Does anyone know what it looks like when you use a line scan camera to take a picture of the landscape from a moving car or train? I suspect the parallax produces some interesting distortions.

It’s just a blur. Like the background of the photos in this article.

You can get some cool distortions at very slow speeds, but at car or train speeds you won’t see anything

I've taken a couple of pics from a moving train...

Sorry for the purple trees. The camera is sensitive to near infrared, in which trees are highly reflective, and I haven't taken any trains since buying an IR cut filter. Some of these also have dropped frames and other artifacts.

Exactly what wanted to know. Is it technically feasible to 'scan' a whole landcape of lets say an hour long trainride?

The background in the article is not a "blur".
