Mtf of optical system

WebMTF is essentially a measure of the intensity contrast of an optical image per unit of resolution. Intensity is measured in power per unit area, and carries no phase information. Therefore, the MTF measurement methods that follow all rely on capturing the intensity of images that pass through the optical system under test. Video Capture… Web19 iul. 2024 · MTF testing is the measurement of the ability of optical systems to transfer various levels of detail from an object to an image. Performance is measured in terms of contrast (the intensity difference between the image’s black and white regions) and accounts for real-world factors like optical blurring.
