Abstract: Interferometric focusing (IF), rather than conventional geometric focusing, of excitation light onto a guide-star that is embedded deeply in tissue, increases its fluorescence intensity. The method can extend the depth of wavefront measurement and improve correction inside of tissues because of its ability to suppress both scattering of diffuse light and aberration of ballistic light. The results showed more than two times improvement in SNR and RMS error of the wavefront measurement. Although only ballistic light in the excitation path is corrected, the intensity after wavefront correction increased by 1.5 times. When applying IF to a two-photon microscope with a near infra-red laser, this method would further extend the measurement depth and achieve high SNR for the wavefront sensor.
