Title:
MEASUREING DEVICE AND METHOD OF MANUFACTURING MEASUREING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/208462
Kind Code:
A1
Abstract:
The present invention reduces the deviation of the relative spectral responsivity of a measuring device from a spectral responsivity function without increasing the manufacturing cost of the measuring device. In a luminance meter, a light beam to be measured is branched by a bundle fiber. Each of the plurality of light beams that are obtained passes through a color filter. The relative spectral responsivity achieved by each of the plurality of color filters is made to approximate a standard relative spectral sensitivity. Each of the plurality of light beams that has passed through a color filter is received by a light receiving sensor. Each of the plurality of light receiving sensors outputs an electrical signal in accordance with the light beam received. A derivation mechanism derives a luminance value corresponding to the spectral distribution of the light beams being measured from the plurality of electrical signals that are obtained.
