Abstract:
     A set of standard achromatic boards with different grey scale values is suitable for the 0.4-1.2 micron spectral band. The coefficient of reflection for the white board is 90-95%, and that of the black one is 3-3.3%. The neutral and cosine characteristics of the sprecrtum are fairly good. It has a microfoam textile texture type of coating, which is mat, water-proof, aging-resistant and durable. Its principal applications are for astronautic and aeronautic remote sensing, ground object spectral measurement, photometric chromatography, photography etc. as reference datum. It can either be used indoor or in field surveying as a reference standard board.
