ABSTRACT:
An imaging optical module is designed to be placed in front of an optical image sensor of a semiconductor component. The module includes at least one element which has a refractive index that varies between its optical axis and its periphery, over at least an annular part and/or over its central part. The element may be a tablet in front of the semiconductor sensor or a lens in front of the semiconductor sensor. The direction of variation in refractive index may be oppositely oriented with respect to the table and lens.
