Abstract: Provided is a gyroscope stabilized gimbal assembly for collecting and timestamping video data and laser measurement data. The assembly can be used on multiple platforms and provides an ISR video camera system and one or more laser measurement devices, including photodetectors, thermopiles, filters, and analog to digital converters. The components are mounted to a bracket that can be installed and removed from the assembly to collect/record measurement data from the devices interacting with the laser beam. A processor collects and records measurement data from the devices interacting with the laser beam and calculates optical power data, irradiance data, and wavelength data. A storage device stores a first set of data comprising video data from said camera system and a second set of data comprising optical power data, irradiance data, and wavelength data, wherein said first and second set of data are timestamped, separated, and not comingled.

Abstract: Provided is a broadband multi-line laser beam combiner apparatus and method that allows a broader spectrum of light to be emitted from a single optical path. The disclosed apparatus and method provide the ability to combine a number of unique laser lines including both visual and infrared light as one optical beam that is emitted from a single emission aperture or window using both conventional dichroic mirrors and an imaging dichroic mirror. The apparatus and method are based, in part, on an optical material selection and design that affords the ability to combine multiple broadband laser sources. Rather than merely emitting discrete laser lines, the presently disclosed broadband multi-line laser beam combiner can emit an “ultra-wide-continuum” of wavelengths from approximately 400 nm to 5000 nm at emitted optical powers greater than five (5) Watts from one emission aperture/window.

Abstract: In order to locate, trace, and identify hidden elongated objects, such as buried fiber optic cables, the objects are provided with elongated permanent magnet identifier devices having magnetic fields that may be detected at a distance from the objects. In one embodiment the identifier device comprises an elongated strip magnetized in the direction of its width and formed into a long-pitch helix, producing a characteristic "magnetic field signature" that enhances detection and identification of the object, as by a portable gradiometer that is moved over the surface of the earth along a line generally parallel to the length of the object. This embodiment may provide a magnetic field that diminishes as the square of the distance from the identifier device (rather than the usual cube of the distance), thereby enabling detection at substantial distances.
