Description

Dual-mirror virtual image display for vehicle instrumentation

As this is a public information case, the full text was not included.

1 is a front sectional view schematically showing the virtual image display described.

2 is a front view of a single lens display system to help understand the virtual image display of FIG.

3 is an expanded form of the virtual image display of FIG. 1, and is a front view of the dual lens display to help understand the virtual display of FIG.

Claims (10)

A virtual image display for a vehicle, comprising: an image source for providing imaging illumination, an optical means of a sub-magnification aspherical axis resonating with an image source imaging light for providing divergent imaging illumination, and an imaging illumination from an image source to the eyes of a vehicle driver An optical means of a constant magnification aspherical axis resonating the divergent imaging illumination to provide concentrated imaging illumination that generates a virtual image of the image source observable by the driver of the vehicle at an observation distance greater than the optical path distance driven by the vehicle. And the non-spherical optical means are off-axis, so that the image source and virtual image are not placed on the optical axis of the non-spherical elements, but are non-spherical deformed so as to reduce distortions including distortions generated by the configuration of their axes. Virtual image display. 2. The virtual image display according to claim 1, wherein the image source means comprises a plurality of electromechanical vehicle gauges. The virtual image display according to claim 1, wherein the virtual image is an enlarged image of the source means. 2. The virtual image display of claim 1, wherein the viewing distance is in a range of about 121.92 cm to 365.75 cm (4 to 12 ft). The virtual image display according to claim 1, wherein the sub magnification optical means comprises a sub magnification mirror having a block reflective surface. 6. The virtual image display according to claim 5, wherein the constant magnification optical means comprises a magnification mirror having a convex reflective surface. A virtual image display for a vehicle, comprising: an image source for providing an imaging light, a sub-magnification aspheric off-axis mirror resonating with an image source imaging light for providing divergent imaging light, and an imaging light from the image source to the eyes of the vehicle driver A mirror of a magnification aspherical axis that resonates with the divergent imaging illumination to provide focused imaging illumination that generates a virtual image of the image source observable by the driver of the vehicle at a viewing distance greater than the traveled optical path distance; Since the non-spherical mirror is off-axis, the virtual image display is characterized by non-spherical deformation so as not to lie on the optical axis of the non-spherical elements, but to slow down the distortion including the distortion caused by their off-axis configuration. . 8. The virtual image display according to claim 7, wherein the source means comprises a plurality of electromechanical vehicle instrument gauges. 8. The virtual image display according to claim 7, wherein the virtual image is an enlarged image of the image source means. 8. The virtual image display as claimed in claim 7, wherein the viewing distance is within a range of about 121.92 cm to 365.75 cm (4 to 12 ft). ※ Note: The disclosure is based on the initial application.
