Abstract: An otoscope includes an instrument head, a tip element and an optical system. The instrument head has a distal insertion portion for insertion into an ear of a human or veterinary subject. The distal insertion portion has a distal opening. The tip element is releasably attached to the distal insertion portion. The tip element has a distal opening. The optical system is contained within the instrument head. The optical system includes a plurality of optical components. The optical system further comprises a viewing component for viewing of an image of a target of interest aligned along an optical axis disposed within said distal opening. The optical system is configured to provide a field of having a diameter equaling at least 7 mm at a distance of at least 15 mm from a distal opening of said attached tip element. The optical system is further configured to simultaneously provide a distance range of optimal focus having a range of at least 8 mm. The distance range of optimal focus includes a location at a working distance equal to about 30 mm.

Abstract: A system automatically captures a fundus image with limited user interaction such that the fundus image has one or more desired characteristics. The system can retrieve at least one image from an image capture device, process the at least one image digitally to generate a processed image, detect at least one point of interest in the processed image, determine that each of the at least one point of interest is representative of a corresponding feature of the eye, and obtain a fundus image of the eye based on the at least one image.

Abstract: A medical diagnostic instrument includes a housing having an interior, a distal end and an opposing proximal end. A supporting member is disposed within the interior of the housing, and supports a plurality of LEDs. A light guide made from a light transmissive material is distally disposed in relation to the LED supporting member for transmitting light emitted by the plurality of LEDs through the distal end of the housing. In at least one version, at least one end of the light guide can be provided with a patterned surface that is configured to produce a uniform illumination spot.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, a method for aligning first and second light signals on an optical path directed to a target, where the first light signal provides a visualization of the target, and a portion of the second light signal reflects from at least one subsurface of the target. The method also includes aligning a first focal point of the first light signal and a second focal point of the second light signal, where the first focal point is at least in a first proximate location of the second focal point, and adjusting a first position of the first and second focal points to be in at least a second proximate location of the target without adjusting the at least first proximate location of the first focal point relative to the second focal point. Other embodiments are disclosed.
