Self-mixing interferometry (SMI) based on nanometer fringes and polarization flipping is realized. The in- terferometer comprises a single-mode He-Ne laser and a high-amplitude reflectivity feedback nfirror. The nan...
Noise reduction is one of the most exciting problems in electronic speckle pattern interferometry. We present a homomorphic partial differential equation filtering method for interferometry fringe patterns. The diffus...
