  • Patent number: 8988648
    Abstract: Techniques are disclosed for creating optical systems and devices that provide through-sight information while enabling the optical systems and devices to maintain a small, lightweight form factor. According to certain embodiments of the invention, an optical assembly can include a liquid-crystal display (LCD) disposed between the two prism elements of a Schmidt-Pechan prism at a focal plane of the optical assembly. This allows the LCD to be used to display information by blocking light passing through the optical assembly. Additionally, a light-emitting display, such as a backlit LCD, light-emitting diode (LED) display, or organic LED (OLED) display, can be coupled at a surface of one of the two prism elements of the Schmidt-Pechan prism to provide additional information in low-light environments.
