This page will give a brief overview of the current range of systems that have been developed at the University of Lethbridge. These systems are state-of-the-art and some of the best systmes of their kind in the world. We continue to develop new systems and ideas for the sampling of a surface BRDF.
This was the first prototype instrument. Full manual control - slow but it works and is useful.
Arc raduis = 60 cm
Instrument = ASD Fieldspec 3 FR
The latest develoment for the manual instrument - constructed in aluminum with 10 degree angular resolution.
Arc raduis = 120 cm
Instrument = ASD Fieldspec 3 FR
The first automatic instrument. Stepper motor controlled, quarter arc design, mast, real-time reflectance computation. Built in collaboration with Dr. Scott Noble - University of Saskatchewan.
Arc raduis = 200 cm
Instrument = Ocean Optics USB 4000 (2)
A heavy payload quarter arc system developed for use with imaging spectroradiometers.
Arc raduis = 200 cm
Instrument = Specium ImSpector V10E
The most recent quarter arc design - built to accomodate the Spectral Vista HR-1024
Arc raduis = 160 cm
Instrument = Spectral Vista HR-1024
