[科技新知] Panasonic color spliter sensor

There is a new sensor structure that introduce by Panasonic to replace color filter by color splitter. This kind of sensor remove general color filter and add the color deflector before the diode. The conventional color filter would cause 50%~70% light loss and new sensor reduce lots of the light loss. The following pictures show how it works.

The device can also be manufactured using current semiconductor fabrication processes. It doesn't use special materials or processes. It's a great news to bring this sensor to realization.

  

The comparison between the color splitter sensor and color filter sensor.

Panasonic demo with only two-deflector method but various combinations are possible.That means, it could be adjusted by different application.

Although it could provide much better sensitivity, I still have some question about it.

- Would the resolution be sacrificed?

- The diode of different pixel is not balanced, is there any side-effect occurred?

- Would it be much more complicated for the image processing processor supported?

Anyway, I'm still interesting with this sensor and I'll keep eye on it.
