The application of holography to microscopy is outlined with special reference to the identification of fossil ostracods using a stereomicroscope. The effect of laser speckle on the image quality is demonstrated and a speckle reduction technique based on the incoherent superposition of many differently-speckled reconstruct-ions of the same object is discussed. A holographic attachment for a standard stereomicroscope is described in which this speckle reduction technique is implemented by means of a holographic lens array, and results are shown.
