MEMS DEVICE WITH ELLIPTICAL MIRROR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240295742 titled 'MEMS DEVICE WITH ELLIPTICAL MIRROR
The patent application describes optical systems that incorporate MEMS mirrors with elliptical mirror plates. These systems may include a laser scanning system with a MEMS mirror that scans light along a single axis.
- The MEMS mirror has an elliptical mirror plate with a semi-major axis aligned parallel or perpendicular to the rotational axis.
- The incident light beam has an elliptical cross-section, ensuring complete or substantial overlap with the mirror plate's reflecting surface.
- After reflection, the light beam is circularized by shaping lenses in its optical path before projection.
Potential Applications: - Laser scanning systems - Optical communication systems - Medical imaging devices
Problems Solved: - Efficient scanning of light beams - Precise control of light direction - Improved image quality in optical systems
Benefits: - Enhanced scanning accuracy - Reduced optical aberrations - Compact and lightweight design
Commercial Applications: Title: Advanced Laser Scanning Systems for High-Precision Applications This technology can be used in industries such as: - Biomedical imaging - Industrial manufacturing - Aerospace engineering
Questions about the Technology: 1. How does the elliptical mirror plate improve the performance of the MEMS mirror? The elliptical shape allows for precise control and manipulation of the incident light beam. 2. What are the advantages of circularizing the light beam before projection? Circularization helps improve image quality and reduce optical distortions.
Original Abstract Submitted
optical systems may include mems mirrors having elliptical mirror plates. a laser scanning system may include a mems mirror that scans an incident light beam along a single scanning axis. the mems mirror may include an elliptical mirror plate having a semi-major axis that is aligned parallel or perpendicular to the rotational axis of the elliptical mirror plate. the incident light beam may have an elliptical cross-section, such that the incident light beam completely or substantially overlaps the reflecting surface of the elliptical mirror plate. after being reflected by the elliptical mirror plate, the light beam may be circularized via one or more shaping lenses disposed in the optical path of the reflected light beam, prior to projection of the light beam.
