Optical tracking system using variable focal length lens
First Claim
1. An optical system comprising at least one camera system, the at least one camera system including:
- an objective lens system, configured to receive an object image;
at least one micromirror array lens, optically coupled to the objective lens system, configured to focus the object image received by the objective lens system onto an image sensor; and
the image sensor, optically coupled to the micromirror array lens, configured to receive the focused object image from the micromirror array lens and to sense the focused object image.

Abstract
An optical tracking system using a variable focal length lens includes at least one camera system, and the at least one camera system includes an objective lens system, configured to receive an object image, and at least one micromirror array lens, optically coupled to the objective lens system, configured to focus the object image received by the objective lens system onto an image sensor. The image sensor is optically coupled to the micromirror array lens, configured to receive the focused object image from the micromirror array lens and to sense the focused object image. The advantages of the present invention include ability to rapidly change the focal length and optical axis of a camera system, allowing for high-resolution, wide-angle imaging.
