Image sensor modules including primary high-resolution and secondary imagers

摘要

An optoelectronic module includes one or more image sensors including photosensitive regions. The module includes a first imager including a first stack of beam shaping elements disposed over the image sensor(s) to direct incoming light to a first photosensitive region, and a second imager including a second stack of beam shaping elements disposed over the image sensor(s) to direct incoming light to a second photosensitive region. Each particular stack includes a respective high-dispersion beam shaping element, where the high-dispersion beam shaping element of the first stack forms part of an achromatic doublet at an object side of the first stack. The high-dispersion beam shaping element in the second stack is part of a laterally contiguous array of beam shaping elements that does not include the high-dispersion beam shaping element that forms part of the achromatic doublet at the object side of the first stack.

1. An optoelectronic module comprising:
one or more image sensors including photosensitive regions; a first imager including a first stack of beam shaping elements disposed over the one or more image sensors to direct incoming light to a first photosensitive region, the first stack having a sensor side and an object side; a second imager including a second stack of beam shaping elements disposed over the one or more image sensors to direct incoming light to a second photosensitive region, the second stack having a sensor side and an object side; wherein each particular stack includes a respective high-dispersion beam shaping element, the high-dispersion beam shaping element of the first stack forming part of an achromatic doublet at the object side of the first stack, and wherein the high-dispersion beam shaping element in the second stack is part of a laterally contiguous array of beam shaping elements that does not include the high-dispersion beam shaping element that forms part of the achromatic doublet at the object side of the first stack.
