Abstract
Under broadband illumination, a multiplane microscopy incorporating volume holographic gratings (VHGs) to observe three-dimensional structures of biological samples with different depth simultaneously is presented. VHGs formed in thick recording materials, including PQ-PMMA, provide strong angular and wavelength transmittance filtering properties, which enable acquiring spatial–spectral images of fine structures within biological samples. Here, we experimentally demonstrate this microscopic imaging capability to obtain multiple depth-resolved mixed pollen grains images of fine structures from eight depths in one shot.
