The impetus for the current research and development towards the realization of a remote monitoring, non-intrusive sensing system for real time monitoring of the environment, stems from the many challenges and constraints faced by the civilian and defence users of conventional technologies. The focus of the current work is on adopting innovative approaches in the design and development of a photonics based system for real time determination of the free air stream velocity, with higher degree of sensitivity and accuracy. Thephotonicssystem can be suitably modified for applicationsonboard automobiles, aircrafts and underwater platforms. © Research India Publications.
