PHYSICS OF MEASUREMENT (Geomatic Engineering)
Session
1: 3 UC
Lecturers: Week
1 - 6 Dr Krystyna Wilk, Room 138A
Week 7 - 14 Dr Gail Box, Room 102C
Brief
Description:
This
course is for students of Geomatic Engineering. It aims
to provide students with an introduction to some of the
physical principles used in measuring instruments, and examples
of how they are applied. Topics covered include digital
electronics, analogue to digital conversion, transducers,
waves, remote sensing, geometrical and physical optics and
polarisation.
