How this equipment actually works
Written for the person who has to specify it, not for a brochure. No form, no email address, no download. If a supplier will not answer one of the questions in these guides in writing, that is worth knowing before you order.
Triangulation, field width, X interval, and the scan rate question nobody answers
How do I cross reference a motor?NEMA against IEC frames, 50 Hz against 60 Hz, duty cycles and efficiency classes
What frame rate do I need?Why the headline fps figure is almost never the one you get
What is digital image correlation?Speckle patterns, 2D against stereo, and where DIC beats a strain gauge
How do I specify a shaker?Sine against random against shock force, stroke, payload and standards
