Abstract: An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75) layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

Abstract: A system for the automated validation of a semi-anechoic chamber (SAC) is disclosed. The system includes a receive assembly and a transmit assembly, each configured to autonomously relocate within the SAC. The system also includes a local client communicatively coupled to the transmit assembly. The local client is configured to send a validation arrangement to the transmit assembly describing a validation location and a distance. The transmit assembly is configured to receive the validation arrangement, move the transmit assembly to the validation location and send an instruction to the receive assembly, the instruction describing the distance. The receive assembly is communicatively coupled to the transmit assembly and configured to receive the instruction and move the receive assembly such that a separation between the transmit and receive assemblies is restored to the distance. Each validation arrangement corresponds to a validation point. A plurality of validation points defines a test volume.

Abstract: A system and method for detecting construction site defects and hazards using artificial intelligence (AI) is provided. The system includes a movable base unit, a coordinate measurement scanner, a vision based sensor, and one or more processors. The one or more processors perform operations that include generating a two-dimensional (2D) map of the environment based at least in part on output from the coordinate measurement scanner, applying image recognition to the video stream data to identify and label a defect or hazard in the video data stream, correlating a location of the defect or hazard in the video stream data with the location in the 2D map, and recording the location of the defect or hazard in the 2D map.

Abstract: A method for ascertaining a distance between a vehicle and a projection surface, onto which a characteristic light pattern is projected using a headlight of the vehicle, includes detecting, in an image of the characteristic light pattern captured by an image capturing unit, a characteristic structure produced by a first light-producing unit by evaluating a geometric location relationship in the captured image between the trajectory and characteristic structures of a characteristic light pattern that are located in an environment along the trajectory; calculating a point on the ray path that is correlated with a position of the detected characteristic structure on the trajectory in accordance with the transformation rule; and calculating the distance between the vehicle and the projection surface from the calculated point on the ray path.

Abstract: An imaging laser range finder including an objective lens having an optical axis, an object side, and an image side, a controllable pixelated light modulator disposed along the optical axis on the image side of the lens, and a detector disposed optically downstream from the pixelated light modulator on the image side of the lens. The controllable pixelated light modulator is advantageously a MEMS-based system such as a digital mirror device (DMD). An increased field of view may be obtained by incorporating a pair of opposing surface reflectors between an imaging lens and the controllable pixelated light modulator. Associated methods are disclosed.

Abstract: An imaging device includes: an image sensor; an imaging optical system; a movable mask; and a second filter. The imaging optical system forms an image of a subject on the image sensor, by using a first optical path and a second optical path involving parallax relative to the first optical path. The movable mask includes a first filter transmitting light in a first wavelength band and a light shielding section, and is movable relative to the imaging optical device. The second filter transmitting light in a second wavelength band different from the first wavelength band is provided in the second optical path.

Abstract: A telescope and beam expander assembly includes a primary telescope mirror. An optical element is spaced apart from the primary mirror. The optical element includes front and rear surfaces, wherein an outward facing aspect of the rear surface is mounted opposite the primary mirror and includes a reflective portion that forms a secondary mirror to reflect gathered light from the primary mirror toward a focal point. An inward facing aspect of the front surface includes a reflective portion that forms a secondary expander mirror configured to reflect a beam onto an inward facing aspect of the rear surface for beam expansion. The optical element can include a monolithic body of optically-transmissive material on which the front and rear surfaces are located.
