Description
Thermal radiation is omnipresent, radiated by any object in the universe, including universe itself. For a long time, Planckian radiation was used as a reliable “fingerprint” of a thermal state of a matter – human body, homes, industrial objects and, regrettably, weapons, among many other things [1]. Here we provide an overview of thermal measurements in biophotonics in order to study how life maintains favorable thermal state enabling survival in the environment. We will present how micron and submicron sized structures may influence emission and absorption of radiation.
Insects are extremely interesting in that respect, because they have developed diverse and efficient mechanisms to sustain optimal temperature of their bodies. Many of them, such as ants (Formicidae) [2] and beetles (Coleoptera) [3], developed micro/nano structures to dissipate thermal energy and maintain life supporting conditions within extreme environments. We will present how elytra (modified, hardened wings, enveloping Coleoptera body) have been evolutionary adapted to efficiently collect or dissipate thermal energy [4]. Appropriate measurement and inspection methods, based on the infrared thermography, will be described, too [5].
