Arrayed imaging systems having improved alignment and associated methods

A method for manufacturing arrayed imaging systems, each imaging system in the arrayed imaging systems having a detector associated therewith, the method comprising:

• fabricating an array of layered optical elements by sequentially applying a fabrication master, each layered optical element being part of a respective imaging system of the arrayed imaging systems and optically connected with the detector associated with that imaging system;
• wherein sequentially applying the fabrication master includes aligning the fabrication master to a common base, with alignment error not exceeding than two wavelengths of electromagnetic energy detectable by the detector.
