Abstract

Obtaining gigapixel images is a challenging task because of the aberrations present in a conventional optical system, small sensor sizes and limited data-capture rates of cameras. Multi-aperture Fourier ptychography (MAFP) was proposed recently by us to solve the issue of increasing the data acquisition bandwidth by parallelizing data capture using an array of lenses coupled with discrete detectors. We present an advanced MAFP system based on the Scheimpflug configuration to improve the MAFP system performance at high NAs. This system requires a complicated optical system due to the large number of degrees of freedom present in the system. Hence we developed a 3D-printed system which solves this issue and decreases the cost of the setup tremendously. In this manuscript we present the details of our 3D printed design and preliminary images obtained using this system.
