Straightness Testing
Straightness Testing
(OP)
Hi
I'm having real difficulties trying to find out information about straightness testing in metrology. The problem lies around having to find different methods (apart from gauges) used to measure errors in straightness, and the components that these methods are used to measure.
I'd be really gratefull for any usefull links or advice.
Cheers

Geomatics / theodolites, levels etc can be used if accuracy is to be of the order of mm or larger say on land, concrete slabs, alignment of rollers etc
Photogrammetry can be used in metrology appilcations eg surfaces car panels, aeroplane parts, propellers etc
Some very specialised Laser Theodolites have been made to do this from 1/50000 to 1/200000 accuracies
