Scope

This Part of GB/T 4315 specifies general guidelines for the construction and
use of the optical transfer function (OTF) measuring equipment of the imaging
system.
This Part describes various important factors that may affect OTF measurement.
At the same time, it specifies the general rules for measuring equipment
performance requirements and environmental controls.
This Part specifies the points that must be paid attention to to ensure accurate
measurement, as well as the correction factors for the measured data.
The optical transfer function measuring equipment described in this Part is
limited to analyzing the radiation distribution on the image plane of the optical
imaging system under test. This equipment does not include interferometer-
based instruments.

Summary	This standard specifies the imaging system optical transfer function (OTF) measurement device structure and use of common guidelines. This section describes the OTF measurement may affect various important factors, but specifies performance requirements for measuring devices and environmental control of the general rule. This section provides that in order to ensure accurate measurement points must be noted, as well as the measured data of the correction factor. This section describes the optical transfer function measurement device, limiting the analysis of the measured optical imaging system radiation distribution on the image plane. These devices do not include interferometer -based instruments.
