Optical functional imaging and optogenetics are delegated today primarily to large and expensive microscopes based on free-space optics. Integrating the microscope functionality into an implantable form factor remains an elusive goal. As a first step towards developing such a device, a variety of head-mounted “miniscopes” have been demonstrated [1]. Using conventional lensbased optics, however, these devices consume considerable volume (more than 2cm3) to support field of views (FoVs) of sub-mm2. To achieve a truly implantable microscope,
