Flight based infrared imaging systems and related techniques, and in particular UAS based thermal imaging systems, are provided to improve the monitoring capabilities of such systems over conventional infrared monitoring systems. An infrared imaging system is configured to compensate for various environmental effects (e.g., position and/or strength of the sun, atmospheric effects) to provide high resolution and accuracy radiometric measurements of targets imaged by the infrared imaging system. An infrared imaging system is alternatively configured to monitor and determine environmental conditions, modify data received from infrared imaging systems and other systems, modify flight paths and other commands, and/or create a representation of the environment.

Unmanned aerial system based thermal imaging and aggregation systems and methods

Various techniques are provided to monitor electrical equipment. In some implementations, a monitoring system for a cabinet may include an infrared camera and a non-thermal camera. The infrared camera may be configured to capture one or more thermal images of at least a portion of electrical equipment positioned in an interior cavity of the cabinet. The non-thermal camera may be configured to capture one or more non-thermal images such as visible light images of the portion of electrical equipment. In some implementations, combined images may be generated that include characteristics of the thermal images and the non-thermal images for viewing by a user. In some implementations, the cameras may receive electrical power through a physical coupling to an electrical connector within the cabinet and/or through electromagnetic energy harvesting techniques. Other implementations are also provided.

In some implementations, a monitoring system for a cabinet may include an infrared camera configured to capture thermal images of at least a portion of electrical equipment positioned in an interior cavity of the cabinet. In some implementations, the monitoring system also includes a communication interface configured to transmit the thermal images from the infrared camera for external viewing by a user. In some implementations, the thermal images may be provided through various wired and wireless communication techniques. In some implementations, the infrared camera may receive electrical power through a physical coupling to an electrical connector within the cabinet and/or through electromagnetic energy harvesting techniques. Other implementations are also provided.

Electrical cabinet infrared monitor

An infrared camera system is provided to detect absorption of infrared radiation in a selected spectral bandwidth. In one example, an infrared camera system includes a lens adapted to receive infrared radiation from a survey scene comprising one or more gasses. The infrared camera system also includes a focal plane array comprising a plurality of quantum well infrared photo detectors (QWIPs). The QWIPs are tuned to detect a limited spectral bandwidth of the infrared radiation corresponding to at least a portion of an infrared absorption band of the one or more gasses. The infrared camera system also includes an optical band pass filter positioned substantially between the lens and the focal plane array. The optical band pass filter is adapted to filter the infrared radiation to a wavelength range substantially corresponding to the limited spectral bandwidth of the QWIPs before the infrared radiation is received by the focal plane array.

A portable camera system () includes a lens () for forming a focused image of a survey scene () onto a focal plane array (). The focal plane array () comprises a cooled two dimensional array of quantum well infrared photo detectors, (QWIP) having a peak spectral responsivity in the wavelength range of 10.4 to 10.8 &#x3bc;m. The camera includes a cooled band pass optical filter () having a peak spectral transmittance approximately centered at a wavelength of 10.57 &#x3bc;m and a full width half maximum spectral transmittance bandwidth of approximately 10.3 to 10.7 &#x3bc;m. The camera system () is usable to detect an invisible gas plume in a video image of a survey scene if the gas plume contains sulfur hexafluoride (SF), ammonia, (NH), Uranyl Fluoride (UOF), or any other gas having an absorption band that that at least partially falls within the wavelength band 10.3 to 10.8 &#x3bc;m.

Thermography camera configured for leak detection

The disclosure describes a device for continuous analog position control of multiple torque receivers by a single low power synchro signal source. The device provides continuous control of the magnitude and direction of current flow between the stators of the controlled torque receiver(s). The current flow produces torque which moves the rotor(s) to the desired position.
