Theoretical Investigation of Experimental Deviation Influence on Binary Amplitude Diaphragms (Invited)
Both cardioid and hexadecagonal binary amplitude diaphragms (BADs) can effectively suppress axial intensity oscillations of Bessel beams, enhancing their potential applications in practical optical systems. However, various experimental deviations during fabrication, testing, and application processes can affect the suppression performance of axial intensity oscillations when Bessel beams transmit through the above two BADs. These deviations include random amplitude variations in incident light, incident beam shape deviations, incident beam center alignment errors, and pixel precision deviations in microlithography processes. Based on scalar diffraction theory and the complete Rayleigh?Sommerfeld method, we conducted numerical simulations and analysis to evaluate how these experimental deviations affect the oscillation suppression performance of the cardioid and hexadecagonal BADs. The numerical results demonstrate that both BADs maintain robust suppression capabilities against the four types of experimental deviations, even under significant deviation conditions. These findings provide valuable guidance for practical applications requiring stable Bessel beam propagation.
