  • Publication number: 20070156021
    Abstract: Systems and methods for making and using endoscopes comprising one or more fluid lenses. An endoscope or bore-scope for various highly accurate imaging, visual inspection and measurement applications is equipped with an adaptive lens operated based on the electrowetting or electro-capillarity phenomenon. The adaptive lens is digitally controlled and is able to provide auto-focusing and optical zooming functions while remaining in a stationary position relative to a distal end section of the endoscope. Endoscopes equipped with these adaptive lenses provide a simpler, more compact design and a faster response while providing high quality images. Several functions needed in a variety of endoscopic imaging, inspection and measurement applications are further enhanced through the addition of a number of improvements of the adaptive lens itself and of the systems incorporating the adaptive lens.

  • Publication number: 20060072903
    Abstract: A system and method for storing, within an image transfer medium, an image and image-specific data associated with the image includes obtaining the image-specific data from a probe such as a borescope or endoscope, obtaining the corresponding image, choosing a specific image transfer medium, writing the image to the medium, and writing the image-specific data to a marker in the medium. In this manner, storing a combination of image data and one or more of system calibration data, overlay replacement data, and audio comment data in a single file of either a non-standard file format or a standard file format that does not explicitly support the inclusion of these data types is possible.
