The other point they make is;
"When electric signals obtained with the photoelectric conversion are so amplified as to have the same sensitivity as that of the conventional photoelectric transducers, it is possible to provide image signals with less noise."

Look, I wouldn't get too excited about these patents. Some of them are simply 'marking out territory' instead of something that's production-ready. To get an idea past the theory or prototype stage and viable for large-scale manufacture and long-term use is a whole other kettle of fish.
This may make it into future products, but who knows. Personally I wouldn't bank on it in the short-term; maybe in the 2009/early 2010 timeframe.

It looks to be very expensive to make one of these devices even if it were possible. Imagine not only having to make the sensor, but having to make an array of tilted dichroic mirrors. My understanding is that dichroic mirrors are costly, and then having to make loads of tiny ones, eeek.
This reminds me of the digital projectors which project an image fed from a PC, and they do it by having an array of tiny little mirrors, one per pixel, which reflect or not incident light to create the final image. They cost a small fortune.
Still, it is nice to dream. All too often reality exceeds my expectations.

2009 / 10... I think thats what the OP meant when he titled the thread "D something". That chances of it coming this year would be interesting to say the least, but possibly for another D series camera.

Interesting thread. Thanks for starting it Nik. For the moment the link in the opening post is not working.
It'll be interesting to see how this new technology develops but it could be years, if ever, before we the consumer see the fruits of Nikons efforts. Sometimes these things just never work out and abandoned for various reason. Hopefully not. What I'd like to see more than anything at this point is a wider dynamic range.

Just give me less freakin noise. There's so much I love about my Nikon gear, but the noise and loss of detail is a borderline deal breaker for me. I print a LOT of 8x10's and larger and it's clearly visible when I have to push the ISO up. Frankly, it bums me out. I'm dangerously close to trying out a 5D.

Tom, I suggest if you are having noise issues in your prints at 8x10 it's not a problem with the camera. I suppose it COULD be a specific problem with your particular camera, but I'd be looking at either your exposure or processing if you are getting visible noise in a print that small. I just printed a 12x16 taken at ISO 1600 and it is as clean as a ISO 100 print. No visible noise. No NR applied in post either. You can buy a 5D if you wish, but if it's only to avoid noise in a 8x10 print there are other issues that need to be addressed first as it's likely not with the D200. Like I said it could be your specific camera but I'd be looking at exposure or processing first. I'm guessing exposure.
Not trying to bash you. Just trying to maybe help you avoid an unnecessary departure of cash. Because if you are doing something wrong now between the time you pressed the shutter button and print it's not going to be solved with a new camera.
Some mongrel took MY research, and then then posted it on DP Review the next day as his own!
WHAT THE ?
A coincidence or someone from DPreview visted FM and took info from you...that's sad bro. Sometimes I worry about my shots being copied and that happened a few days ago ~ some guy won a newspaper photo contest and his photo looked exactly like mine...that spot was pretty hard to find and anyone new to photography will come across with Nikonians and my shots are easy to access. Some lucky guy...and I hope it was just a coincidence that he found that lucky spot/angle.

I was just having a laugh actually. I was just somewhat "open eye wowed" when I saw it in the news section of DPR. Hey, he could have given me a credit.
But more seriously, someone pinching pics, and claiming as there own... well, cut off his gonads for that!!

Phil simply got a tip from a forum member who read the article here; I doubt he goes about reading posts on FM That said, attribution would have been very nice (on the forum member's side)

Ok, so Nikt made me come over here (I'm a Canon-mount lurker mostly) to take a look-see
The wikipatent link is dead, so I had to hop over to another patent database and read up on it. It's a creative way of thinking, making use of existing ideas and adding something new.
The downsides... well, I can see multiple challenges. First off, I know that the traditional Bayer pattern isn't all that efficient, but this looks tricky as well.
The photosites are very small. They are forced to be small because they have to be lined up, making them take up an elongated space. OOPS. So you'd have to either stagger your microlenses and/or keep the individual photo sites small and thus keep the chain short. Otherwise, the spacing of the microlenses would not be the same in every direction. (Makes me think of the D1X with it's double horizontal resolution.)
But there goes your dynamic range down the drain... Bigger photo sites mean larger charge storage, so chalk up challenge number 2.
The microlens itself needs to be quite complicated in design too. With all three photosites behind it at different distance, how will you get the microlens to focus on all of them? And I hate to be the person who has to come up with a solution to compensate for the angle of incidence, for wide open v stopped down aperture.
And I hate to be the one who has to build/design the lithography process for this puppy too. Depositing three types of multilayer dichroic mirrors at a 45 degree angle will require quite a bit of engineering prowess.

In your place I would make an email complaint to dpreview and include a link to your posting indicating that you did the research, and that basic manners requires they post a correct attribution. And did he take a picture of yours? If so then that is surely breaking of copyright, and downright scummy behaviour IMO.
Personally I like to think that if I come across something novel, that I would not pretend it was my idea.
... thats funny. Now if he see this, he'll be thinking "bloody amateur... doesn't know what he's talking about!" And he'll be right!!!
