DOI: 10.1117/1.oe.64.10.103104
Abstract: Abstract. We present high-resolution Fourier ptychographic microscopy (FPM) using a hemispherical light emitting diode (LED) illuminator. We have further increased the synthetic numerical aperture (NA) by filling the illuminator with oil, thereby stretching the illumination… read more here.
