  • Patent number: 9019504
    Abstract: A transportable goniospectrometer with a constant observation center for a radiometric measurement of the reflection of a natural surface includes a spectrometer having an optical unit and a sensor. A main pillar has a lower and an upper pillar end. An arc has a fixed and a free arc end. A slide is disposed displaceably and fixably along the arc. The slide carries the optical unit orientated towards the observation center. A cantilever has a fixed cantilever end connected to the upper pillar end via a screw connection, and a free cantilever end which has a suspension that is rotatable and fixable about a vertical axis. The suspension is connected to the sensor and to the fixed arc end of the arc. The suspension is configured to position the arc at a distance of the arc radius of the arc above the natural surface.
