilizes this principle, when we are put with 24 lattice
When reflecting, it is seen that not only obscure, but also have the image of flashing." one fuzzy " is not that your eyes are seen, as visual signal
Receiver, eyes are that each timing node has a clearly picture, and if only your brain has little time processing, you will
Feel blur at the moment, or says it is to fall frame.Therefore 24 lattice are changed to 48 lattice just by special setting on film projector
Reduce fuzziness.
Currently, for relatively common visual persistence phenomenon, it is direct to generally use preaching method in the teaching process in middle school
It imparts knowledge to one's students, or for the example in a little real lifes, but student understands to get up or be relatively abstracted, it is difficult to which this is known
Know point to carry out going deep into understanding, it is also difficult to the learning interest of mobilizing students.

Specific embodiment
Illustrate the embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition
Different specific embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer
With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that institute in following embodiment
The diagram of offer only illustrates the basic conception of the utility model in a schematic way, in the absence of conflict, following embodiment and
Feature in embodiment can be combined with each other.
Fig. 1-Fig. 2 is please referred to, the element numbers in attached drawing respectively indicate: power unit 1, control unit 2, swing bar 3, light
Source 4, driving unit 5, rotation axis 6, display board 7.
The utility model relates to a kind of visual persistence effect demonstrating experiment devices, comprising: swing bar 3 is generated for issuing
The dotted light of visual persistence phenomenon, it is described several including mounting plate and several light sources 4 being arranged on the side of mounting plate
A light source 4 in matrix arrangement on a mounting board；Rotation axis 6, for installing swing bar 3 and driving mounting bar with the rotation axis
6 axle center is axis rotation, is fixedly connected with one end of swing bar 3；Driving unit 5, for driving rotation axis 6 to generate with described turn
The axle center of moving axis 6 is that axis is rotated, and is fixedly connected with the rotation axis 6；And power unit 1, for being that the driving is single
Member 5 provides power, is connected with the driving unit 5.
Preferably, further include for control the angular speed, rotation direction that the driving unit 5 drives rotation axis 6 to rotate with
And independently control the control unit 2 that light source 4 is shinny or extinguishes, described control unit 2 and driving unit 5 and power unit 1
It is connected.The shinny of light source 4 can be independently controlled by control unit 2 or is extinguished, and realized by this kind control to different figures
The presentation of case can be image or letter etc..
In the present embodiment, the light source 4 is LED light；The light source 4 is on the side of swing bar 3 along swing bar 3
Length direction linear array is a column；The driving unit 5 is reciprocating motor；The power unit 1 is power supply.Preferably to open up
