Olympus announced today that the company has been recognized as a winner of Japan's National Invention Awards for their Dust Reduction System. 

The system that Olympus pioneered uses a Supersonic Wave Filter (SSWF) to eliminate dust which might otherwise accumulate.  This is accomplished by placing a small piece of filter glass in front of the image sensor.  When the camera turns on, a small vibration goes through the glass to shake off the dust.

The Olympus Dust Reduction System was first introduced in October of 2003 and it's proven to be increasingly popular in the world of digital cameras.  Since its inception, other manufacturers have followed suit with their own systems.

Both Panasonic and Leica use Olympus technology for dust reduction on their cameras.
