Abstract

The invention discloses a device for demonstrating Cheshire cat visual illusion, which consists of an experiment table, a plane mirror, an observation model, a background board, a guide rail, a slide block and a switch for controlling the motion of the slide block. The plane mirror, the background board and the switch are fixed on the experiment table, and the plane mirror can adjust an angle by afixed shaft; the observation model can be fixed at any position of the experiment table through a sucking disc; the guide rail is fixed on the background board; the slide block is clamped on the guid e rail and can move along the guide rail; the switch controls the starting and stopping of the slide block; the ground color of the background board is white; and the heights of the plane mirror, the observation model and the slide block are roughly on the same horizontal line. When the device is used, an observer sits in front of the experiment table, just can see the reflection of the backgroundboard by the right eye, and can see a little dog model of the observation model in front of 60 centimeters or so by the left eye; then the switch is switched on, the slide block moves anticlockwise o n the background board along the circular guide rail; and later, the little dog model disappears in the eyes of the observer.

Description

Cheshire cat optical illusion apparatus for demonstrating and demenstration method

One, technical field

The present invention relates to a kind of apparatus for demonstrating and demenstration method that is used to demonstrate effect optical visual, belong to the experimental demonstration device technical field.

Two, background technology

Britain visual science man Ai Ersaikeer (Al Seckel) demenstration method of having reported a kind of " Cheshire cat optical illusion " optical visual phenomena in " The Art Of Optical Illusions " of showing.This method is the left side that is sitting in a white plane.Left hand is caught the bottom of a mirror and is made minute surface towards the right side.Make mirror reflecting surface aim at wall back to your nose.The rotation minute surface makes your right eye can just see the reflection of wall, and left eye is seen the face that is sitting in 60 centimetres of your friends of the left and right sides in the place ahead simultaneously.The right hand is held blackboard eraser and is moved counterclockwise before white plane.Friend's face has disappeared in your eye.Above-mentioned result of study is done lecture experiment for students in middle and primary schools, the children of kindergarten, and it is very useful perhaps doing scientific popularization work in popular science propaganda department.But said method the time need be prepared a lot of stage properties in demonstration, and The above results is the artificial result who observes on the one hand, and its can be because of the difference of the intensity of observer's sight, hold the blackboard eraser motion and take the poor stability of level crossing, is difficult for observing the result.On the other hand, only depend on human to hold blackboard eraser motion and take level crossing, can cause the tired out of people's arm.Up to the present, also there are not a kind of Special Equipment that is used to observe and method.

Three, summary of the invention

For overcoming the deficiencies in the prior art, the invention provides a kind of reasonable in design, easy to manufacture, easy to use, can effectively carry out Cheshire cat optical illusion optical visual phenomena apparatus for demonstrating and demenstration method.

Cheshire cat optical illusion optical visual phenomena apparatus for demonstrating, by laboratory table, level crossing, observation model, background board, guide rail, slide block and the switch that is used to control slide block movement form, level crossing, background board and switch are fixed on the laboratory table, and level crossing can be with the stationary shaft adjusting angle; Observe model can be fixed on laboratory table by sucker optional position; Guide rail is fixed on the background board; Slide block is stuck on the guide rail, can be along guide rail movement; Switch is controlled the startup of slide block and is stopped; The background color of background board is a white; The height of level crossing, observation model and slide block is roughly on a horizontal line.

Described laboratory table is a right angle table.

Described observation model is " doggie " model, is made of " doggie " model, support and sucker.

Described guide rail is a kind of guide rail of circular closure.

Described slide block is with electrically driven (operated), and behind the unlatching switch, slide block can be done counterclockwise circular motion along circular guideway.

Cheshire cat optical illusion optical visual phenomena demenstration method, its concrete demenstration method is:

(1) before the observer is sitting in laboratory table, place in place observing model, regulate level crossing, make right eye can just see the reflection of background board, left eye is seen about 60 centimetres " doggie " models of observing model in the place ahead simultaneously.

(2) open switch, slide block moves on background board counterclockwise along circular guideway, and after a while, " doggie " model has disappeared in observer's eye.

The present invention promptly can be used as experimental demonstration device and the method that effect optical visual is observed, also can be used as a kind of game device and method, make people particularly the teenager in the process of recreation, when strengthening game-play enjoyment, deepened perceptual knowledge to effect optical visual.
