Jessica Gehlhar, Vision Solutions Engineer at Edmund Optics, presents the “Introduction to Optics for Embedded Vision” tutorial at the May 2017 Embedded Vision Summit.

This talk provides an introduction to optics for embedded vision system and algorithm developers. Gehlhar begins by presenting fundamental imaging lens specifications and quality metrics. She explains key parameters and concepts such as field of view, f number, working f number, NA (numerical aperture), focal length, working distance, depth of field, depth of focus, resolution, MTF (modulation transfer function), distortion, keystoning, and telecentricity and their relationships. Optical design basics and trade-offs introduced include design types, aberrations, aspheres, pointing accuracy, sensor matching, color and protective coatings, filters, temperature and environmental considerations, and their relation to sensor artifacts.

She also explores manufacturing considerations, including testing the optical components and imaging lenses in a product, and the industrial optics used for a wide range of manufacturing tests. Depending on requirements, a wide variety of tests and calibrations may be performed. These tests and calibrations become important with designs that include technologies such as multi-camera, 3D, color and NIR (near-infrared).

Here you’ll find a wealth of practical technical insights and expert advice to help you bring AI and visual intelligence into your products without flying blind.
