The NIST Detector-Based Luminous Intensity Scale

The Système International des Unités (SI) base unit for photometry, the candela, has been realized by using absolute detectors rather than absolute sources. This change in method permits luminous intensity calibrations of standard lamps to be carried out with a relative expanded uncertainty (coverage factor k = 2, and thus a 2 standard deviation estimate) of 0.46 %, almost a factor-of-two impro...

Simultaneous Orientation of Brightness, Range and Intensity Images

Within the scope of a common evaluation of brightness, range and intensity images, this article introduces a new area based approach to achieve the simultaneous orientation of multiple data types. The actual innovation is the combined least-squares adjustment, which is an extension of object space image matching with ranges and intensities as additional observations. The complete mathematical m...

Intensity, Brightness and Étendue of an Aperture Lamp

Phosphor molecules are excited by ultraviolet light emitted during the steady electrical discharge of the low-pressure gas inside the lamp, and subsequently de-excite via emission of visible light. Some of this light is absorbed and re-emitted by the phosphor. In this problem, assume that there are no losses in this absorption/re-emission. Compare the intensity, brightness and étendue of the li...

A Preliminary Study of the Reducing Intensity of Luminous Bacteria

The effect of a series of redox indicators and systems has been tested with a suspension of luminous bacteria (B. fischeri) in M/4 phosphate buffer of P(H) = 7.6. The indicators behave as expected from their position in the redox series, the most positive being reduced rapidly even in presence of air and before luminescence of the bacteria disappears, those of intermediate position at the time ...

Quantitative Brightness Analysis of Fluorescence Intensity Fluctuations in E. Coli

The brightness measured by fluorescence fluctuation spectroscopy specifies the average stoichiometry of a labeled protein in a sample. Here we extended brightness analysis, which has been mainly applied in eukaryotic cells, to prokaryotic cells with E. coli serving as a model system. The small size of the E. coli cell introduces unique challenges for applying brightness analysis that are addres...
