    Abstract: Disclosed is a method of forming an optical monitoring or transmitting light guide and a resulting apparatus that begins by bonding a bundle of optical fibers together using an epoxy and polishing the distal end of the bundle of optical fibers to create an optical aperture. The ratio of fiber size to binder particulate size of the epoxy used in the bonding process is sufficient to maintain the integrity of the bundle of optical fibers during the polishing of the distal end. The method positions the bundle of optical fibers into a protective sheath and a connector. The coefficient of thermal expansion of the epoxy used in the bonding process matches that of the connector. Once assembled, the invention positions the connector through the opening in the surface of a device, such that the distal end of the bundle of optical fibers is either recessed in, substantially flush with, or extends from the surface of the device through which the connector extends, depending on field-of-view requirements.

    Abstract: Sensing elements that quickly and accurately determine if a liquid or gas is present around the sensing elements are disclosed. These sensing elements find particular application in identifying the location of the cavity wall in which a supercavitating vehicle is operating, relative to the vehicle. In certain embodiments signal emitting elements carried on the vehicle emit signals towards the presumed position of the cavity wall, and sensing elements carried on the vehicle receive the emitted signals after they are reflected off of the cavity wall. The sensing elements identify the location where the reflected signal is received, and based on this identified location, the location of the cavity wall is determined. In alternative embodiments, sensing elements are positioned along fins extending outward with respect to the hull of the vehicle, and the sensors sense the presence of liquid or gas.

    Abstract: A damping gyrometer comprised of at least two and preferably four rotating paddles attached to a common central elevated low-friction pivot point via rising radial arms. A stand with a concave glass element provides a low-friction support as a pivot point seat for the pivot point. All elements of the apparatus are non-conductive. Once set into motion, the only force acting on the gyrometer are the pivot point friction and the damping effects of the medium in which it spins. A laser beam and photodetector (or alternatively a laser displacement sensor), along with customized software algorithms are used to measure the rotational rate and, hence, the deceleration rate of the apparatus which can then be used to determine properties of the medium in which it spins, including changes in density, pressure, and temperature. The measurement can also be directly related to the electron density in the case of weakly ionized gases.

    Abstract: The present invention is directed to a hitpoint sensor for a surface of interest, the hitpoint sensor having an optical fiber which is wound around or otherwise covering the surface, and a data processor connected to the ends of the optical fiber. When a collision with the surface occurs, light is generated which passes through the optical fiber. The ends of the fiber are connected to the data processor which uses arrival time information of the light signals arriving at the processor to determine the impact location on the surface. There are several modes in which the processor can operate to make this calculation.

    Abstract: An optical sensor and method for detecting a projectile velocity vector includes optically detecting the arrival of a projectile. The sensor includes a sandwich of a transparent layer within two reflective layers, which in turn are within two opaque layers. An optical sensor structure includes a set of sensors positioned in respective planes, wherein at least two non-parallel optical sensors are used for each trajectory dimension of interest that differs from the primary direction of motion of the projectile and one additional optical sensor may be used for independent measurement of velocity attenuation. An optical sensor structure includes a set of sensors positioned in respective planes, wherein at least two of the optical sensors are oriented in respective planes that are parallel and potentially offset from each other. A tiling of the optical sensors or optical structures is also possible.

    Abstract: A plurality of energy couplers (12) receives signals from an energy pulse, each of the energy couplers (12) having a defined field of view, the field of views of at least some of the energy couplers being overlapping. A transducer (14) converts the signals received from the energy pulse to voltage or current output signals that are then amplified. A threshold circuit (18) triggers when the amplitude of a signal caused by the energy pulse exceeds a predetermined level, and signal processing instrumentation (24) then calculates the source location and/or the intensity and/or the initiation time of the energy pulse based on the timing of the output signals associated with individual energy couplers (12).
