The design and calibration of a new hyperspectral Compact Laboratory Spectro-Goniometer (CLabSpeG) is presented. CLabSpeG effectively measures the bidirectionalreflectance Factor (BRF) of a sample, using a halogen light source and an AnalyticalSpectral Devices (ASD) spectroradiometer. The apparatus collects 4356 reflectance datareadings covering the… (More)
Figure 6. Bidirectional Reflectance Factor of a Fagus sylvatica L. leaf at 550 nm (A), 850 nm (B) and 1650 nm (C), for light source position set at 0° azimuth and 30° zenith (left) and at 0° azimuth and 60° zenith (right). The sensor is azimuthally positioned all over the hemisphere and ranges in zenith between 0° and 60°, with 15° increments. Sensor’s positions are marked by dots, while incident direction is presented by a star. The bar scale indicate reflectance values.
