“光学测量与仪器的对准精度”是从事仪器设计、光学测量及装配校正工程技术人员必须掌握的基础知识。这里所说的对准包括横向对准和纵向对准。横向对准有时称为瞄准,而纵向对准习惯上叫调焦和定焦。两种对准之间虽往往有内在联系,但性质还是有差别的,误差计算方法也不同。 “Optical Measurement and Instrument Alignment Accuracy” is the basic knowledge that a technician in the field of instrumentation, optical measurement, and assembly correction engineering must master. Alignment here includes both lateral and longitudinal alignments. Lateral alignment is sometimes referred to as aiming, while longitudinal alignment is conventionally called focusing and focusing. Although there is often an intrinsic relationship between the two kinds of alignment, the nature is still different and the calculation method of the error is also different.
