Open Source Laser Interferometer - Part 1: The Optical Design.

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.)
