Precision Enhancement with Bright Kerr Amplitude-Squeezed Light for Static-Loss Microscopy

For absorption imaging, optical noise is a limitation [1]. Photon counting experiments using correlated photon pair sources can achieve sub-shot noise imaging but are not scalable to high brightness [2]. While lowering the noise floor increases the signal-to-noise ratio without increasing the signal's power, enhancing the precision reduces the variance of estimates. In imaging, improved precision can lead to higher contrast images, allowing regions with similar values to be more easily distinguished due to smaller error bars [2].
