ABSTRACT:
In order to achieve airborne exploration for minerals in which both color and size information is obtained from fluorescing targets, a pulsed ultraviolet source is directed downwardly from the aircraft to a target area, and light from any responsively fluorescing discrete target is passed through receiving optics which includes a plurality of choppers of different fineness. A multiply-chopped signal is passed through a light pipe which includes filters to separate the signal into a plurality of electronic channels according to the respective color components. Signals are further processed by division into a plurality of parallel paths according to chopper frequency and applied to a series of integrators which are specially configured to remove noise from several sources to markedly improve the signal to noise ratio. The data thus obtained is stored, along with time and position information, onto conventional digital recording means for subsequent retrieval and analysis. In a preferred embodiment, a pulsed ultraviolet light source is employed which continuously illuminates a large width, narrow depth target area in conjunction with an array of light pipes in the receiving optics of which each light pipe in the array monitors only a portion of the illuminated target area. Alternatively, a scanning ultraviolet source may be employed.
