CS-ECTS-TC03 Spatial Frequency Response Test Chart (Star Chart) — For Endoscope Image Quality Testing in Accordance with YY/T 1603-2018

ColorSpace has developed the CS-ECTS-TC series of endoscope test chart for medical and industrial endoscope imaging systems. The CS-ECTS-TC03 Spatial Frequency Response Test Chart (Star Chart) is designed for spatial frequency response (SFR) testing of endoscope camera systems. It is designed in accordance with the relevant test methods specified in YY/T 1603-2018, using a sine-wave star target for spatial frequency response testing. Appendix C of YY/T 1603-2018 specifies the test method for spatial frequency response using a sine-wave star target.

The test chart features a sine-wave Star Chart pattern. By analyzing image modulation at different spatial frequencies, it provides spatial frequency response (SFR) data for the endoscope camera system and can be used to evaluate its spatial frequency response performance. In accordance with the relevant test method in YY/T 1603-2018, the test results can be further used to determine the spatial frequencies corresponding to 50% and 30% SFR.

The test chart features a transmissive design with a glass substrate and can be directly mounted on the CS-ECTS Endoscope Test System. It is suitable for spatial frequency response testing of medical and industrial endoscope camera systems.
