Wide Field of View Substrate Guided Relay

摘要

A substrate guided relay includes multiple output couplers and multiple light valves positioned between the substrate and the output couplers. The number of light valves may be equal to the number of output couplers, or may be more or less than the number of output couplers. The light valves may be enabled sequentially, or may be enabled based on the position of a user's eye. The light valves may include liquid crystal material.
