Well characterised sources of thermal radiation are essential for photometry, radiometry, and
thermometry. They serve as reference radiators for the calibration of detectors and radiance …

A task group of CCT-WG5 (radiation thermometry) was established in May 2008 to write text
for the mise-en-pratique for the definition of the kelvin (MeP-K) for high temperatures. This …

Radiometry based on black bodies remains one of the fundamental fields of radiometry.
Black bodies are widely used as standard sources in radiometry of noncoherent optical …

Abstract At the Physikalisch-Technische Bundesanstalt (PTB) silicon diode-based narrow-
band interference filter radiometers (FR) are used for the radiometric determination of …

The “Mise en pratique for the definition of the kelvin”(MeP-K) as a guide for the realization of
the kelvin is presently revised to incorporate the temperature scales in current use as the …

While absolute detectors are routinely used to maintain fundamental units and scales in
radiometry and photometry, well-characterized sources have an irreplaceable niche in their …

A CCD camera, which has been specially equipped with narrow-band interference filters in
the visible spectral range for temperature measurements above 1200 K, was characterized …

The measurement uncertainty of illuminance and, consequently, luminous flux and luminous
efficacy of LED lamps can be reduced with a recently introduced method based on the …

The luminous intensity unit of candela was realized based on filter-radiometer, which is
traceable to detector-based primary standard electrical substitution cryogenic radiometer …

During the past decades increasing use of machine vision in dimensional measurements
has been seen. From a metrological view every serious measurement should be traceable …
