Foreword

This standard replaces GB/T 11168-1989 "Optical system quality test method". The main differences between this standard and GB/T 11168-1989 are. - standardize the reference standard in Chapter 2 of GB/T 11168-1989;

--- the GB/T 11168-1989 Chapter 3, Chapter 4, Chapter 5 and Chapter 6 into the same chapter, the title changed to "quality test side law". Appendix A of this standard is a normative appendix. This standard is proposed by the China Machinery Industry Federation. This standard is nationalized by the National Committee for the Standardization of Optics and Photonics (SAC/TC103). This standard is responsible for drafting units. Shanghai Polytechnic University. This standard participates in the drafting unit.

1 Scope

GB/T 11168-2009 is the Chinese national standard on image quality of optical systems method of determination, in the field of image technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 September 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2009. Classification: ICS 37.020, CCS N30. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the test methods used to evaluate the star, resolution, geometric aberration and wave aberration of the optical system. This standard is applicable to infinity imaging optics systems, far-focus optical systems and limited-distance imaging optics systems for use in visible spectral regions. The use of optical systems for other adjacent spectral regions may be used.
