Camera made from 32k drinking straws takes pointillistic photographs

The article repeats the standard erroneous concept of &quot;single point perspective&quot;, which it says is what a pinhole camera produces.<p>&quot;instead of producing an image from a single point perspective, as would a pinhole, its straw counterpart produces a multipoint perspective from an array.&quot;<p>The traditional meaning of single point perspective is a drawing technique which uses a single vanishing point (rather than multiple vanishing points, one for each set of parallel lines in space).<p>The technique of using straws will produce a parallel projection of some kind, depending on the design of the camera. It isn&#x27;t a &quot;multipoint perspective&quot; just because it&#x27;s a parallel projection. This is so basic.

Interesting. This is similar to how some X-ray and gamma ray detectors did work or work in astronomy. Because you can&#x27;t focus with lenses, you use narrow tubes (collimators) to only gather the light from a certain region of the sky. Note that most x-ray telescopes use focusing Wolter optics nowadays, consisting of nested shells of reflective material. Collimating optics are also used to detect particles, I believe.

This is the way fiber optic lenses used to work: Take a bundle of a few thousand optical fibers and you have a flexible &quot;lens&quot; that can see around corners or into small holes. They&#x27;re not used much any more because it&#x27;s difficult to keep the bundle coherent on both ends, and tiny high-res TV cameras are dirt cheap now.

It&#x27;d be great to see some photos with more depth. Not having perspective is going to make ordinary rectangular objects like walls and streets look weird. This would be like a zoom lens, except presumably all the pixels merge to a blur with greater distance.

mechanical version (single, moving straw): <a href="https:&#x2F;&#x2F;youtu.be&#x2F;R4vjfVWVHGY?t=86" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;R4vjfVWVHGY?t=86</a>
