Introduction to the design and optical layout of an open source laser interferometer for measruing lengths in the nanometer regime over large distances of up to 1 meter.
The project aims to be accessible avoiding costly components and complex machined parts.
(Note: There is a small error in the picture of the 'Michelson Interferometer with Offset' - the detector is drawn on the wrong side.)
