Abstract: An optical fiber detector (24), and a method and system for optical fiber detection are disclosed. One embodiment of the optical fiber detector of this invention comprises: a receptacle (50), to receive and position an optical fiber connector (32); an infra-red ("IR") source (36) for providing an incident IR beam onto a cross-sectional face of an optical fiber (34) and a cross-sectional face of the optical fiber connector; and an IR detector (46) 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.

Abstract: A continuous high resolution fluid level monitoring system (300) is provided by embodiments of the present invention. This continuous high resolution fluid level monitoring system includes a unique fluid level sensor having a point light source (202), parabolic reflector (204), sensor array (308), and detection, processing and control system (310). The point light source illumines a parabolic reflector wherein the point light source is located at the focus of the parabolic reflector. The parabolic reflector reflects light from the point light source to produce a parallel light curtain (210). This parallel light curtain is parallel to an axis of symmetry of the parabolic reflector. The parallel light curtain illumines a chamber (302) such as a chamber in an ophthalmic surgical device used to contain surgical fluid (304). The sensor array coupled to the chamber detects the parallel light curtain illuminating the chamber. The sensor array provides an output to a detection/processing/control system in order to determine the fluid level within the chamber. This optical method of determining the surgical fluid levels may be advantageous in that it prevents physical contamination of the surgical fluids.
