摘要：

A portable dual-channel instrument for rapid optical spectral reflectance measurements is described. Twenty discrete wavelengths spanning the range from 365 to 690 nm are scanned using an interference wedge filter. Seven more infrared wavelengths from 700 to 1000 nm are obtained with discrete interference filters. The 27 fully digitised values of the ratio measurements obtained in 3 s from this instrument are recorded on cassettes for data processing.
