Embodiment Construction
[0022] The preferred embodiments provided by the present invention will be specifically described according to the accompanying drawings.
[0023] figure 1 , is a preferred embodiment of a high-precision air display system provided by the present invention. Such as figure 1 As shown, the high-precision air display system includes an image generator 10 for emitting linearly polarized light, and the image generator 10 is obliquely provided with a linear polarization angle for performing linear polarization on the linearly polarized light emitted by the image generator 10. Reflective reflective polarizing film 20, the polarization angle of the linearly polarized light that image generator 10 sends is perpendicular to the polarization angle of reflective polarizing film 20; The incoming linearly polarized light is processed to form a circularly polarized wave plate 30 and is used to retroreflect the circularly polarized light passing through the wave plate 30 so that the retrore...

The invention provides a high-precision air display system. The system comprises an image generator for emitting linear polarized light, a reflecting type polarizing film provided with a linear polarization angle and used for reflecting the linear polarized light emitted from the image generator is arranged at the upper side of the image generator in an inclination way; and the polarization angleof the linear polarized light emitted by the image generator and the polarization angle of the reflecting type polarizing film are perpendicular to each other. Compared with the prior art, the reflecting type polarizing film with the polarization angle reflects the polarized light provided with the linear polarization angle and emitted by the image generator to a wave plate to form circular polarized light, a back-reflecting film reflects back the circular polarized light to the wave plate, and then the wave plate forms the linear polarized light with same polarization angle as that of the reflecting type polarizing film through the back-reflected circuit polarized light, the reflected linear polarized light forms an air imaging picture with high brightness and clear picture after penetrating the reflecting type polarizing film, and the air imaging picture is checked by a looker, and the looker can obtain unprecedented visual experience on the visual experience.
Description
technical field [0001] The invention relates to the field of aerial imaging, in particular to a high-precision air display system and method. Background technique [0002] The current aerial imaging is mostly divided into two forms: the first imaging method mainly adopts Fresnel lens as the main technical support, and uses the principle of Fresnel focusing to focus the multi-angle light sources of the screen on the same focal point. And it diverges in a conical shape, and the viewing angle is within the effective angle range, and the aerial imaging of the left and right eyes and the same focus can be received, but due to the structure of the Fresnel lens itself, the formed image has accuracy, brightness, and reliability. Issues such as viewing range; the second imaging method is to use a retroreflective film to reflect the multi-angle light source of the screen on a semi-transparent and semi-reflective lens to the retroreflective film, and the retroreflective film then retur...
