OptiFlex Asad Chaudhry Guthrey Coy Brandonn Gorman 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. Block Diagram Optical Laser Photodiode Processing I/O Beam-splitters FPGA FBG cable Monitor Implementation • Optics: – Beam-splitter – Fiber Bragg grating – Photodiode • FPGA: – Compare the voltage reading to the “base state” Division of Labor Task Asad Guthrey Optics assembly Brandonn x FPGA Interfacing x Programming x x x Algorithm Design x Documentation x x x Testing x x x Schedule Components/Budget Product FBG cable Quantity Unit Cost Cost 36 $39 $1,404 1 $150 $150 single mode fiber coupler 36 $100 $3,600 photo diode 36 $50 $1,800 1 $199 $199 "laser" Altera Cyclone II FPGA Dev Kit misc. n/a $500 Total Cost $7,653 Risks and contingency plan • • • • • • • Malfunctioning components Exceed budget FPGA time constraints Having enough input ports to work with Breakable expensive fiber optic cables Longer assembly/testing time than expected The accuracy of the data we will gather Extensions • Use a 3D modeling software to represent the shape of the mesh on a computer Any Questions?
