摘要： The eyepiece of the helmet mounted display optics is formed by a beam splitter eyepiece cube and a spherical mirror to create a magnified virtual image of a rear projection screen mounted to the eyepiece cube at a relatively large distance from the observer. The rear projection screen receives an image from a spatial light modulator display which is illuminated by a separate light source.

摘要： The invention relates to compact optical arrangement for a helmet mounted display. The arrangement is well suited to use with spatial light modulators which require front illumination such as LCoS modulators but can also be adapted to rear illuminated devices such as LCD's and to self luminous devices such as OLEDs. The device uses polarization and reflection to make dual use of both volumes and lenses.

摘要： A first embodiment is a lens system having a plurality of refractive and reflective spherical elements that work as a magnifier to produce a distortion free, less than 1%, image with optical correction over a wide field of view. The system has at least one concave reflecting surface, and at least three convex refracting surfaces with the sign of the radius of one of the convex refracting surfaces being opposite of the sign of the radius of remaining two convex refracting surfaces. A second embodiment is a lens having a concave reflecting element which is on a substrate that is a negative lens by transmission with an index of refraction between 1.6 2.0 and a dispersion 49 15. This is used in combination with at least 3 positive refracting surfaces with less dispersive power than the negative element and with the sign of the radius of one of the positive elements being opposite from the sign of the radius of the remaining positive elements.

摘要： The embodiments herein describe how if a narrow wave length notch of light is used to illuminate or create an image source then the beam-splitter is only required to transmit over the narrow wavelength notch. If the concave mirror only reflects the same wavelength notch then all other wavelengths will pass through the mirror and be reflected by the beam-splitter. Each of the embodiments uses a method of optical design wherein certain portions or elements of the optical system are used for multiple purposes and/or transmit certain paths of light transmission in multiple directions. This use of multiple purposes and multiple paths produces embodiments of the invention that are smaller and more robust.
