DEFLECTION DEVICE FOR LISSAJOUS SCANNING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18316733 titled 'DEFLECTION DEVICE FOR LISSAJOUS SCANNING
Simplified Explanation
- The patent application describes a deflection device for Lissajous scanning. - The device includes a frame and a mirror that can move within the frame. - The mirror is suspended by one or more springs, allowing it to swing back and forth about two or three axes. - This swinging motion reflects incoming light at different angles, creating a two-dimensional Lissajous pattern. - The device also includes a driving device that can excite the mirror's swing motion at or near its eigenfrequency. - The springs have a specific shape that covers more than 360 degrees along the circumference of the mirror. - This arrangement of the springs provides a compact suspension for the mirror and allows for larger tilt angles.
Original Abstract Submitted
A deflection device for Lissajous scanning is provided. The deflection device includes a frame and a mirror. The mirror is movably arranged in a recess in the frame by means of a suspension mount including one or more springs. The mirror may be configured to swing back and forth about each of two or three axes with a respective eigenfrequency for reflecting incoming light at different angles to form a two-dimensional Lissajous pattern. The deflection device may include a driving device configured to excite swing motion of the mirror about each of the two or three axes at or near the respective eigenfrequency. Each of the one or more springs has a shape of a path segment along a circumference of the mirror together covering more than 360 degrees. An arrangement of the one or more springs provides a compact suspension for the mirror and larger tilt angles.
