The main thrust of the patent is the variable Apodization filter, and it will be expensive.
A different translation of the patent:
Especially the present invention is using the shape variable element which made variable form of the interface which two different media form about an optical system, and it is related with the imaging optical system which makes it possible to control the light volume of the light flux which passes an optical system.
The technique of making the apodization effect variable is disclosed by the Patent document 2. In the Patent document 2, by transmissivity's differing, and arranging two kinds of mutually unmixed liquids in a closed space via the interface of an approximate sphere surface, and controlling the output of impressed electromotive force, liquid interface shape is changed and the optical element which made the apodization effect variable is proposed.
There is a ton of very technical calculations in the patent, and it gives me a feeling that it is not something that will be cost effective to build and sell for a acceptable price.
I really don't expect to see one on the market.
