IlluminationObviously, the amount of luminous flux falling on an object emitting no light of its own is very important from the aspect of observation of that object. We wish to know, therefore, how strongly an object or a surface is illuminated and the natural course is to express the ., or .

The Photometric Measuring-units Systemnceptions and units employed in illuminating engineering would have to be extended in scope to include coloured light, and that, until then, the reader should regard the considerations dealt with as referring to white light only.作者: debouch 時間: 2025-3-24 17:27 作者: 接觸 時間: 2025-3-24 20:38
Measurement of Illuminationas an intermediate stage in ascertaining values of other photometric quantities, in which case it is usually sufficient to know the illumination as a relative value only. In the foregoing sections on the measurement of luminous flux and luminous intensity, examples of this procedure have already been given.作者: Mechanics 時間: 2025-3-25 01:11
