This investigation determined that the application of a Gaussian apodiser did not improve the imaging performance through a coherent multiaperture optical imaging system. This was the case whether the object was a point source or an edge, whether the dilution was increased or held constant, or whether aberrations were present or not present. Further, the investigation determined that the amount of spacing between the subaperture which either an aberrated or unaberrated optical system could tolerate and still obtain acceptable imaging fell dramatically. The analysis was accomplished with computer codes which made use of Fourier transform techniques to perform the imaging. The edge imaging results of this study can be applied without loss of generality to that of an imaging system with an annular exit pupil. Theses
