Designed by a professional … WebOct 2, 2014 · The edge is ideally perfectly ‘sharp’, straight and of good contrast. One of the better such targets is a back-lit utility knife edge or razor blade. However in practice it can be the shadow cast by a bridge on a satellite photo or a high quality print of a uniformly black rectangle on uniformly white matte paper.

The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc. This principle can be extended to engineer a grating with a structure such that it will produce any diffraction pattern desired; the hologram on a credit card is an example. Diffraction in the atmosphere by sma… WebCut a piece of the CD cover to ride on the outer set of rails in the camera. This piece becomes the clear back to hold the knife-edge.

WebAn optical test bench configured for star testing can readily be modified to allow for both Ronchi and knife-edge testing. These tests allow the operator to visualize zonal defects in the optical system and serve as direct links between … WebThis note describes a convenient working technique for measuring the minimum size focused spot formed by a lens system. The technique is routinely capable of measurement precision of better than ⅛λ. The theory of knife-edge scanning is presented, and the relationship of the measured spot profile to the actual spot profile is shown to be …
