Abstract

A simple photoelectric system is devised in this essay. An optimum diaphragm is chosen through measuring the optical transfer function of double-ringed diaphram in different dimension. In this way, it is proved that the quality of speckle pattern diffraction halos can be increased and a complex calculation can be avoided. The calculation and the photos provided here prove the reliability of the measurement.
