This paper aims at proving the feasibility of micro - inter diameter measurement through the analysis of laser diffraction theory. First, the instrument for laser micro -inter diameter measurement has been constructed with the guidance of this theory. Then the principle of this design will be proved being feasible by precise analysis of the measured data. In this way, the present key point concerning the measurement of micro-inter diameter can be solved. This technology can be applied to such fields as optical fiber connecting technology or the measurement of cell injectors＇ inter diameter for medical use.
