The light intensity (respectively light flux) is calculated directly from the dimensions of the instrument by the aid of the equation of state of gases and the Stefan-Boltzmann fourth-power law of radiation. Thus it needs no calibration by the aid of other instruments. The instrument is ...
Method for colorimetric determination of light intensity comprises irradiating the reduced form of a redox dye to convert it to the oxidised form which serves as the signal of the measurement value. A reducing agent, esp. ascorbic acid, is added to convert the oxidised form back to the colour...

The intensity of each main colour in the illuminating light is measured by dedicated LEDs having corresponding colour measurement bands. The measurement of individual intensities is used in adjusting the proportional strengths of corresponding signals originating from the camera's detector, for example a...

The acoustic pressure in the focal zone of the ALLFU field and the transducer-transmitting voltage response were quantitatively determined by measuring the diffraction light fringe intensity. The results show that the brightness of the Schlieren image is a linear function of the acoustic intensity ...
