Noncontact true temperature measurement, 2

A laser pyrometer was developed for acquiring the true temperature of a levitated sample. The reflectivity is measured by first expanding the laser beam to cover the entire cross-sectional surface of the diffuse target. The reflectivity calibration of this system is determined from the surface emissivity of a target with a blackbody cavity. The emissivity of the real target can then be calculated. The overall system constant is obtained by passively measuring the radiance of the blackbody cavity (emissivity = 1.0) at a known, arbitrary temperature. Since the photosensor used is highly linear over the entire operating temperature range, the true temperature of the target can then be computed. The latest results available from this on-going research indicate that true temperatures thus obtained are in very good quantitative agreement with thermocouple measured temperatures

Understanding sustainability through the lens of ecocentric radical-re?exivity : implications for management education

This paper seeks to contribute to the debate around sustainability by proposing the need for an ecocentric stance to sustainability that reflexively embeds humans in—rather than detached from—nature. We argue that this requires a different way of thinking about our relationship with our world, necessitating a (re)engagement with the sociomaterial world in which we live. We develop the notion of ecocentrism by drawing on insights from sociomateriality studies, and show how radical-reflexivity enables us to appreciate our embeddedness and responsibility for sustainability by bringing attention to the interrelationship between values, actions and our social and material world. We examine the implications of an ecocentric radically reflexive approach to sustainability for management education

Noncontact temperature pattern measuring device

Laser pyrometer techniques are utilized to accurately image a true temperature distribution on a given target without touching the target and without knowing the localized emissivity of the target. The pyrometer utilizes a very high definition laser beam and photodetector, both having a very narrow focus. The pyrometer is mounted in a mechanism designed to permit the pyrometer to be aimed and focused at precise localized points on the target surface. The pyrometer is swept over the surface area to be imaged, temperature measurements being taken at each point of focus
