متن کاملDetermining the Leaf Emissivity of Three Crops by Infrared Thermometry
Plant temperature can provide important physiological information for crop management. Non-contact measurement with an infrared thermometer is useful for detecting leaf temperatures. In this study, a novel technique was developed to measure leaf emissivity using an infrared thermometer with an infrared sensor and a thermocouple wire. The measured values were transformed into true temperatures b...
متن کاملVelocity Navigator Triggering for Motion Compensated PRF Thermometry
Introduction MR-guidance is increasingly used for thermo-therapies such as radio frequency, laser (LITT) or focused ultrasound ablation, because MR allows for non-invasive temperature measurements. In the most commonly applied proton resonance frequency (PRF) shift thermometry, temperature differences are calculated based on phase variations with respect to a reference baseline. Since there is ...
متن کاملInAs Photodiodes for 3.43 μm Radiation Thermometry
We report an evaluation of an epitaxially grown uncooled InAs photodiode for the use in radiation thermometry. Radiation thermometry measurements was taken using the photodiode covered blackbody temperatures of 50 °C–300 °C. By determining the photocurrent and signal-to-noise ratio, the temperature error of the measurements was deduced. It was found that an uncooled InAs photodiode, with the pe...
متن کاملEstimation of Ambient Radiation Temperature for Emissivity-corrected Thermography
A non-contact method for the measurement of emissivity, and emissivity-corrected temperatures has been developed, where the ambient radiation-temperature is changed in a discontinuous way. When the ambient radiation-temperature is changed quickly, so that the surface temperature of the object can be assumed to be unchanged, the radiometer output before, and immediately after that change can be ...
