Abstract
The present patent application aims to teach imaging apparatus, methods, and systems for providing a laser safety interlock for at least one optical probe in the apparatus. The interlock mechanism ensures the lasers are off when the optical probe is not spinning to reduce the laser hazard.
Claims18
Optical imaging apparatus comprising:
- an imaging engine having at least one laser source and a controller for controlling the laser source;
- a patient interface unit comprising:
- a rotational motor;
- rotary joint;
- and
- a probe connection;
- and
- a probe comprising an optical fiber to illuminate a laser light from the at least one laser source;
- wherein the probe is rotated by the rotational motor when imaging;
- and
- wherein the laser light is functional only when the probe is rotating.
