Detection System of Contrast Sensitivity for Eyes Based on Digital Micromirror Device

摘要

The contrast sensitivity of human eyes exhibits the relationship between the contrast and spatial frequency in different conditions, which is an important indicator for detecting the contrast sensitivity function. The paper designs and completes a system to measure the contrast sensitivity of the human eyes by taking advantage of DMD and Qt Creator. The system can perform the test, including spatial, time and glare contrast sensitivity of the human eyes. Finally, the test results will be expressed in the form of data curve to provide help for clinical examination.
