Variable-apex prism controller










Image Number 4 for United States Patent #5481394.

A variable-apex prism controller which controls a variable-apex prism composed of two transparent optical members and an optically transparent substance sealed in the space defined between the two optical members, wherein the two optical members of the variable-apex prism are rotated by rotating devices around rotation axes orthogonal to each other in accordance with information from a movement detecting device. When correcting any blur by deflecting a transmitted light flux, the maximum blur correction angle .epsilon..sub.max obtained along the directions of the rotation axes of the optical members is set beforehand. The rotation amounts of the two optical members are restricted in such a way that the maximum blur correction angle for any blur occurring along a direction different from the rotation axes is substantially the same as the above-mentioned maximum correction angle .epsilon..sub.max.
