|Teacher/Coordinator: Prof Warren Julian|
Classes: Lectures and laboratory classes in four day intensive mode (9am-5pm)
Assessment: two assignments (2x25%); two laboratories (2x25%)
|The objective of this unit is to understand the basic photometric and colorimetric terms, quantities and relationships and be able to apply these in practical and theoretical situations.|
This unit introduces the rational system of measurement of lighting qualities and provides the bases for photometric and colorimetric calculations. Topics include: the development of the system of measurement of luminous flux; luminous intensity; illuminance; luminance; reflectance; luminance factor; transmittance; mention of refraction, diffraction and reflection laws; relationships between luminous qualities; basic calculations involved with diffuse surfaces; inverse square law; cosine law; interreflections; Munsell Colour System; CIE Colour System; graphical representation of photometric data; measuring instruments; accuracy; repeatability; colorimetric calculations (chromaticity coordinates Yxy, L*A*B*, Luv, correlated colour temperature, colour rendering indices); the integrating sphere; goniophotometry; distribution photometry. Various measurement and calculation techniques are applied in the laboratory exercises which support the unit.
Upon successful completion of this unit the student will know the basic photometric and colorimetric systems used in Australian and other national and international standards.
Students will discover some of the outcomes through laboratory exercises and will demonstrate them in the assignments and examination.This unit of study is offered in odd numbered years only.
