Laser diode self-mixing: Range-finding and sub-micron vibration measurement (2018x13)

Data de estreia: Dez 09, 2018

A plain laser diode can easily measure sub-micron vibrations from centimeters away by self-mixing interferometry! I also show how this technique can be used for range-finding. http://sci-hub.tw/http://iopscience.iop.org/article/10.1088/1464-4258/4/6/371/pdf https://www.jameco.com/Jameco/Products/ProdDS/2120428.pdf https://www.spiedigitallibrary.org/journals/optical-engineering/volume-57/issue-05/051506/Overview-of-self-mixing-interferometer-applications-to-mechanical-engineering/10.1117/1.OE.57.5.051506.full?SSO=1 Nerd Thunder!
