Q: What makes TDLS so exciting? A:The world is NOT in the labIn much of engineering, measurements need to be made not under lab conditions but in the field. Measurement techniques that work well in the lab under controlled conditions are often poorly suited to such conditions. Photonic sensors are capable of sensing physical and chemical changes in inaccessible locations and under very harsh operating conditions. Many of these applications have to deal with high temperatures (800-900 Celcius), high pressure (several bars) and toxic environments. This often makes photonic sensors the only viable option. The field of industrial sensing has undergone huge transformations as regards the potency and versatility of sensing technologies that are currently used. TDLS has emerged as the one of the front-runners in diverse fields such as industrial process control, oil and gas prospecting, environment monitoring, detection of hazardous chemicals, space explorations, clinical breath analysis, study of microbes, agriculture and basic sciences.
