<p>A microscope for optical imaging of high optical scattering coefficient biological tissue, comprising an optical excitation source for irradiating a scan area of the sample and generating optical emissions, wherein the sample has a first face facing away from the source and a second face facing the source. A two dimensional element for scanning the light over the sample; a focusing element having a numerical aperture NAi to focus the light onto the sample; a first optical condenser to collect light from the first face, the collected light comprising source transmitted light and first optical emission generated in the sample, the condenser having a NA2 larger than NAi; an optical filter to block the transmitted source light; an aperture with a size corresponding to the irradiated area of the sample, the aperture at the conjugate image position of the sample generated by the condenser; and an optical detector collecting light from the first face for detecting the first optical emission from the scan area.</p> |
