Telecentric Optics for Focus Analysis
Magnification variations due to changes in focus setting pose problems for vision techniques, such as, depth from focus and defocus. The magnification of a conventional lens can be made invariant to defocus by simply adding an aperture at an analytically derived location. The resulting optical configuration is called “telecentric.” It is shown that most commercially available lenses can be turn...
متن کاملTelecentric Optics for Computational Vision
An optical approach to constant-magniication imaging is described. Magniication variations due to changes in focus setting pose problems for pertinent vision techniques, such as, depth from defocus. It is shown that magniication of a conventional lens can be made invariant to defocus by simply adding an aperture at an analytically derived location. The resulting optical connguration is called \...
متن کاملOptical measurement techniques with telecentric lenses
This course on optical 2d-measurement technique has been created during the development of the telecentric lenses from Schneider-Kreuznach. First of all we had the idea to explain to the "non optics expert" the differencies between normal lenses and telecentric optical systems by introducing the laws of perspective (Chapter 2). But in the course of writing it became very soon evident that we ha...
متن کاملMeasurement and Correction of Accelerator Optics
This report reviews procedures and techniques for measuring, correcting and controlling various optics parameters of an accelerator, including the betatron tune, beta function, betatron coupling, dispersion, chromaticity, momentum compaction factor, and beam orbit. The techniques described are not only indispensable for the basic set-up of an accelerator, but in addition the same methods can be...
متن کاملMultiple-imputation for measurement-error correction.
BACKGROUND There are many methods for measurement-error correction. These methods remain rarely used despite the ubiquity of measurement error. METHODS Treating measurement error as a missing-data problem, the authors show how multiple-imputation for measurement-error (MIME) correction can be done using SAS software and evaluate the approach with a simulation experiment. RESULTS Based on hy...
