Optics and photonics — Medical endoscopes and endotherapy devices — Part 5: Determination of optical resolution of rigid endoscopes with optics
Preview
Summary
This document applies to rigid endoscopes designed for use in the practice of medicine. Endoscopes
having a fibre-optic or opto-electronic imaging system are excluded. It specifies a test method for
determining the optical resolution of endoscopes.
This document provides a measurement method for characterizing three aspects of the optical
resolution of a rigid endoscope. Characteristic A is used to provide a simple measurement of the limiting
resolution of the endoscope image. Characteristic B provides a measurement of low spatial frequency
resolution and characterizes the sharpness, or contrast, of the endoscope image. Characteristic C
provides a measurement of the spatial frequency response of the endoscope image.
