Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]

open access: yes, 2015
The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

Infrared thermography at low temperature

open access: yesOptical Measurement Systems for Industrial Inspection XIII, 2023
In the frame of space mission development, the measurement and control of temperature is an important problem for thermal vacuum and thermal balance tests. Replacing a substantial amount of thermocouples by a non-contact thermographic detector is highly desirable.
