Abstract: | A holographic system that images front-illuminated, fast-moving microscopic objects is described. Focused micrographs can be generated under circumstances when ordinary microscopy (due to object movements) and transilluminated holographic microscopy (due to object opaqueness) cannot be used. Details of the experimental arrangements, easy-to-use working formulae for obtaining optimum image reproduction, and results from the application of the system to studies of droplet and solid particle suspensions in liquids are presented. |
