Abstract

A device for detecting fluorescence on the surface of the earth is disclosed. The device includes a laser installed in a vehicle, means for irradiating an essentially linear surface area in front of and transverse to the vehicle, a directing device for directing the spread beam downward to illuminate the earth's surface and means for detecting fluorescence on the illuminated surface. The inventive device permits the rapid and effective exploration of a relatively large area without gaps of the earth's surface for fluorescent substances.
