I wonder if there is an optical solution to this.

If you were to take a piece of plate glass on an angle to the optical axis of the lens - like a tilted filter - wouldn't that shift the image slightly in a direction opposite to a normal to the glass plate?

Not quite. The glass plate needs to be placed between the lens and the sensor. Anything front of the lens needs to introduce an angular movement, not a lateral shift, because the lens transforms angles within the FoV into distances on the focal plane.

"What we claim is:

1.  An imager comprising an array of sensing elements arranged in rows and columns, a lens adapted to focus an image on said array and a member which includes at least one refractive region transmissive to radiation to which the sensing elements are responsive, wherein the member is movable such that a refractive region of the member is repeatedly interposed in a radiation path between the lens and the array whereby the image focused on the array is displaced diagonally by said member, relative to said rows and columns of the array."

I think I got there before you!
