Abstract: According to different coding methods, multiplexing holography can be divided into two types, i. e. coding record of multiple record elements and coding record of multiple lightbeams. Combining these two methods, a new technique for holographic multiplexing is proposed. The channel number of a hologram made by this kind of method is the product of the recording element number and tht recording lightbeam number. As an application, an expeimenlal result ot multiplexing holographic interferometry by means of this technique is given.
