Methods and arrangements to enhance optical signals within aberrated or scattering samples
An optical system has an illumination optical assembly, a detection optical assembly, a wavefront shaping device, and a controller. The illumination optical assembly focuses interrogating optical radiation to a focal point on or in a sample. The interrogating optical radiation propagates to the focal point along a first optical axis. The detection optical assembly direct optical radiation emanating from the focal point to a detector. The emanating optical radiation propagates from the focal point along a second optical axis. The wavefront shaping device is disposed in an optical path of the interrogating optical radiation or in an optical path of the emanating optical radiation. The controller sets a configuration of the wavefront shaping device to correct for aberration. The first optical axis is at a non-zero angle with respect to the second optical axis.
