Methods of pulsed holography have some advantages that are principally unachievable by other methods. Therefore, these methods can be efficiently used to study biological and medical particles, particles suspended in liquid, plankton, etc. This paper presents tentative results on development of a submersible holocamera for particle investigation. The camera employs an off-axis scheme with image transfer and a basic (transmitted) object beam. The characteristics of the optical scheme of particle image transfer are calculated numerically. A computer program is developed for modeling of the holography system with allowance for the photomaterial parameters. Laboratory breadboarding of the hologram recording system has been made. The results of calculations and laboratory experiments allow us to estimate the resolution of the holographic scheme as 100 micrometers with the recorded volume at the depth of 250 mm and 200 micrometers at the depth up to 500 mm.
