About Edward Dehoog

Optical Engineering & Analysis www.opticalea.comI like challenging projects that require outside the box solutions and thinking deeply about the trade offs for each approach to the solution. To quote a former colleague, "Never say it's impossible. Ask lots of questions trade off and alternative solutions to the core problem. Erase no bid from your vocabularylI am an experienced optical engineer capable of bringing concepts into reality with extensive experience in the following areas: Optical Instrumentation & Lens Design: Lithography, Camera Lenses, Microscope Objectives, Zoom Lenses, Adaptive Optics, Scanning Systems, 3D Displays, Panoramic Optics, Polarimeters, Spectrometers, Head Mounted Displays, LIDARMilitary & Space Optics: Thermal Imaging Systems, LWIR / MWIR Optics, Telescopes, Off Axis Un-obscured Mirror Systems, Adaptive Optics, Zoom Lenses, Head Mounted / Heads Up Displays, Night VisionBiomedical Optics: Optical, Confocal & Fluorescence Microscopes, Optical Coherence Tomography (OCT), Tissue Optics Visual and Ophthalmic Optics: Eye Safety Calculations, Visual Acuity / Performance Modeling, Intra Ocular Lenses (IOL), Scanning Laser Ophthalmoscopes (SLO), Retinal and Corneal OCT, Wavefront Sensors (WFS), Corneal Topography & BiometryNon-Imaging and Illumination Optical Design: Fresnel Lenses, TIR Lenses, Solar Concentrators and Light Distribution Shaping Optics Stray Light Analysis: Impact of Scatter & Ghost Reflections on Image Quality, Impact of Diffractive Optical Elements on Stray Light and Image Quality, Mitigation StrategiesDesign for Manufacture: Tolerancing, Assembly & Alignment of Optical Systems, Optical Test Planning and DevelopmentOptical Testing: Image Quality Analysis, Interferometry, Wavefront Sensing & MTF TestingRadiometry: Optical System Power Budget Calculations, Visible/IR Target Detection Systems, Optical Detectors, FPAs and Cameras Computer Skills: Zemax, Fred, Code V, Matlab, Excel, Word & PowerPointScientific Programming for Optical Simulation: User Defined Features, Analysis and Macros in Zemax & FRED, Surface Fitting, Data Analysis, Image Quality Analysis and Optical Simulations in MATLABContact me at oea.dehoog@gmail.com to a see my project portfolio.

    Extension Instructor - Optical Engineering & Instrument Design
    Uc Irvine Nov 2018 - Jun 2020
    Irvine, Ca, Us
    Instructor for Geometrical and Physical Optics. Developed curriculum and problem sets to help student bridge the gap between the text book and work bench. Instead of problems like so:Find the image distance for an object at 100mm in front of a 10mm focal length lens?This is your basic a physics textbook problem, that is highly unlikely to be seen in optical engineer. This does not require the student apply any engineering principles Simple plug numbers into an equation and get and an answer. My goal was to find problems I encountered on a regular basis as an optical engineer. Instead of textbook problems, I gave problems that forced students to think about how knowledge of optics is applied to a real engineering application. For example:I want to image my cat Wally onto a 1/3" cmos sensor in a c mount package. I want to image all of Wally but he bites so I need to have a working distance of a least 1 meter. Find a stock lens that allows all of Wally to be seen by the sensor. If I want to resolve Wally's whiskers. What pixel size and F# are required assuming perfect imaging. ( You need to look up the dimension of a 1/3" cmos and working distance of c mount ).
