Abstract

To develop a simple technique for imaging hidden objects embedded in or behind a scattering medium is challenging and important for many applications (e.g. biomedicine).¹ One of the promising techniques developed is to use short-pulse Raman gating² in hydrogen for detection of unscattered photons, which carry the least degraded image information. For practical purposes however, Raman imaging with compact solid-state Raman shifters has obvious advantages compared with a H₂ shifter used so far.
