摘要
Self-adaptive interferometry allows the measurement of small optical phase modulations in noisy environments and with strongly distorted optical wavefronts. We review two techniques of self-adaptive interferometers based on liquid crystals spatial light modulators, one obtained by using an optically addressed light valve, the second one realized by adopting a digital holography CMOS-LCOS scheme. The adaptive character of these two types of holographic interferometers will be analyzed and compared.
