Fourier Plane Imaging Microscopy
MetadataShow full item record
We show how the image of photonic crystal can be reconstructed using a single (non- scanning) Fourier plane image obtained with a second camera that was added to a traditional compound microscope. We discuss how Fourier plane imaging microscopy (FPIM) technique is an application of a remarkable property of the obtained FP images. We show that FP images captured by camera contain more information about the photonic crystals than the images recorded by the camera commonly placed on the real plane of the microscope. We argue that the experimental results support the hypothesis that surface waves, contributing to enhanced resolution abilities, were optically excited in the studied photonic crystals.
