See-through optical system
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.
