Full colour sensor research
There has been some research on full colour imaging sensors, with some papers
published as early as 1998. The papers of 1998/99 focus on semiconducting polymers or organic semiconductors: http://journals.cambridge.org/action...ge=online&aid= 8062197 http://onlinelibrary.wiley.com/doi/1...4095%28199812% 2910:17%3C1431::AID-ADMA1431%3E3.0.CO;2-4/abstract while the Nikon patent is about a setup with multiple dichroic mirrors: http://www.dpreview.com/news/2007/8/9/nikonimagesensor But there are no commercial products (except for Foveon, which uses a different technique). So have all these (non-Foveon) approaches resulted in failures? -- Alfred Molon ------------------------------ Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

So have all these (non-Foveon) approaches resulted in failures? so far, yes. the tradeoffs are not worth it and they might never be. the benefit (higher chroma resolution) isn't anything humans can see anyway, and to get that requires giving up stuff they *can* see, including luminance resolution, dynamic range, cost to manufacture, speed of processing and more. it's a very bad deal. even foveon agrees, which is why their new sensor is 'bayer-ish', where it interpolates nearby pixels. it's actually rather amusing how much they have to backpedal on their claims now. bayer is an ideal tradeoff for human generation and consumption of images and it's going to be *really* hard to beat. |

I saw an article recently about a new sensor type involving graphene "cones" on top of a backdrop pixel. You would get single color information from the cone, and "everything else" information from the backdrop pixel.

Graphene is poised to make major disruptions in electronics and materials over the coming decade - it's unlikely that it won't have several photography applications. -- "Big data can reduce anything to a single number, but you shouldn’t be fooled by the appearance of exactitude." -Gary Marcus and Ernest Davis, NYT, 2014.04.07 |

Best of both worlds? this, maybe? http://phys.org/news/2014-04-pixels-...as.html#ajTabs YES! That was the article. Not graphene after all, just reduced dimension silicon on top of more silicon. -- Money is Speech Corporations are People Ignorance is Strength |
