1. A system, comprising:
a curved array photodetector;
a first readout integrated circuit, the first readout integrated circuit being substantially flat; and
an interposer, between the photodetector and the first readout integrated circuit,
the photodetector having a plurality of electrical contacts,
the first readout integrated circuit having a plurality of electrical contacts, and
the interposer comprising a first conductor connecting a first contact, of the plurality of electrical contacts of the photodetector, and a second contact, of the plurality of electrical contacts of the first readout integrated circuit,
wherein:
the interposer has a first surface, and a second surface,
the first surface is substantially spherical;
the photodetector is substantially spherical, and conforms to the first surface; and
the second surface is substantially flat.
