I. Schneider et al., FIBEROPTIC NEAR-INFRARED REFLECTANCE SENSOR FOR DETECTION OF ORGANICSIN SOILS, IEEE photonics technology letters, 7(1), 1995, pp. 87-89
A near infrared fiber-optic chemical sensor system using reflectance s
pectroscopic measurements has been assembled. This system was evaluate
d and found attractive for remote detection of organics in soils over
distances of at least 30 meters.
