Into collimating mirror is a kind of spherical reflector, is ground by glass or plates reflecting layer in shiny surface and is formed, on its focal plane
Object can be into the upright infinity virtual image.Spectroscope is designed to transmissivity and reflectivity be 50% lens, be placed on standard
On the focal plane of straight mirror, after spectroscope, half reflexes to collimating mirror, collimating mirror to the light that such CRT monitor surface sends
About 90% light is reflexed into spectroscope again, again through spectroscope decay 50% after, be only left 22.5% the one-tenth of initial light
It is last effective sunlight, actually last effective sunlight will be less than the 22.5% of initial light, so such display system light
Line loss is lost greatly, causes brightness of image than relatively low.Secondly as belong to coaxial optical system, when observer deviates optical axis farther out,
The pattern distortion seen is only applicable to people's viewing image than larger.Further, because spectroscope can be also reflected in driving cabin
Light, such display system reduces picture contrast by the interference conference of external stray light line.Finally, limited by itself structure
System, such display system angle of visual field is also smaller, and horizontal field of view angle is general not over 50 degree, and vertical field of view angle is not over 35
Degree.Due to its shortcomings, with projector equipment price reduction, progressively substituted by paraxonic virtual image display system.
Existing paraxonic virtual image display system is as shown in figure 3, main by projecting apparatus 8, sphere collimating mirror 1 and rear projection screen

The hard curtain of curved surface, is obtained by mould heat pressure flat organic glass by special coating process treatment, is placed in sphere collimating mirror
On focal plane, the image on rear projection screen is by sphere collimating mirror into the upright infinity virtual image.Due to using off-axis mode, should
Class display system has clear advantage, and sphere collimating mirror radius can reach 3-3.5 meters, and horizontal field of view angle can reach 150-
220 degree, vertical field of view angle can reach 40-50 degree.Compared with coaxial virtual image display system, sphere collimating mirror slant setting is being driven
Before the person of sailing, eyespot not on optical axis, by spheric reflection to driver visual field, and will not work as by veiling glare near cockpit
Pattern distortion is also little when observer's head position is away from optical axis.Rear projection screen diffusion effect in existing paraxonic virtual image display system
Good, light losing is small, and brightness ratio is higher, can be similar to aerial brightness, is widely used in practice at present.
Over time, actual light intensity is constantly changing, and the light intensity of noon will be apparently higher than morning
Above and at dusk.However, existing paraxonic virtual image display system is caused due to Transmission Attenuation when light is by rear projection screen
Light intensity regulating scope is very limited, and its adjustable range can not embody extraneous light intensity and change with time completely, and noon shows
Brightness and morning and brightness at dusk be not different substantially.So, further improve existing paraxonic virtual image display system
The brightness that can be reached, is a problem for urgently needing to solve.In addition, projecting apparatus and ball in existing paraxonic virtual image display system
Face collimating mirror is respectively arranged in rear projection screen both sides, and has relatively long distance between projecting apparatus and rear projection screen, in driving cabin
