A New Instrument for Comprehensive Study of Infrared Remote Sensing of Physiological Properties of Vegetation Covers
Abstract
An instrument to remotely study the physiological properties of vegetation canopy has been designed and developed. The radiometer is a passive microcontroller-based optoelectonics system, using series of multi-feedback band pass electronics circuits coupled to a 200 by 24 refracting system. The output is taken via an eight-readout 16 by 4 display console: 1. Reflectance RF1(at 430-450nm); 2. RF2 Greenness index(at 510-530nm); 3. RF3( at 730-780nm); 4. RF4 ( at 630-650nm); 5. Fluorescence FL( at 660-680nm); 6. Chlorophyll Luminiscence CLM: 7. Vegetation Moisture VM and 8. Canopy Temperature VT. The radiometer has beeen radiant calibrated. The radiometer was tested and used to observe some stress-mediated physiological properties in vegetation canopy.Reults confirmed predictions in the literature.
