Linearity correction

NettetIt is found that optical sensors, like CCDs, are not perfectly linear systems as they were assumed. After bias frame subtraction, the number of ADU counts is not exactly proportional to the number of incident photons. A key component of this paper is non-linearity correction. Nettet18. nov. 2024 · I read the instructions for calibrating Linearity Correction on the E axis, and that wasn't very hard. Is there anything similar for the other axes? I noticed there are menu options for them. Also, what types of printing artefacts will that fix? Also, where can I find information about what linearity correction even is?
