Description

Glasses for strengthening stereoscopic visual sense of planar dynamic picture

The utility model belongs to daily life amusement or education experiment articles for use.

The beginning of this century, Germany scientist Pulfrich found: when the neutral colour filter with a transmitance less (being made as R) covers in people's the eyes one, when removing to observe a pendulum of planar swinging simultaneously with another bore hole again, can see that the movement locus of pendulum becomes the sealing loop-drive of one " solid ", and when different eyes are covered, put opposite along the loop-drive travel direction.This phenomenon is known as the Pulfrich effect.Explanation to this effect is: the speed of vision imaging is relevant with the light intensity of incident eyes, and is then fast by force, weak then slow, thereby, in the Pulfrich effect, the imaging of the eyes that covered by optical filter lags behind another bore hole, and the time interval that falls behind can be described as relaxation time τ.For someone, τ=τ (R), promptly τ is only relevant with the transmitance R of optical filter, when the optical filter transmitance 10 ^-1During the left and right sides, the statistics of τ value is 10 ^-3-10 ^-2Between second.The existence in relaxation time makes two the position differences of same motion particle on direction of motion of seeing at synchronization, wears the particle postition that the eyes of optical filter are seen, and on the particle movement direction, lags behind the position that bore hole is seen.Its result, according to the principle of perspective view, in the composite image of binocular vision, synthetic particle postition (virtual positions) is different, far away or near with actual particle postition, decides according to the difference of institute's hoodwink.In like manner, hoodwink is constant when institute, and the particle movement direction is when changing, and the distance of the composite particle position in the composite image also changes.

If binocular interval is L, its line mid point is S apart from the vertical range on particle movement plane, particle movement V＜＜light velocity C, L＜＜the S establishment, can suppose plane, eyes line place and particle movement plane parallel.Establishing the τ value again can just can bear, and determines that positive and negative method is: when the positive dirction of particle movement left, when then hiding right eye τ on the occasion of, τ is a negative value when hiding left eye.Thus, the distance y that can derive the position deviation real motion plane of composite particle after the imaging is:

y＝ (Vτ)/(L-Vτ) S （L＞｜Vτ｜） （1）

The positive negative indication of y departs to far or to closely.

The simple harmonic oscillator x=Asin(2 π ft of Fig. 1 for deriving) according to formula (1)=and 0.5sin(2 π t) (rice) empty movement locus when wearing the optical filter observation.L, S, the τ value is got 0.065 meter respectively, 2 meters and 0.005 second.

Plane dynamic menu stereoscopic vision strengthens that mirror (be called for short down and strengthen mirror) promptly proposes according to Pulfrich effect and principle thereof.At present, the Pulfrich effect is still rarely known by the people, and is not applied in real life.In the modern society, common (black and white, colour) TV extensively enters family, just the waiting in expectation appearance of stereotelevision of people.Strengthening mirror can make people realize that on a certain degree they appreciate the hope of stereoscopic picture plane.

The Pulfrich effect is the comprehensive effect of aspects such as a kind of physiology and physics.Allowing more people understand its essence and obtaining a kind of means of measuring optic nerve signal transmission speed all is highly significant.This shows that it is highly significant that release enhancing mirror is used it in life ﹠ amusement and education experiment.

It is the basic thought that strengthens the mirror design that eyes are covered with neutral colour filter.Reach this purpose and can adopt various ways.If it can be used in real life, study, reply strengthens the mirror design and proposes more requirements.The eyeglasses frame of using in the life at present used to strengthen on the mirror then more limitation.The utility model provides a kind of usefulness many, convenient and practical container type mirror holder for strengthening mirror.

The mirror holder that strengthens mirror has five assemblies, is respectively tie-beam (Jing Liang) between two mirror legs, two removable picture frames of eyeglass and frame.Become a complete mirror holder (Fig. 3) after the assembling.For optical filter hides the needs of different eyes, the mirror leg can carry out in two opposite directions with the connection of picture frame in the mirror holder design.The mirror leg oppositely after, both can reach anti-dazzling screen and be changed to the purpose of opposite side from a side, be same purpose.Also can adopt the mirror leg axially to change 180 ° of still attachable connected modes (be connected (referring to Fig. 4) of mirror leg and picture frame along it.Also a coupling arrangement should be arranged on each picture frame, become the one handle crutch glasses after making the mirror leg and it being connected, purpose strengthens the needs (Fig. 5) that mirror uses in short-term for adapting to.The connected mode of Jing Liang and picture frame can adopt an end to fix or all unfixed mode in two ends, and frame can have damping ground to slide on beam.This design is to use the same pair of needs (Fig. 6) that strengthen mirror for different people.Strengthen in the design of mirror mirror holder, a device can arranged on the picture frame so that it can be hung on (Fig. 7) on the common spectacles frame.Also can have on the Jing Liang and can make whole mirror holder be supported in device on the nose.

More than She Ji advantage is: the people of any eyes health can both use same pair of restriction that strengthens mirror and be not subjected to the eye size and whether wear glasses.Can to select which eye to be covered effect by optical filter easily best owing to the difference of reasons such as binocular vision.Additional another optical filter makes the mirror leg serve as handle, and one pair strengthens mirror and can doublely use simultaneously.Seem attractive and durable owing to the assembling back is similar to common spectacles.

The release of enhancing mirror of mirror holder of being furnished with the above advantage of tool is with the good effect that produces: 1. in the family life, watch TV (no matter black and white, colour TV) that new enjoyment has been arranged.The enhancing mirror not only makes in dynamic menu can see stereoeffect, and the function that weakens television image luminous point clutter vision protection is arranged.2. can provide a kind of converter tools that makes the dynamic menu three-dimensional to spectators during the common film of cinema screening.3. school can make observation of students arrive the Pulfrich effect more easily, makes some key concept that undergoes in teaching such as physiology, physics.

Fig. 2 is certain design drawing that strengthens mirror mirror holder special case.

Fig. 3 is the assembly of this special case and the shape after the combination.

Fig. 4 shows in this special case by regulating the function that the mirror leg realizes that left and right sides eyeglass exchange is used.

Fig. 5 shows that this special case also can strengthen mirror as a handle type.

Fig. 7 shows that this special case can use simultaneously with other glasses.

According to practical experience, optical filter at first should be neutral, and promptly the light to different wave length has close transmissivity, and transmissivity is 0.1.Optical filter depart from neutral more, the transmissivity value is improper, all will not reach expected effect significantly.The actual use is not subjected to age limit when strengthening mirror, between men owing to there are difference on the effect in physiology and experienced difference.According to experience is arranged, it is good that optical filter preferably covers the better relatively eyes of eyesight.When once using for a long time, preferably change the optical filter position.
