Profile Summary

Keith B. Doyle has over 30-years of experience in the field of optomechanical engineering and the development of high performance optical systems including ground, aerial and space-borne sensors for aerospace, astronomical, and commercial applications. Keith is considered an expert in the field where he has developed novel integrated analysis techniques to optimize system architectures and enable the development of cutting-edge optical system technology. He was named an SPIE Fellow in 2014 and was the recipient of the 2015 SPIE Technology Achievement award.

Keith is currently an Assistant Head of the Engineering Division at MIT Lincoln Laboratory. The Division works in partnership with all the other Laboratory technical divisions to design and build advanced technology systems of national importance. Projects include space and aircraft payloads and ground-based systems.

Prior to joining MIT/Lincoln Laboratory, Keith was a Vice-President of Sigmadyne, Inc. where he provided optomechanical consulting services and supported the development of the commercial software product, SigFit, which is used in four continents across the globe. Prior to joining Sigmadyne, Keith worked as a Senior Systems Engineer at Optical Research Associates as part of their engineering consulting team.

Keith enjoys sharing his work and advancing the field of optomechanical engineering through teaching, publishing, and mentoring. This includes active participation in SPIE symposia authoring technical papers, teaching short courses, and writing books. The second edition of Integrated Optomechanical Analysis was completed in 2012. He completed his Ph.D. in Engineering Mechanics with a minor in Optical Sciences at the University of Arizona in 1993.

Course Instructor
SC1120: Finite Element Analysis of Optics
This course presents the use of finite element methods to model and predict the behavior of optical elements and support structures including lenses, mirrors, windows, and optical mounts in the presence of mechanical and environmental loads. Students will learn general FEA modeling strategies and guidelines specific to optical systems including how to develop low-fidelity models to quickly perform optomechanical design tradeoffs as well as the creation of high-fidelity models to support detailed design. Emphasized will be the application of FEA techniques to meet optical system error budget allocations including mounting tolerances, alignment errors, optical surface distortions, image stability, and wavefront error. In addition, use of FEA to ensure structural integrity requirements including yield, buckling, and fracture will be discussed.
SC254: Integrated Opto-Mechanical Analysis
This course presents optomechanical analysis methods to optimize the performance of imaging systems subject to environmental influences. Emphasized is the application of finite element techniques to develop efficient and practical models for optical elements and support structures from early design concepts to final production models. Students will learn how to design, analyze, and predict performance of optical systems subject to the influence of gravity, pressure, stress, harmonic, random, transient, and thermal loading. The integration of optical element thermal and structural response quantities into optical design software including ZEMAX and CODEV is presented that allow optical performance metrics such as wavefront error to be computed as a function of the environment and mechanical design variables. Advanced techniques including the modeling of adaptive optics and design optimization are also discussed. Examples will be drawn from ground-based, airborne, and spaceborne optical systems.
