摘要：文中通過對JJF 1996-2022《瞳距儀檢定裝置校準(zhǔn)規(guī)范》的簡要介紹，討論了使用投影儀和影像測量儀測量瞳距儀檢定裝置計(jì)量參數(shù)的各自優(yōu)缺點(diǎn)，分析了標(biāo)準(zhǔn)套筒左右不對稱性偏差和標(biāo)準(zhǔn)套筒左、右瞳距值之間的偏差計(jì)量術(shù)語的區(qū)別，建議增加“中心距測量結(jié)果一致性”計(jì)量特性。

關(guān)鍵詞：瞳距儀檢定裝置；左、右瞳距值之間的偏差；中心距測量結(jié)果一致性

Abstract：  Through the brief introduction of JJF1996-2022“Calibration specification of pupilometer verification device”， the merits and limitations of using projectors and image measuring instrument to measure the measurement parameters of pupilometer verification device are discussed. Specifically， this paper analyzes the difference between the measurement terms of the left-right asymmetry deviation and the left-right pupil distance of the standard sleeve. Based on this analysis， the paper recommends the inclusion of a new measurement characteristic： "the consistency of center distance measurement results." This addition aims to enhance the accuracy and reliability of pupilometer distance meter verification.

Key Words： Pupilometer distance meter verification devices; Left-right pupil distance deviation; Consistency of center distance measurements
