The dataset contains angle dependent spectral reflectance measurements of materials in the infrared spectrum at a wavelength of 945 nm taken by a time-of-flight camera for an angle range of 0° to 80° in incremental steps of 10°, mounted on an adjustable angle measurement device. Each data file is structured in columns with two parameters: reflectance (%) and incidence angle (°). For each single material measurement a description file is attached in a separate ZIP-file. The extended dataset include new materials such as vehicle varnish and moss rubber. This new version further includes pictures for almost each of the measurements to depict the measurement setup and environmental conditions during the data acquisition. They are provided in a separate ZIP-file. Note: Please always use the latest version!
