WebI have also completed my Diploma in Electronics and Instrumentation. As a Project Assistant, I am currently working on the Design and development of CNT based pressure sensor (for ISRO), the Design and Development of CNT based Optical sensors, and the Development of a Non-invasive Blood Glucose Monitoring Based on pulse Signal … Optical pressure sensors detect a change in pressure through an effect on light. In the simplest case this can be a mechanical system that blocks the light as the pressure increases. In more advanced sensors, the measurement of phase difference allows very accurate measurement of small pressure changes. See more In an intensity-based optical pressure sensor, an increase in pressure will cause the source of light to be progressively blocked. The sensor … See more Fibre-optic pressure sensors can be classified as either extrinsic, where the sensing takes place outside the fibre, or intrinsic, where the fibre itself changes in response to pressure. … See more Because of their freedom from electromagnetic interference, fibre-optic sensors are very useful in harsh environments. One example is the oil and gas industry. Conditions in a well can easily reach 20 kpsi … See more A Fabry-Pérot cavity with two parallel reflecting surfaces can be constructed on the tip of an optical fibre (as shown, left).
