Towards Airborne Thermography via Low-Cost Thermopile Infrared Sensors

Heat flux sensors and infrared thermography

Low-Cost Airborne Thermal Sensors for Animal Monitoring

Background Vertebrate pests are a major environmental and economic threat in New Zealand. One of the species that has high potential threat is possum (Trichosurus vulpecula). The direct environmental impacts of possum are in defoliation of native flora and predation of native birds (Montague 2000). The direct economic impact is a result of their role as vectors of bovine tuberculosis (Tb). New ...

Understanding Thermopile Infrared

The thermocolumn or thermopile comprises a series of thermoelements, each element being a thin wire made of two materials of different thermal activity. When a temperature difference occurs between the two ends of a wire, an electrical tension thermotension, develops. Connecting several thermoelements in series adds together the thermotension of each element, producing a useful electrical outpu...

Heat Flux Sensors for Infrared Thermography in Convective Heat Transfer

This paper reviews the most dependable heat flux sensors, which can be used with InfraRed (IR) thermography to measure convective heat transfer coefficient distributions, and some of their applications performed by the authors' research group at the University of Naples Federico II. After recalling the basic principles that make IR thermography work, the various heat flux sensors to be used wit...

Low Cost Multimodal Facial Recognition via Kinect Sensors

Biometrics is a key technology that can help identify friend from foe and deny the enemy anonymity he needs to hide and strike at will. Biometrics is defined as a measurable biological (anatomical and physiological) and behaviour characteristics that can be used for automated recognition [1]. The military needs reliable methodologies to enable it to identify people who are or might be national ...
