Abstract
The present invention relates to a method for imaging a target object within media which bring about simultaneously scattering and aberration capable of imaging of deep depth and high resolution not only by maximizing an accumulation of a single aberration but also by noticeably reducing an distortion of image using simultaneous correction of the scattering and the aberration.

A method for imaging a target object within media which bring about simultaneously scattering and aberration comprising the following steps:
- (a) obtaining a plurality of emission beams emitted from the target object in accordance with change of an incidence angle of an incidence beam;
- (b) constructing a time-resolved emission matrix which is composed of an incidence wave vector of the incidence beam and an emission wave vector of the emission beam;
- (c) re-constructing the time-resolved emission matrix to an incidence path aberration correction matrix which is composed of the incidence wave vector and a deviation between the emission wave vector and the incidence wave vector;
- (d) applying an incidence path aberration correction set to the incidence path aberration correction matrix, thereby calculating an optimum incidence path aberration correction set at which a total intensity of complex sum of a deviation spectrum between the emission beam and the incidence beam is maximized;
- (e) correcting the time-resolved emission matrix by using optimum incidence path aberration correction set;
- (f) re-constructing the time-resolved emission matrix corrected in the step (e) to a emission path aberration correction matrix which is composed of the emission wave vector and a deviation between the incidence wave vector and the emission wave vector;
- (g) applying an emission path aberration correction set to the emission path aberration correction matrix, thereby calculating an optimum emission path aberration correction set at which a total intensity of complex sum of a deviation spectrum between a reverse emission beam and a reverse incidence beam is maximized, the reverse emission beam and the reverse incidence beam have reverse phase corresponding to the emission path aberration correction matrix;
- (h) correcting the time-resolved emission matrix corrected in the step (e) by using the optimum emission path aberration correction set;
- and
- (i) obtaining an image by accumulating same deviation spectrum between the emission beam and the incidence beam in the time-resolved emission matrix corrected in the step (h).
