Characterization and comparison of optical source relative intensity noise and effects in optical coherence tomography
… noise and relative intensity noise (RIN) (excess photon noise) constitute optical noise, RIN is the least understood and often the most significant factor limiting the sensitivity of an optical system. The existing and prevalent theory being used for estimating RIN for various light sources in OCT …
