One of the most important thing to solve the environmental pollution problems are to establish a measurement technique to detect the kind and the type of pollution timely, quantitatively and qualitatively with accuracy and precision. The conventional measurement techniques such as wet analysis methods and spectrophotometric methods are generally time-consuming and require many man-powers, so it is apt to induce relatively higher errors in analytical processes. The application of laser for environmental remote sensing is the most powerful candidate to overcome the above-mentioned drawbacks of the conventional methods. In this report, we propose the possibility of laser application for environmental sensing. (Author).
