Abstract
We report on the study of an infrared adaptive interferometer [1]. The originality comes from the use of a liquid crystal light valve (LCLV) as the nonlinear medium. Due to self-diffraction, an adaptive holographic interferometer always keeps a linear detection without requiring feedback electronics. The characteristic response time of the LCLV leads to suppress unwanted low frequency phase variations coming from instabilities and environment fluctuations. Moreover, it allows to consider new applications using complex fields, such as speckle patterns.
