A method and system for temporal dithering of an LED indicator are disclosed, one embodiment of the method comprising: initializing the LED indicator to display a first color of a color palette; during each cycle of a preset cycling rate, cycling the LED indicator display color between the first color and one or more selected colors of the color palette, wherein the LED indicator is caused to display in turn the first color and each selected color of the color palette for a preset portion of each cycle determined to result in a perceived display color at the LED indicator; and repeating the cycling step to maintain the perceived display color at the LED indicator. The method can further comprise the step of changing the perceived display color to a new perceived display color. Changing the perceived display color can comprise: adjusting the size of the preset portion of each cycle allotted to each of the first color and the one or more selected colors for display, wherein the size of each preset portion is determined to result in the new perceived display color; and repeating the cycling step using the adjusted preset portion sizes to maintain the new perceived display color at the LED indicator. Further, changing the perceived display color can be manually initiated or automatically initiated in response to a changing condition.

An optical fiber detector, and a method and system for optical fiber detection are disclosed. One embodiment comprises a receptacle, to receive and position an optical fiber connector, an infra-red (“IR”) source for providing an incident IR beam onto a cross-sectional face of an optical fiber and a cross-sectional face of the optical fiber connector, and an IR detector for receiving a reflected IR beam from the face of the optical fiber and the face of the optical fiber connector and generating a detector signal representative of the intensity of the reflected IR beam, wherein the intensity of the reflected IR beam is representative of the presence and type of the optical fiber. It is contemplated that the optical fiber detector of this invention can be implemented or incorporated in any machine or system requiring connection of an optical fiber to a light source.

An ophthalmic endoilluminator has a power supply coupled to a light source, a controller, a collimation device, an alignment device, a lens, and an optical fiber. The light source has three light emitting diodes. Each of the three light emitting diodes produces a different color light. The controller controls the operation of the three light emitting diodes. The collimation device collimates the light produced by at least one of the light emitting diodes. The alignment device aligns the light individually produced by the three light emitting diodes into a single light beam. The lens focuses the single light beam. The optical fiber for carries the single light beam.

In one aspect of the invention, an ophthalmic endoilluminator includes at least one pump light source and a scintillator fiber optically coupled to the pump light source. The scintillator fiber receives an output of the pump light source and produces light in a different wavelength range than the output of the pump light source. An optical coupling element couples the light to an optical fiber, which conducts the light into an eye.
