Description
Technical field
The invention relates to a kind of projection arrangement, refer in particular to a kind of being applicable to and make running information video picture refraction projection device more clearly.
Background technology
The heavily security of head of travelling of motor vehicles, however no matter the automobile or the running information of locomotive are arranged on the instrument panel often, when driver's desire captures above-mentioned information, must be noted that the situation of driving simultaneously, therefore then be easy to produce dangerous.
Existing at present at the designed data projection arrangement of car steering person, if when being applied on the locomotive, it then is an appropriate position that is mounted on the locomotive apparatus, but because the locomotive driving person is in an open space, the rocking property that is produced between travelling is higher, if meet extraneous light when strong, sunray for example, then the running information of projection arrangement institute video picture just becomes fuzzyly easily, makes the driver can't know acquisition.In addition, automobile is when running at high speed (vehicle of for example competing for speed), and the driver also often wears the head-shield or the helmet with protection driver safety, also needs this moment the data projection arrangement so that the driving instant messages to be provided, and protects driver's safety simultaneously.And present helmet-type display device mostly is and is built among the head cap or the helmet, if the user has a mind to use, then needs additionally to buy the head cap or the helmet that new design has the built-in projection arrangement of arrangement, its material comparatively waste and cost higher.For near the cap body that does not have the lower edge extensional shell some user's mouth, built-in projection arrangement also is not easy to install in addition, that is present built-in projection arrangement use elasticity is low, needs badly and will be improved.
At automobile or the designed data projection arrangement of locomotive driving person, mostly be the projection arrangement of direct projection at present, it is big to take up room, and assembling is inconvenient, and need expend a large amount of electric powers.And tradition uses the projection real image in ocular imaging, and its enlargement factor is if desire promotes, and the distance that then needs to elongate projecting mirror group and eyeball so if desire strengthens the image enlargement ratio, then needs to strengthen the shared space of optical projection system, in fact also impracticable.In addition, this forms the display device of projection real image in eye, when user's head moves (for example driving the operation of traffic with steam turbine car or simulation), can produce because the image fog that ghost and Du Bule effect cause or seriously rock, so display quality is not good, application is wideless.
See also Fig. 1 (A) to 1 (E), this is the synoptic diagram of known Doppler effect in the human eye effect.As same employed video recorder of many people at present or camera, when in user's hand held camera is moving, attempting focusing, the camera lens of meeting discovery camera is adjusted its focal length always in front and back, this be because camera which must be attempted putting in order actually partly is institute's desire main body of taking, this main body apart from distance of camera or the like, could correctly focus and take clearly image.Human eyes are as the camera lens of camera, and the length of curvature, axis oculi that must adjust crystalline at any time apace is to adapt to the scenery of different distance.
Shown in Fig. 1 (A), when eyes finding object image is static real image 6, eyeball 5 maintains normal state with crystalline 51: then see also Fig. 1 (B), when being in one, real image 61 and eyeball 501 relatively move when middle, eyeball 501 is for catching correct image so the length of necessary rapid adjustment axis oculi and the curvature of crystalline 511, diminish and become comparatively flat as crystalline 512 curvature in Fig. 1 (C), and the axis oculi length of eyeball 502 shortens for the curvature that adapts to crystalline 512; Perhaps the curvature as crystalline 513 among Fig. 1 (D) becomes big and the comparatively thick circle that becomes, and the axial length of eyeball 503 is elongated for the curvature that adapts to crystalline 513; At last, shown in Fig. 1 (E), crystalline 514 is adjusted to a correct curvature, and axis oculi is also adjusted to 504 state thereupon.In the middle of the process of adjusting,, therefore have the generation of image retention 62 because the speed of movement of objects is higher than the speed that eyeball is adjusted, that is known Doppler effect.And, in the process of rapid adjustment focal length, blood capillary around the eyeball blood that circulates in a large number can be given the eyeball build-up of pressure, and the intraocular pressure of adjusting under the focal length for a long time, continually to be caused is too high not only can to form uncomfortable sensation to human eye, and severe patient more probably has the possibility of detached retina.
What is more, light scattering loss height in its projection optical path, so the light service efficiency is low, light loss is big.Therefore, still need a kind of new display device in the market, the image that can effectively amplify micro-display and provided, and keep high-res, its formation method can oppression eyeballs, can be closely, the long-time use also can not cause the eyes malaise symptoms.
