Determination of optical distortion image quality evaluation system

1 Scope

This standard specifies the optical system radial distortion measurement method. This standard applies to the spectral range of 100nm ~ 15000nm inside, and has a rotational symmetry properties of the optical system. For compliance with spin Turn symmetry properties of the electron-optical imaging system, may also refer to use. This standard does not apply to the deformation of the optical system.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Distortion distortion A widthwise magnification field of view with the changes caused by the increase of loss was like one kind of aberration similar. Note. If the image plane at infinity, as indicated by the position of the tangent of the angle of view. 2.2 Reference plane referenceplane Measuring, calibration plane, it is the physical characteristics of the measuring apparatus corresponding to such mounting flanges or other dedicated components. 2.3 Absolute distortion absolutedistortion Va The observed image point to the radial distance between the ideal image point. Expressed in units of millimeters or microns. 2.4 Relative distortion relativedistortion Vr Va absolute distortion from the ideal image height h'0 expressed as a percentage. 2.5 It was high objectheight Object point to a test sample from the rotational symmetry axis between. Expressed in units of millimeters. 2.6 Like high imageheight h ' Dot to the test sample from the optical axis between the rotation symmetry. Expressed in units of millimeters. 2.7 Field of view angle objectpupilfieldangle ωP Principal ray and the optical axis angle of the edge of the object point twice.
