Field Spectrometer for Remote Sensing of Vegetation State

Description

The field spectrometer consists of two blocks – optical and computing. The optical block is a two-cannel spectrometer with high resolution, adjusted to measurements under field conditions. Except for measuring and basic channels the device is equipped with a channel of visualization for supervision of a site which is measured. Results of measurements in a digital form are recorded on a flash card or can be transferred to the computing block for accumulation in a database. The device is supplied with detectors of temperature, irradiance and the GPS-receiver for determining of geographical coordinates of a site where measurements are carried out. All these service data are registered together with a measured spectrum. A developed software WINCHL has two channels for processing of the data transferred from optical block – user's (subsystem USWHL) and for scientific purpose.
