How to measure flatness with optical flats

WebFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes. WebThere are a number of ways to measure the flatness of a surface. The most common method within the Flat Lapping sector is by using a …

http://starrett-webber.com/Fringe.html WebFlatness is often described as being “the 2D version of straightness”. A straightness requirement applies to a 1D (linear) surface trace or axis in 3D space, whereas a flatness requirement applies to a 2D (planar) surface in 3D space. A flatness measurement can be approximated by a series of straightness line-measurements but note that the ...
