Holography has been growing in importance for environmental studies in the oceans and lakes of the world, and many teams now deploy underwater ‘holocameras’ to measure, for example, plankton and their distribution in the water column, and transport of sediment in river estuaries and offshore waters. More recently, digital holographic recording on electronic imaging sensors, coupled with numerical reconstruction on a computer, added the benefits of rapid capture and storage of 3D images, holographic video recording of moving objects, and preservation of the time dimension, to the well-known ability to interrogate planar sections of the reconstructed scene, from which particle dimensions and 3D-location can be extracted. State-of-the-art holocameras are presented and for one such system, eHoloCam, its deployment and the results obtained are discussed in more detail.
