CIE 198-SP2:2018 Determination of Measurement Uncertainties in Photometry Supplement 2: Spectral measurements and derivative quantities
This report is a second supplement to CIE 198:2011 Determination of Measurement Uncertainties in Photometry for the determination of measurement uncertainties associated with the values of selected quantities in photometry. It deals with spectral measurements and combinations of measured spectral... more DIS 026/E:2018 CIE System for Metrology of Optical Radiation for ipRGC-Influenced Responses to Light
This Draft International Standard defines spectral sensitivity functions, quantities and metrics to describe radiation for its ability to stimulate each of the five photoreceptor types that can contribute, via the melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs),... more
The objective of this report is to lay the groundwork for developing a recommendation on the measurement of effective intensity of flashing lights used for signalling applications. It recommends a convolutional method that will rest on some defined visual impulse response function to calculate the... more
