Abstract

In this study, we compare the wavefront reconstruction error (WRE) of the slope zeroing and subaperture removal recovery methods for the lack of light in subapertures. For lack of light in a single subaperture, results show that the WRE of the slope zeroing method increases with the increase in the radius of the subaperture center relative to the center of the full aperture. The WRE owing to the lack of light in the subaperture in the central part of the aperture is small, whereas this error along the edge of the aperture is large. In contrast, the WRE of the subaperture removal method owing to the lack of light in the subaperture is observed to be uniform and small in the aperture. The WRE increases with the increase in the number of subapertures lacking light. In addition, we investigate and compare such cases of multiple subapertures that lack light. Results show that although the calculation of the subaperture removal method for lack of light in subapertures is complex, the WRE of the subaperture removal method is much smaller than that of the slope zeroing method.
