Three Types of Image Smear

Linear motion is a major issue with pixel smear, especially in the case of satellite remote sensing, which is used here to illustrate smear. I may get around to doing another video for jitter and oscillation, depending on how well this one is received. The degrading effect of smear is measured through its impact on contrast, which is gauged by the modulation transfer function (MTF). So, I talk about that here. We are in the middle of a module on optical detectors and focal plane arrays. So, because you are "sitting in" on a mid-course lecture, there could be some unfamiliar terms and concepts. This lecture assumes some familiarity with MTF, the influence of pixel size on MTF, and the cut-off spatial frequencies that define the loss of contrast. That's where it picks up. This shameless promotion is snipped from my 10-week course on optical systems engineering that is open to anyone who has taken a university-level course on optics. This on-line course, offered twice per year, has weekly Zoom sessions and a lively course discussion board, gets you to do homework which receives feedback directly from me, is a great networking opportunity, and comes with about 12 hours of recorded lectures, of which this video is a sample.
