An intensity modulated extrinsic fiber optic Refractive index sensor is presented. A ‘Y’ shaped bundle fiber and mirror are used. Sensor principle is based on change in angle of reflected light caused by refractive index change of the medium surrounding the bundle fiber. The experimental results obtained for liquid of different refractive indices prove the sensor potential to act as sensitive refractometer..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
