A video plankton recorder (VPR) is towed underwater video microscope system, which photographs small to fine-scale structure of plankton, from 50 micrometers and up to a few centimeters in size. A VPR consists of five general components: cameras (with magnifying optics ), strobe, additive sensor and flight control, underwater platform and interface software for plankton identification. In order to obtain high-quality and low-noise images, charge-coupled device (CCD) sensors are used in the camera system. In the early design system, the CCD cameras were mounted in one of the arm of the platform. The developments in the recent years made the cameras system possible to be mounted in the platform body along with other sensors and flight control. The magnification power on the cameras should be vary, with high magnification power on the camera, we can obtain detail observation result on the plankton sample, such as protozoan that has
