Easy-to-manufacture autoclavable led for optical tracking

An optical tracking system is provided. The optical tracking system includes an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel with the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system also includes a tracking device including at least two optical sensors configured to detect a position of light emitted by the light source. The system also includes a processor configured to receive the positions of the light rays from the optical sensor, move the position of each light ray based on the calculated refractive deviation, and triangulate the location of the light source based on the moved position of each light ray. 提供了一种光学跟踪系统。所述光学跟踪系统包括可高压灭菌基准标记组件，所述可高压灭菌基准标记组件包括不透明壳体、光源、被构造成折射来自光源的穿过其中的光线的窗面板、以及在所述窗面板与所述不透明壳体的相接部处形成气密密封的金属化涂层
