ABSTRACT:
An imager includes an imaging device and an lenticular array mounted on the imaging device. The imaging device includes a substrate of a semiconductor material having a pair of opposed major surfaces and an array of detectors at one of the major surfaces. The lenticular array includes a substrate having a pair of major surfaces and an array of lenses at one of the major surfaces. The lenticular array is mounted on the detector device with the other major surface of the lenticular array substrate being in closely spaced relation to the other major surface of the detector device substrate. Between the two opposed major surfaces of the two substrates is a bonding cement which extends only around the detector array. Dispersed within the bonding cement are hard spacer particles which are engaged by the opposed major surfaces of the two substrates to space the substrates apart.
