Using decapped DRAM chip as photo sensor looks more promising:<p><a href="https:&#x2F;&#x2F;hackaday.com&#x2F;2014&#x2F;04&#x2F;05&#x2F;taking-pictures-with-a-dram-chip&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackaday.com&#x2F;2014&#x2F;04&#x2F;05&#x2F;taking-pictures-with-a-dram-...</a>

Visually, I&#x27;m reminded of this project. <a href="https:&#x2F;&#x2F;www.thisiscolossal.com&#x2F;2017&#x2F;02&#x2F;drinking-straw-camera&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.thisiscolossal.com&#x2F;2017&#x2F;02&#x2F;drinking-straw-camera...</a><p>I know CCDs for astrophotography have large photosites to increase the signal&#x2F;noise ratio. It seems like this array would have the same qualities.<p>Do you know what the dynamic range is, how many stops the sensor can capture?<p>This is really interesting, so I&#x27;d really like to see a write-up instead of just a video.

How about making a (slow) medium&#x2F;large format camera with a linear sensor from a scanner?

Well done. The quality of explanation and production value were good. It seems like by adding more processing power, you can double or triple the scan rate.

I bet by changing up the sensor pixels this would be a pretty cost effective way of making a low res FLIR camera, or really any imaging band. Using a different pin hole you might even be able to image things with xrays, neutrons, or strong 100Ghz through THz radio waves.

Instead of a front lens element you might get better results using a lens salvaged from an old medium format folder. The whole lens and shutter assembly comes off as a single standard sized unit.<p>These should be a good fit for the needed image circle and give better images as well.
