| 主权项 | 1. Goniochromatic measurement method for the determination of the luminance of particles having a particle size of 0.1-500 μm, comprising: incorporating the particles into a transparent medium and applying the medium with the particles to a dark support or applying the particles in powder form to a dark support; and then illuminating the particles on the support from a fixed angle relative to the plane of the support, and measuring the back-scattered light at multiple different angles along a semicircle extending above the plane of the dark support. | ||
