Abstract
The invention relates to laser pattern projection device and method. It includes SCM controlled laser, scanning tilting mirror, and many parallel lasers. The method includes the following steps: using visual persistence effect to emit the laser from the parallel lasers to the scanning tilting mirror; projecting on the screen after reflecting; using SCM to control emitted laser bright-dark to form static or animate pattern or character. The invention has the advantages of compact structure, simple technology, high display contrast, realizing outdoor long distance projection by night, projecting out laser scroll with animate character or pattern, widely using in indoor outdoor occasions such as exhibition etc.
Description
Technical field
The present invention relates to a kind of laser pattern projecting device and method with dynamic patterns.
Background technology
At present, mostly the captions device that uses on the market is LED array screen, or uses the light-emitting component of fixed character such as neon bulb.This captions screen volume is bigger, and installation is set up very inconvenient, generally fixedly use.The equipment that also has some utilization bidimensional scanning mirrors to carry out captions, figure projection, but it uses single beam laser, is used for occasions such as laser engraving, laser marking more, and key is to show complicated figure and literal.
Summary of the invention
The purpose of this invention is to provide a kind of laser pattern projecting device and method, show dynamic or static image or literal by laser scanning, to remedy the deficiencies in the prior art with dynamic patterns.
Technical scheme of the present invention comprises by monolithic processor controlled laser instrument, with the scanning mirror in the rotating shaft that drives by the servomotor that has speed control, it is characterized in that it also comprises a shell that has transparency window, have at two ends in the rotating shaft of bearing the scanning mirror that has three reflectings surface at least is installed, laser instrument is to have 5 laser instruments that are arranged in parallel at least on the reflecting surface of being installed in the shell that is transmitted into the scanning mirror in the rotating shaft.
The reflecting surface of described scanning mirror is plane or the laser that makes scanning at the luminous point that becomes on the screen linear arc cylinder on time and scanning distance.The equation of the arc cylinder of reflecting surface can be sine surface.
The projective techniques of laser pattern is the effect that persists of utilizing vision, with a plurality of laser that laser instrument sent that are arranged in parallel, be transmitted on the minute surface of the scanning mirror in the rotating shaft that drives by servomotor, project after the reflection on the plane such as screen, laser instrument is formed the pattern or the literal of static or animation by the bright dark of Single-chip Controlling shoot laser.
The present invention who constructs thus is rational in infrastructure, and volume is little, and technology and method are simple, and is colored abundant, uses easily.It shows the contrast height, and compact conformation is reasonable, and can be in outdoor remote projection at night, generate large area image, colored abundant, according to the pattern difference of being stored, can project and have the dynamic character or the laser vertically hung scroll of image, and be widely used in various indoor and outdoor occasions such as exhibition, news conference.
The invention will be further described below in conjunction with drawings and Examples.

Embodiment
As Fig. 1, the present invention includes laser instrument 6 by single-chip microcomputer 11 controls, with the scanning mirror 2 in the rotating shaft 5 that drives by the servomotor 3 that has speed control, it is characterized in that it also comprises a shell 1 that has transparency window 8, have at two ends in the rotating shaft 5 of bearing 4 scanning mirror 2 that has three reflectings surface 10 at least is installed, laser instrument 6 is to have five laser instruments that are arranged in parallel at least on the reflecting surface of being installed in the shell 1 10 that is transmitted into the scanning mirror 2 in the rotating shaft 5, and the laser projections that makes scanning is to screen 9.
It is linear and realize the arc cylinder of uniform speed scanning on time and scanning distance at the luminous point that becomes on the screen 9 that the reflecting surface 10 of described scanning mirror 2 is the laser that makes scanning.
The equation of the arc cylinder of described reflecting surface 10 can be the bent cylinder of sine.If use the reflecting surface 10 on plane, should carry out the actual time line correction in the control by 11 pairs of laser instrument 6 emergent lights of single-chip microcomputer.
Described laser instrument 6 is under the control of single-chip microcomputer 11, by sending laser under the programmed control that is stored in single-chip microcomputer 11 in advance or closing laser.The laser that the laser instrument 6 of multicolour is sent is radiated on the scanning mirror 2 after reflecting via laser mirror 7 assemblies.
As Fig. 1, the laser instrument 6 of at least five and at least a color, being used for emission has the laser beam of 0 ~ 10 degree scope dispersion angle, and laser beam irradiation is on scanning mirror 2, and the ray cast of mirror 7 reflections that are reflected after scanning mirror 2 rotates becomes the multi-strip scanning line to the screen 9 and the pattern that forms.Laser instrument is subjected to the control of single-chip microcomputer 11, and servomotor 3 is pressed certain speed and rotated, and is subjected to the laser instrument 6 of single-chip microcomputer 11 controls simultaneously or opens or closes, and utilizes human eye to persist effect and makes the laser scanning line of scanning on wall or screen 9 interrupted and form pattern.
Therefore, the projective techniques of laser pattern is the effect that persists of utilizing vision, with a plurality of laser that laser instrument sent that are arranged in parallel, be transmitted on the minute surface of the scanning mirror in the rotating shaft that drives by servomotor, project after the reflection on the plane such as screen, laser instrument is formed the pattern or the literal of static or animation by the bright dark of Single-chip Controlling shoot laser.
Another embodiment of conduct shown in Figure 3 is radiated on the scanning mirror 2 after the laser that described laser instrument 6 is sent reflects through catoptron 7, and projects on the screen 9.The laser instrument 6 that sends multiple color laser is arranged in parallel with catoptron 7, is used for scanning colored pattern.Be that laser instrument 6 can be multiple color, so that scan colored laser pattern.
The present invention is the effect that persists that makes full use of human eye, makes the multi-stripe laser sweep trace form piece image.If generally require to form Chinese character comparatively clearly, 16 laser instruments are preferably arranged, then laser instrument need be more if form pattern or need multiple color.
