TRANSCRIPT
Project Objectives/Goals
• Develop a “self-aware” fiber optic mesh that is conscious of its current state (temperature, shape, strain, etc.)
• Display the data on a monitor
Approach
• Use fiber optics as a sensor by inserting a grating within the fiber.
• The grating will reflect back certain waveforms.
• Sense the waveform information and use it to reveal the condition of the mesh.
Implementation
• Optics:– Beam-splitter– Fiber Bragg grating– Photodiode
• FPGA:– Compare the voltage reading to the “base state”
