according to the invention , a multilayered image sensor is back mounted to a plate , and the plate in turn , is installed in a holding pocket of a device . in that the scheme takes advantage of a high controllability of a mounting plate &# 39 ; s thickness , the mounting scheme provides a tight control of holding forces with which an image sensor is secured in an imaging device . in that the scheme provides for back mounting of image sensor on a planar surface , the mounting system provides tight control of an imaging assembly &# 39 ; s pixel plane to fixed point in space distance .
