Abstract
The utility model discloses a kind of laser aid producing dummy keyboard pattern; comprise mirror holder, LASER Light Source, lens, pattern type diffraction optical element and protective lens; described LASER Light Source and described lens are set in turn in described mirror holder; described protective lens is arranged at one end of described mirror holder; be positioned at the side of described lens, the inner side of described protective glass is provided with described pattern type diffraction optical element.The utility model produces virtual keyboard image by pattern type diffraction optical element at arbitrary plane, again by the finger position of infrared laser and cmos sensor perception user, user can use laser virtual keyboard as use standard machinery keyboard or touch-screen, meets the advantage of ergonomics.
Description
Technical field
The utility model relates to a kind of laser aid, particularly relates to a kind of laser aid producing dummy keyboard pattern.
Background technology
The keyboard that current people use is all that standard machinery keyboard or touch-screen equally use laser virtual keyboard.Laser virtual keyboard is applied to mobile phone and panel computer, can't resolve the shortcoming not meeting ergonomics, has brought inconvenience.
Utility model content
The purpose of this utility model is just to provide a kind of laser aid producing dummy keyboard pattern to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises mirror holder, LASER Light Source, lens, pattern type diffraction optical element and protective lens; described LASER Light Source and described lens are set in turn in described mirror holder; described protective lens is arranged at one end of described mirror holder; be positioned at the side of described lens, the inner side of described protective glass is provided with described pattern type diffraction optical element.
The beneficial effects of the utility model are:
The utility model produces virtual keyboard image by pattern type diffraction optical element at arbitrary plane, again by the finger position of infrared laser and cmos sensor perception user, user can use laser virtual keyboard as use standard machinery keyboard or touch-screen, meets the advantage of ergonomics.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation producing the laser aid of dummy keyboard pattern described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises mirror holder 1, LASER Light Source 2, lens 3, pattern type diffraction optical element 4 and protective lens 5; LASER Light Source 2 and lens 3 are set in turn in mirror holder 1; protective lens 5 is arranged at one end of mirror holder 1; be positioned at the side of lens 3, the inner side of protective glass 5 is provided with pattern type diffraction optical element 4.
Principle of work of the present utility model is as follows:
First according to the wavelength of incident laser, the parameters such as operating distance, design corresponding holographic structure by diffraction optics, then utilize the method for photoetching and etching to be shifted and be produced on quartz substrate on the surface, obtain diffused diffraction optical element.
During work, beam of laser scioptics, through the laser that expands by pattern type diffraction optical element by the pattern projection of dummy keyboard to target area.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model instructionss and accompanying drawing content are done, is all contained within interest field of the present utility model.
