摘要： A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation are disclosed. One embodiment of the apparatus comprises: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a means for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame. The means for rotating the fin plate would then comprise means to rotate the attenuator frame. Means for rotating the attenuator fin plate or frame can include a stepper motor, for discrete step positions, or a continuously variable motor for infinitely variable positioning. The means for rotating the attenuator fin plate or frame can be electronically controlled, for example, by a microprocessor on a printed circuit board or other such controller as known to those having skill in the art. The preset fin angle can be 31 degrees, and the preset fin plate angle can be 90 degrees. Each of the attenuator fins can be operably coupled to the fin plate at the same preset fin angle and the fin plate and/or frame centered on the axis of rotation. Each fin's major axis can be parallel to every other fin's major axis, and the axis of rotation can be parallel to each fin's major axis. The set of attenuator fins can comprise eight attenuator fins and the attenuator fins can be spaced equally apart from one another. The attenuator fin plate and set of attenuator fins can be sized so as to interfere with the entire light beam cross-section/aperture at a position along the set angular distance corresponding to zero percent of the optical beam passing through the attenuator fins. The embodiments of the attenuator of this invention can be configured for use within an ophthalmic high brightness illumination system.

摘要： An optical fiber detector, and a method and system for optical fiber detection are disclosed. One embodiment of the optical fiber detector of this invention 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. This embodiment of the optical fiber can further comprise an IR filter for filtering non-IR wavelengths from the reflected IR beam before the IR beam is received at the IR detector and signal processing and control means, for receiving and processing the detector signal to provide display, control or monitoring functions. The receptacle can be part of an illuminator system enclosure housing a light source, wherein the receptacle is further operable to position the connector such that the optical fiber is optically coupled to the light source. The infra-red source can comprise an IR light emitting diode (“LED”) and the IR detector can comprise a photodiode operable to detect IR wavelengths. The intensity of the reflected IR beam can vary, and is inversely proportional to the ratio of the area of cross-sectional face of the optical fiber reflecting the incident IR beam to the area of cross-sectional optical fiber connector reflecting the incident IR beam. Embodiments of this invention can be implemented within any fiber-optic illuminator machine or system for use in ophthalmic or other surgery. Further, 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. Other uses for an optical fiber detection method and system designed in accordance with the teachings of this invention will be apparent to those familiar with the art.

摘要： A system and method for non-invasive pressure sensing are disclosed. One embodiment of the system is an assembly comprising: a plurality of coherent light sources, wherein the plurality of coherent light sources are located in a fixed relationship to one another; an image sensor; and a pressure chamber, comprising a flexible diaphragm, the flexible diaphragm configured to flex in response to a change in pressure in the pressure chamber and operable to reflect a beam of light originating from each of the plurality of coherent light sources onto the image sensor. The pressure sensing assembly can further comprise a processing module operably coupled to the plurality of coherent light sources and to the image sensor and a memory operably coupled to the processing module, wherein the memory includes operational instructions that cause the processing module to carry out the steps of an embodiment of the method for non-invasive pressure sensing of this invention. Such a method can comprise the steps of: directing the plurality of coherent light beams, at a known incidence angle, onto the flexible diaphragm, wherein the plurality of coherent light beams form a pattern of light spots on the diaphragm; capturing at the image sensor an image of the light spot pattern reflected from the diaphragm, wherein the light spot pattern is indicative of the pressure within the pressure chamber; and determining the pressure within the pressure chamber from the captured light spot pattern of the image. The pressure sensing assembly can further comprise a fluidics interface operably coupled to the processor for receiving instructions from the processor to control fluid flow in a fluidics system coupled to the pressure chamber. Such a fluidics interface could be, for example, part of a surgical system, such as an ophthalmic surgical system, incorporating an embodiment of the present invention. The pressure sensing assembly can also comprise a calibration interface for providing calibration inputs to the processor.
