An optical correlation setup is used to image transparent objects through scattering media, and 10-μm longitudinal and 2.5-μm transverse resolution are achieved. Spectral-bandwidth sampling of the light source is made possible by a tunable dye laser and leads to signal enhancement as a result of sampling interferogram filtering. An optical system allows observation of sample slices without the need for a translation stage.
