20090270683 | ENDOSCOPE - Improved optical devices and methods transmit optical images along elongate optical paths with relatively limited cross-sectional dimensions using an improved objective, relay, and ocular systems. In a first aspect, at least one intermediate image formed within an optical component, rather than being formed in a gap between optical components. In a preferred embodiment, a first intermediate image is formed within glass of the most proximal objective lens, with the first intermediate image extending axially along a curved image location within the glass. The last intermediate image may similarly be disposed within a distal lens of the ocular system. By making use of a first and/or last intermediate image disposed in this manner within a lens, endoscopes can exhibit a significantly larger Numerical Aperture than known endoscopes having similar cross-sectional dimensions. In a second aspect, the ocular system allows independent adjustment of diopters, magnification, X-Y positioning, and rotation orientation of the captured image while introducing minimal aberrations. | 10-29-2009 |
20100274089 | LAPAROSCOPE AND SETTING METHOD THEREOF - A laparoscope includes: a housing extending a particular length; a pair of lenses set in both end portions of the housing along a lengthwise direction; a pair of first reflectors mounted within the housing adjacent to the pair of lenses to reflect light from the pair of lenses towards a particular position; a second reflector mounted within the housing that receives the light reflected from the pair of first reflectors and reflects the light in a particular direction; and an optical passage coupled to the housing that receives the light reflected from the second reflector and transmits the light to a particular position. Since a single-lens laparoscope may be connected to the housing where a pair of lenses are set with a gap in-between, the diameter of the laparoscope can be reduced, and an image can be obtained that has a brightness comparable to that obtained by a single-lens laparoscope. | 10-28-2010 |

20120184819 | ENDOSCOPE - Improved optical devices and methods transmit optical images along elongate optical paths with relatively limited cross-sectional dimensions using an improved objective, relay, and ocular systems. At least one intermediate image is formed within an optical component. For example, a first intermediate image is formed within glass of the most proximal objective lens, with the first intermediate image extending axially along a curved image location within the glass. The last intermediate image may similarly be disposed within a distal lens of the ocular system. The ocular system allows independent adjustment of diopters, magnification, X-Y positioning, and rotation orientation of the captured image while introducing minimal aberrations. | 07-19-2012 |
20120190928 | DOUBLE CLAD FIBER COUPLER AND DEVICE - There is described a double-clad fiber coupler (DCFC) composed of two double-clad fibers that have been fused together and tapered. The DCFC allows the propagation of light in the fundamental mode in its single-mode core with very little loss. Back reflected light may be collected two ways: by the core of the double-clad fiber and by the inner cladding of the double-clad fiber. | 07-26-2012 |
20130023732 | ENDOSCOPE AND ENDOSCOPE SYSTEM - An endoscope system and an endoscope includes a patterned light providing unit to provide patterned light having a pattern corresponding to a feature point; first and second capturing units to capture an object onto which the patterned light is irradiated; and a light transmitting unit to transmit the patterned light to the object and transmit light reflected by the object to the first and second capturing units. | 01-24-2013 |
20130041226 | IMAGE CAPTURE UNIT IN A SURGICAL INSTRUMENT - In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field. | 02-14-2013 |
