Abstract
The utility model relates to a kind of holography and looks squarely display system, system comprises LED light source (1), projection display screen (2), plane mirror (3) and lens combination (4), according to optical path direction, set gradually LED light source (1), projection display screen (2), plane mirror (3) and lens combination (4), the minute surface of described plane mirror (3) is towards projection display screen (2) and lens combination (4), and the optical path direction of the minute surface normal defence line of plane mirror (3) and projection display screen (2) is angled.Lens combination (4) comprises lens and curved reflector.LED light source (1) comprises redness and green LED lamp set.The light source that display system has adopted different colours is looked squarely in the holography that the utility model provides, can show vehicle speed, navigate, turn to, the integrated information such as broadcast, phone, display effect is good, information is comprehensive, experiences intuitively to human pilot.
Description
Technical field
The utility model relates to that a kind of especially display system is looked squarely in holography for the flight supplementary instrument on aircraft, belongs to optical projection and shows field.
Background technology
1948, Denis adds uncle, and to have invented holography be wavefront reconstruction technology, the ultimate principle of holography is: adopt coherent light irradiating object, the diffraction light wave being produced by object and other a branch of coherent reference optical interference, form the interference pattern of distribution, intensity variation, i.e. hologram according to certain rules.The amplitude of the irradiating object recording in this pattern and phase information, while adopting reference light or its conjugation light-wave irradiation hologram, the amplitude of the original and phase information will show.The development of holography is not sailed right before the wind, until laser instrument, adopted further development from the use holographic technique of axle recording technique and spatial filter.
Along with the development of technology, holographic technique is applied in a plurality of fields, and line holographic projections has been brought into play very intuitively effect in display system, the development and application of this technology also very rapidly.At present, look squarely display technique and also rest on the optical element stage, also have the problems such as transparency and reflectance on display device, price is general also comparatively high.Because the restriction of these technology, has caused this technology and has failed to appear at well in our daily life.
Utility model content
In order to overcome the deficiencies in the prior art, resolve the problem of prior art, make up the deficiency of existing existing product in the market.
The utility model provides a kind of holography to look squarely display system, system comprises LED light source, projection display screen, plane mirror and lens combination, according to optical path direction, set gradually LED light source, projection display screen, plane mirror and lens combination, the minute surface of described plane mirror is towards projection display screen and lens combination, and the minute surface normal defence line of plane mirror and the optical path direction of projection display screen angled.
Preferably, said lens group comprises lens and curved reflector.
Preferably, above-mentioned LED light source comprises redness and green LED lamp set.
Preferably, above-mentioned LED light source and projection display screen be arranged in parallel.
Preferably, said system is connected with car speed meter, steering indicating light, navigating instrument, cruise instrument and instrument instrument.
Preferably, said system is also connected with driving radar with car running computer.
The light source that display system has adopted different colours is looked squarely in the holography that the utility model provides, can show vehicle speed, navigate, turn to, the integrated information such as broadcast, phone, display effect is good, information is comprehensive, experiences intuitively to human pilot.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Reference numeral: 1-LED light source; 2-projection display screen; 3-plane mirror; 4-lens combination; 5-windshield.
Embodiment
For the ease of those of ordinary skills, understand and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
As shown in Figure 1, for system of the present utility model, specifically comprise LED light source 1, projection display screen 2, plane mirror 3 and lens combination 4, according to optical path direction, set gradually LED light source 1, projection display screen 2, plane mirror 3 and lens combination 4, the minute surface of described plane mirror 3 is towards projection display screen 2 and lens combination 4, and the minute surface normal defence line of plane mirror 3 and the optical path direction of projection display screen 2 angled.Lens combination 4 comprises lens and curved reflector.Two secondary reflections by plane mirror 3 and lens combination 4, project the information that needs projection on windshield 5, thereby realized, look squarely Projection Display.
LED light source 1 comprises redness and green LED lamp set.By TFT projection display screen, produce picture material, this projected image is apart from observer's the about 2.7m of eyes.As shown in Figure 1, LED light source 1 be arranged in parallel with projection display screen 2.
System is connected with car speed meter, steering indicating light, navigating instrument, cruise instrument and instrument instrument.Also be connected with driving radar with car running computer.
By with the coordinating of running computer, GPS navigation instrument and driving radar, the utility model can show as
Lower various information:
Velograph;
Steering indicating light;
Navigation direction, the distance of turning from the next one and the street name of next outlet or turning, can realize 3D and show;
Cruise and cruise speed are controlled, if having automatic vehicle apart from cruising control, also can show the distance with front truck;
Meter check or engine failure show;
On motion car, also have manual mode, and current gear and engine speed;
The name of the phone of telephone number and current access;
The current broadcasting frequency of listening to, and programm name can show in zapping 5 seconds, then hide.
The light source that display system has adopted different colours is looked squarely in the holography that the utility model provides, can show vehicle speed, navigate, turn to, the integrated information such as broadcast, phone, display effect is good, information is comprehensive, experiences intuitively to human pilot.
The embodiment of the above is better embodiment of the present utility model; not with this, limit concrete practical range of the present utility model; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence that all shapes according to the utility model, structure are done changes all in protection domain of the present utility model.
