Abstract :
Summary form only given. Volume holograms possess outstanding selectivity to the properties of probing beams, such as angle, wavelength, and wavefront curvature. The selectivity can be used as filters in a microscope system. Multiplexing holograms makes it possible to image different sections of an object into different sensors at the same time, making single-shot image capture of the 4-D object (3-D spatial and spectral) possible. In this paper, we demonstrate two-dimensional imaging of fluorescent microspheres by a single volume hologram, and investigate the system characteristics.
