Abstract We experimentally generate a spatially squeezed light beam and realize a small?displacement measurement beyond the quantum noise limit with this squeezed light. Moreover, we measure about -2.2±0.2 dB spatial squeezing and reduce the minimum measurable displacement from 1.17 ? to 0.99 ? with the signal-to-noise ratio normalized to 1.
