Abstract

A new spectrophotometer to measure a wide variety of the optical properties of materials, such as unidirectional/bidirectional absolute reflectance and transmittance as a function of (a) wavelength, in the range of 0.3 to 2.0 um with a resolution of 0.005 um, (b) angle of incidence in the range of 3° to 65° with an accuracy of 0.5°,(c)state of polarization, 0°, 45°, and 90° of the incident light, has been designed and developed. It is demonstrated that these optical properties can be measured to an accuracy better than 1%. In addition, this multifunctional instrument is tailored to monitor the relative spectral signatures of living vegetation that has been grown under controlled conditions. These spectral signatures are useful for the effective interpretation of remotely sensed data obtained from aircraft and satellite borne instrumentation.
