Description

Optical Sensors. Instructor: Prof. Sachin Kumar Srivastava, Department of Physics, IIT Roorkee.

This course provides detailed insight of the field of optical biosensors and their basic working principles. Starting with the introduction of basic components, characteristics, performance parameters and fabrication techniques , this course brings the learner to the mesmerizing field of sensors based on basic principles of optics. The basic optical phenomena/characteristics and their sensing applications have been discussed in detail. The optical properties of tissues and optics in the biomaterials has been discussed providing some further insights into optical biosensing applications. The course also ends with notes on terahertz sensing applications and future directions of research. (from nptel.ac.in)
