P 09701—Corning Tropel Light. Gage™ Metrology System Background: “Corning’s Light. Gage™ system is an advanced, full surface interferometer for measuring flatness, parallelism and depth” 2 mjb 8482@rit. edu

P 09701—Corning Tropel Light. Gage™ Metrology System P 09701 In other words: (Tunable Laser) + (Infrared Camera) = + (Math Algorithms) 3 mjb 8482@rit. edu

P 09701—Corning Tropel Light. Gage™ Metrology System P 09701 The Problem: The 1 st generation Light. Gage™ only measures one side of a part… (Corning is also looking to measure both …Corning Tropel wants itfor engineers to hire) sides… THEY GAVE IT TO US SO …but their engineers couldn’t figure out how to do it! 4 mjb 8482@rit. edu

P 09701—Corning Tropel Light. Gage™ Metrology System Our Task: Design, build and test a working prototype of the 2 nd generation Light. Gage™ system. Master System Controller Sensor Controller (PC) Source Unit Sensor Parts Handling 5 mjb 8482@rit. edu

P 09701—Corning Tropel Light. Gage™ Metrology System Looks easy, doesn’t it? - Complete vibration isolation - Isolation from ambient temperature changes -Remember, automated, motorized Completely Corning engineers couldn’t -make itmust move to within < 1 mm of top Sensor work. surface of part, every time - Must accurately measure part in under a minute - Anybody can use it 6 mjb 8482@rit. edu

P 09701—Corning Tropel Light. Gage™ Metrology System Looking for engineers interested in: - Photonics/optics - Electronics, systems integration - Data acquisition, programming - Thermal analysis - Ergonomics, user interfacing - Mechanical design - Laser! interferometry - Getting a job 7 mjb 8482@rit. edu
