There may be additional sources about this test beyond those I'd included in the original post, and maybe this is a technique tried before on other cameras, or maybe it's totally unique. I suppose the "broccoli" will turn out to be unique for sure. Let's see what else turns up | |

Sep 9, 2020 at 7:11 | comment | added | uhoh | I think that the circa 200 wavelength wide pinhole also offers the advantages over a projection lens of being very easy to model unambiguously with basic optics (MTF, scattered light, etc) not require any focus or introduce any errors if focus isn't correct, and automatically produces a fairly low light flux which might be suitable for the array, but those aren't mentioned in the linked articles. | |
