Abstract: Optical scanning with an optical probe composed of an elongated cylinder of transparent material mounted upon an optical scanner body; one or more sources of scan illumination mounted in the probe distally or proximally with respect to the scanner body and projecting scan illumination longitudinally through the probe; a radially-reflecting optical element mounted in the probe having a conical mirror on a surface of the radially-reflecting optical element, the mirror oriented so as to project scan illumination radially away from a longitudinal axis of the probe with at least some of the scan illumination projected onto a scanned object; a lens mounted in the probe between the radially-reflecting optical element and the scanner body and disposed so as to conduct to an optical sensor scan illumination reflected from the scanned object.

Abstract: An apparatus is provided that includes an optical probe; and a robotic transport so adapted to the optical probe as to move the optical probe inside a drilled hole to measure the drilled hole at one or more depths.

Abstract: A system for measuring a drilled hole in a structure, the drilled hole having a drilled hole wall, includes a probe having a probe body movable along a probe path extending into the drilled hole, the probe body supporting an optical illumination path and an optical section signal path. Illumination follows the illumination path and is emitted radially outwardly from the probe body so as to illuminate the drilled hole wall when the probe body is disposed at a location along the probe path and the illumination is transmitted along the illumination path. Illumination reflecting from the drilled hole wall back toward an optical sensor represents an optical section signal associated with the location of the probe along the probe path.

Abstract: An otoscanner including a conical laser-reflective optical element and a laser light source and the conical laser-reflecting optical element are configured so that the conical laser-reflecting optical element, when illuminated by the laser light source, projects a broken ring of laser light upon an interior surface of the ear when the ear probe is positioned in the ear and a diffractive laser optic lens and the laser light source and the diffractive laser optic lens are configured so that the diffractive laser optic lens, when illuminated by the laser light source, projects upon an interior surface of the ear a fan of laser light at a predetermined angle with respect to a front surface of the diffractive laser optic lens when the ear probe is positioned in the ear.

Abstract: In the present invention, the solid contacted ISE and the solid contacted reference are based on a conductive porous network with a solid contact and membrane disposed thereon. The porous networks are not only mechanically stable, but also provide pore structure for the solid contact and membrane to intercalate, which enhances the life time and stability of the sensors. The invention further incorporates a unique fluidic fitting sensor and sealing mechanism so that measurements can be taken at high pressures. The fitting design has many benefits, such as low cost and disposability, which allows them to be mass manufactured. These sensors can be produced for detection of many different kinds of ions by applying different types of ion selective membranes, including polyvinylchloride (PVC) based ion-selective membranes and fluorous matrixes based ion-selective membranes.

The resultant laminate material may be tuned for desired sorption rates and selectivities with respect to analytes of interest.
