Abstract: An optical tissue imaging system includes a probe for insertion into a transparent cylindrical capillary. The capillary includes an internal cylindrical channel that extends along a central axis. The capillary is inserted into tissue of a subject, and the probe may rotate and translate within the capillary. The probe may include a mirror configured to reflect light to the tissue outside of the cylindrical capillary.

Abstract: The MCP assembly of this embodiment is formed at least of a conductive upper support member, an MCP unit, an output electrode, a flexible sheet electrode, and a conductive lower support member as a structure for improving handleability of a flexible sheet electrode having a mesh area. The flexible sheet electrode includes the mesh area provided with plural openings. The flexible sheet electrode and the lower support member are physically and electrically connected to each other, and the flexible sheet electrode is sandwiched between the upper support member and the lower support member. As a result, even if the flexible sheet electrode becomes thin as an opening ratio of the mesh area increases, potential is set while the flexible sheet electrode is firmly held in the MCP assembly.

Abstract: The present invention provides for very fast detection of gaze direction using retro-reflected light from the ocular fundus that is cost-efficient, small, and portable. These eye trackers are useful in many areas of science and technology, including but not limited to remote control, space, defense, medical and psycho-physiological applications, to identify for example subtle neurologic deficits that occur with cerebellar or vestibular disorders, Parkinson's disease, strokes, traumatic brain injury, possible concussions during sports matches, some forms of reading disability, or simply fatigue or inebriation. In ophthalmology, with two such devices operating simultaneously, the variability of relative eye alignment over time can be measured, without requiring individual calibration, and without requiring fixation on a specified target, ideal for use with small children. Such instruments have widespread application as noninvasive screening devices in infants and young children or patients of any age for defects of binocular function such as strabismus and amblyopia.

Abstract: The disclosure is directed to a photomultiplier tube with extended dynamic range. According to various embodiments, a repulsive electric field is introduced between a photocathode and a plurality of dynodes in order to repel or block low-energy electrons from reaching and being multiplied by the dynodes. As a result, time intervals between current peaks and drops may be decreased because the photomultiplier current will be primarily affected by high-energy electrons emitted by the photocathode in response to incident illumination versus low-energy electrons, some of which may result from dangling bonds or slow surface states after illumination no longer impinges the photocathode. Dynamic range and optical responsiveness of the photomultiplier tube are increased accordingly.

Abstract: A faceplate (F) for an image intensifier tube (10) for reducing veiling glare begins as a blank (36) of optical material of a desired glass composition having a shape that conforms substantially to a configuration of the faceplate (F) to be produced. An extraneous removable aperture step portion (54) is formed on the glass blank (36). The glass blank is blackened (41) and the aperture step portion (54) is removed creating a desired transmissive aperture (34) through the glass blank (36).

Abstract: A method of manufacturing an imaging component is provided comprising placing a focusing device in between a laser generator and a scintillator element; generating a laser using the laser generator; focusing the laser using the focusing device such that a focal spot of the laser is coincident with a portion of the isotropic portion; using the laser to alter the optical properties at the focal spot such that anisotropy is generated in the isotropic portion; and moving the focal spot relative to the scintillator element such that a three-dimensional pattern with altered optical properties is generated. The three-dimensional pattern controls the spread of photons within the scintillator element.
