Phone cameras show both the power and limits of computational photography. You can’t run away from physics forever.

Phone cameras show both the power and limits of computational photography. You can’t run away from physics forever.
- whoisburbansky 5y agoPhone cameras don’t have multiple lenses working together that you can interpolate between to create a single giant virtual lens. The technique OP is referring to is already used for the largest ground based radio telescopes.
- bane 5y agoExactly correct. And Labeyrie has a design in place for the exact type of fleet I'm talking about.
- mhio 5y agoDo you have a link to the design? I'm assuming it's a radio telescope?
- bane 5y agoNo the design is optical. Here's a white paper on the concept. https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.cosmos.esa.int/documents/1866264/3219248/LabeyrieA_LabeyrieESAwhitePaper2019.pdf/371f2caa-e30a-40fd-b040-99af76734f97%3Ft%3D1565184643980&ved=2ahUKEwjl_pCCu9PxAhWYPM0KHXsWCJMQFjAGegQIDhAC&usg=AOvVaw2Z81efFvZCMGyv1lcZPqtj https://www.google.com/url?sa=t&source=web&rct=j&url=https:/... Labeyrie has also proposed a fleet in L2 and on the Moon.
- PabloRobles 5y agoNot the OP, but I guess he is talking about the hypertelescope concept: https://hypertelescope.org/hypertelescope-en/ https://hypertelescope.org/hypertelescope-en/ For additional background, there are already optical interferometry telescopes in use, see VLTI by the European Southern Observatory (Chile, shared facility with the four VLT telescopes and some smaller telescopes).
- jagger27 5y agoWell, a lot of phones do have multiple sensors and lenses. For example, the iPhone's computational depth effect uses multiple cameras for a single shot.
- whoisburbansky 5y agoThat’s qualitatively different from the kind of stitching together that happens with, e.g. the VLA. The computational limits of phone photography don’t apply here.
