Claim Text:
1. A system for collecting information from a wellbore, the system comprising: a surface controller operable to control the operating parameters of the drill string, the drill string having a drilling tool and a drilling optimization collar proximate the drilling tool, the drilling optimization collar having a collar sensor, a control unit, a power source, and a light source, wherein: the collar sensor comprises a sensor filament, the control unit is communicatively coupled to the sensor filament and the surface controller, the light source is optically coupled to the sensor filament, the power source is electrically coupled to the control unit and the light source, the sensor filament is disposed about the periphery of the drilling optimization collar, and wherein a refractive index of the sensor filament is configured to change when one or more of a wellbore condition changes, and the control unit comprises a light sensor to measure the refractive index of the sensor filament and to detect changes in the refractive index of the sensor filament.
