Abstract:
1. A method of generating, by means of a field of light imaging device, a representation of an attribute of a target, said target containing at least one element that modifies the direction of the path of optical signals, said method comprising: effecting multiple relative locations and relative orientations between said target and said field of light imaging device; capturing at least one field of light data sets of said target at each of said multiple relative locations and orientations by means of said field of light imaging device; generating a first set of multiple images of a surface within the target from said field of light data sets wherein each of said images has an associated meta data set related to the paths of the optical signals used to generate said images, using a first estimate of said element that modifies the direction of the path of optical signals in said target; modifying, at least one time, said first estimate of said element that modifies the direction of the path of optical signals in said target, using a figure of merit derived from processing said first set of multiple images; generating at least one second set of multiple images of a surface within the target from said field of light data sets wherein each of said images has a modified associated meta data set related to the paths of the optical signals used to generate at least a second set of multiple images and wherein said second set of multiple images has an improved figure of merit and outputting said representation of said attribute of said target.
