These filters are electrical wave filters designed using the image method.
2.
A lens is basically a low-pass plane wave filter ( see Low-pass filter ).
3.
Further harmonics attenuation can be obtained by using an LCR low-pass sine wave filter or dV / dt filter.
4.
Olympus invented the system, called a Supersonic Wave Filter ( SSWF ), and licensed it to Leica and Panasonic.
5.
The " Supersonic Wave Filter " consists of a very thin piece of filter glass placed in front of the image sensor.
6.
Network synthesis was originally intended to produce filters of the kind formerly described as " wave filters " but now usually just called filters.
7.
Like all other Four Thirds DSLRs, the Lumix DMC-L10 employs a Supersonic Wave Filter ( SSWF ) system to combat dust entering the body.
8.
The E-520 uses Olympus'Supersonic Wave Filter dust reduction system to shake dust from the sensor during startup and when requested by the user.
9.
The E-300 uses Olympus'patented Supersonic Wave Filter dust reduction system to shake dust from the sensor during startup and when requested by the user; this largely eliminates the problem of dust accumulation on the surface of the image sensor.
