Interferometric imaging systems with exchangeable imaging modules

Abstract:

A modular assembly for an imaging system can allow precision alignment to occur in isolated manufacturing stages, with the separate components being assembled together in later stages. An exemplary system includes a support structure, multiple imaging modules exchangeably coupled to the support structure and each including lenslets and a photonic integrated circuit (PIC) device arranged to receive light from the lenslets, multiple fiber arrays each connected to corresponding one of the multiple imaging modules, and a camera system connected to the fiber arrays. The lenslets the PIC device can be integrally coupled prior to assembly with the support structure, so that precise alignment of the lenslets with respect to the PIC device is performed in isolation.
