SYSTEMS AND METHODS FOR OPTICAL TRACKING |
摘要 |
Systems and methods for optical tracking are disclosed. One optical tracking system includes a first optical element configured to focus a light beam and a second optical element configured to redirect the focused light beam from the first optical element. The second optical element is configured to move in order to continuously receive the focused light beam during movement of the focused light beam. Another optical tracking system includes an optical element configured to redirect a light beam and a photosensitive material configured to change its optical properties when it receives the redirected light beam, in order to continuously redirect the light beam during movement of the light beam. The optical tracking methods employ the above-described optical tracking systems.
