2. Based upon the results presented in Fig. 5, we feel that a Laser Fluorosensor may be able to remotely map oil slicks and determine region 5 of high concentration of pollution, such as Calcium Lignosulphonate, from an aircraft flying at an altitude of between 1000 and 2000 ft. with a ground resolution of about 10 ft. The instrument could also be used in hydrologic studies for it could detect the dispersal of dyes, such as Rhodamine BN, down to about 4.5 µgm/litre with a ground resolution of about 20 ft. It is clear from the preliminary results obtained to date that laser induced fluorescence has considerable potential as an environmental probe.
