Threedimensional photograph of more objects by nesting ellipse path

A way to form the threedimensional photograph of more objects by nesting of big and small ellipse path is introduced according to the character of ellipse and constraint conditions of experimentation. The holographic recording for more objects can be realized with this method by the aid of a holographic recording system in our laboratory. It can avoid the complex work for repeatedly adjusting the reference beam and the object beam to the equal opticalpath length during the experiment. Several objects appearing in the same space at the same time or the information from different viewing angles of one object were recorded in one hologram. The threedimensional hologram was got in such a way.
