Projection Device Imaging Module with Movable Optical Element

The patent applies the dynamics principle by making the optical element movable through an image displacement device with actuators. The optical element can swing between different positions, allowing the system to dynamically adjust the optical path. This enables high-resolution imaging without requiring permanently large components, as the movable configuration allows compact packaging while maintaining imaging quality during operation.

The patent utilizes dimensional change by transitioning the optical element from a fixed linear arrangement to a movable configuration that exploits angular displacement. The optical element swings along an arc path, effectively using angular dimension to achieve compact optical path folding. This allows the optical system to fit within a smaller volume while maintaining the necessary optical path length for high-resolution imaging.

The patent applies universality by designing the movable optical element to serve multiple functions simultaneously. The same optical element that provides high-resolution imaging also enables optical path folding and compact system packaging through its movement capability. The actuator system not only positions the optical element but also enables the entire system to achieve high resolution without requiring separate dedicated components for each function.

The patent merges multiple functions into a single integrated movable optical element system. Rather than using separate fixed components for imaging, beam steering, and path folding, the patent combines these functions into one movable optical element controlled by actuators. This consolidation reduces the total number of components while achieving high-resolution imaging in a compact configuration.
