Most attention is paid to color and luminous density measurement , with color difference as a plus
2.
The interface of the sofyware is menu - styled . the components that deal with color and luminous density measurement , including standard input , system calibration , are emphasized
3.
The second chapter briefs the fundamental principles and methods of photometric and colorimetric measurement , including the measurement principia of luminous density , luminous flux , luminance and chrominance
4.
Photometric and colorimetric measurement , such as luminous flux measurement of all kinds of lamps , luminous density measurement in classrooms and color measure of color tv etc . are commonly used in daily manufacturing . at present , special photometric and colorimetric instruments are available
