Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is directional reflective apparatus structure schematic diagram, and 101 be lens, and 102 be reflective mirror, and the focus of lens 101 is fallen in instead
On the arc three-dimensional face of light microscopic 102, in this way, focusing on its focus by lens 101 when the light directive lens 101 of light source 104
On, and the light of focal point is reflexed to lens 101 by the reflective mirror 102 in focal point, scatters return projector extremely by lens 101
Observer's eyes 103, return projector and incident direction are on the contrary, i.e. backtracking.
Fig. 2 is flashing directional reflective apparatus structure schematic diagram, opposite Fig. 1 directional reflective apparatus structure, reflective mirror 102 and thoroughly
Cavity 201 is set between mirror 101, and occulter 202 is arranged close to reflective mirror 102 in cavity in cavity 201, occulter 202 can be
It is moved in cavity 201, if the incident light of light source 104 is blocked by occulter 202, return projector disappears, in this way with shading
Body is random or cycle movement makes the light intensity of return projector change, and realizes flicker effect.Realize the side that occulter 202 moves
Formula has 3 kinds: (1) being air or vacuum in cavity 201, (such as vehicle driving) occulter 202 occurs in the case where external vibration
Freely falling body vibration；(2) hydraulically full in cavity 201, (such as vehicle driving) occulter 202 occurs in the case where external vibration
Viscous motion；(3) referring to Fig. 3, elastic component 301(such as spring etc. is connected on occulter 202), by occulter 202 and elastic component 301
Form spring oscillator.
In the case of hydraulically full in (2) cavity 201, when occulter is sufficiently small, Brownian movement, such case can be generated
Under it is available never stop flashing return projector.
Under general light intensity, human eye is most quick to 15 ~ 20Hz signal to the approximate bandpass filter of the response of temporal frequency
Sense, there is very strong flickering (flick), and being greater than 75Hz response is 0, and flickering disappears, and the frequency for just arriving to flickering disappearance is called
Critical fusion frequency (CFF) is in low-pass characteristic, and CFF can be reduced under darker environment, at this moment most sensitive to 5Hz signal,
Basic disappear is flashed greater than 25Hz.Accordingly, flicker frequency selects 5 ~ 20Hz, and the corresponding period is 0.04 second ~ 0.2 second.
