This section provides public BTF and BRDF (database and dense datasets) measurements measured by the state-of-the-art gonioreflectometric device at Institute of Information Theory and Automation (UTIA), The Academy of Sciences of the Czech Republic.

The current setup allows for HDR measurements of arbitrary angular resolution, spatial resolution 25µm/pixel (approx. 1000 DPI), and spectral range 420-700 nm. A typical angular accuracy is 0.03° and sample size up to 140 x 140 mm.
