Abstract

Low coherence interferometry (LCI) is a noninvasive sensing method that provides depth information with high resolution and high sensitivity When the coherence of broadband incoherent light is modified by the same spectral modulation technique utilized in femtosecond pulse shaping¹, one can achieve more functional sensing. In this paper, coherent function synthesis by manipulating the spectral phase of low coherence light in the frequency domain and its application in a reflectometry are described.
