We have built a simple, undersea radiometer that measures ten integral moments of the radiance as functions of depth in natural waters. From these data it is possible to calculate nine spherical moments of the scattering function, provided that this function varies slowly in the horizontal planes (i.e., the water is fairly stratified).

Review of Scientific Instruments, 1950
Total radiated heat loss and average surface temperature of living bodies have heretofore required laborious computation from numerous local measurements. The present study introduces the blackbody principle for this objective. Shieldless surface receivers have been designed, and built from identical and symmetrical sets of thermoelectric foil ...

Radiometer equation for noise comparison radiometers
IEEE Transactions on Instrumentation and Measurement, 1995A complete radiometer equation is derived and used to develop better corrections and uncertainty estimates. I believe it to be the first thorough analysis of radiometers with unisolated front ends. We show that a corrected unisolated radiometer can have an accuracy similar to that of a well-isolated radiometer. The radiometer error is insignificant for

Applied Optics, 1973
The active cavity radiometer (ACR) is a pyrheliometer that accurately defines the absolute radiation scale. The physics of the pyrheliometric method and the ACR approach to this method are presented in detail. A mathematical abstraction of the method is generated through a quasi-equilibrium analysis of the power balance of the ACR's cavity detector. An

The Physics Teacher, 2002
The author has a radiometer that is about 80 years old that he uses in demonstrations for various audiences. When exposed to light, the “fan” turns very fast, then slows down, and eventually comes to rest. But when I touch the glass with my hand, the whirling starts again. Sometimes, before restarting, the fan turns in the opposite direction for awhile.
