Ah yeah, I recently changed the url scheme for my blog posts, from

    https://daniel.lawrence.lu/blog/y2025m09d21
to

    https://daniel.lawrence.lu/blog/2025-09-21-line-scan-camera-image-processing/
so maybe that's why OP didn't realize that it had already been posted recently. With the older scheme, not only is SEO bad, but it was really hard to remember which date corresponds to which blog post, and people can brute force search for my hidden (unpublished) blog posts easily.

Is the vertical banding due to the camera being unable to have a fixed exposure gain configured? Or just due to slight variances in the sampling times due to unstable oscillator frequency?
