      In addition, an illuminance meter is set in the lighting equipment for monitoring the variation of light conditions. The luminance is measured at every one second by luminance meters (Konica Minolta, LS- ). We set the luminance meters below the compartment, and measure the focus points on the smoke layer surface by a degree tilted mirror.

    Luminance is the measure of the amount of light reflected or emitted from a surface. It is typically expressed in cd/m². Luminance levels can be measured with a luminance meter, shown in Figure , or through the use of high dynamic range (HDR) imaging techniques together with a digital camera and luminance mapping software (e.g. Photolux), example shown in Figure Luminance levels can b. Compact, fast industrial light meter High-speed robust Luminance, Illuminance & Flicker meter. Admesy’s Asteria is a high-speed measurement device suited for luminance, illuminance and flicker measurements. Based on the popular Admesy platform the Asteria is designed for in-line use with integrated calculating power for easy implementation.

      The Gossen GO Light Meter features an integrated contrast measurement system. Offers the ability to detect if the contrast can be managed by the camera sensor or film. Includes both incident and reflected light metering methods. Displays the exposure value in 1/3 increments. Includes a timer for exposures from 1 second up to 30 minutes. 5 Properties of Illuminance Meters and Luminance Meters 6 Acronyms Annex A (normative) - Sources and Filters Used for MEASURING METHODS OF LED LIGHT BARS USED IN LCD BLUS: IEC 1ED DISPLAY LIGHTING UNIT - PART ELECTRO-OPTICAL MEASURING METHODS FOR LED FRONTLIGHT UNIT Standards Referencing This Book - (Show below.
