Table 1: Time of packet transmission and transmission frame rate. Figure 16: The frame of the 3D image: (**a**) texture (2000 \(\times\) 2000 pixels); (**b**) the pattern of structured fringes (25 \(\times\) 2000 pixels). The first column of the Table indicates the running number of an experiment with test transmission of the holographic 3D information. The column entitled \"Resolution, pix.\" shows the resolution of frames with texture image (T) and mask (M), respectively. The column entitled <<Frame format>> indicates the formats of files into which the initial image arrays were compressed. The number of frames transmitted in a packet is shown in the column entitled \"Number of frames\". The column entitled <<Packet volume, MB>> represents the volume, in MB, of the transmitted packet with frames, where indices T and M mark the volumes of a frame with texture and a frame with mask separately. The column entitled \"Communication channel capacity\" shows the transmission capacity of the Wi-Fi communication channel used, in MB/s. The column \"Transmission frame rate\" lists the frequency of frames transmission, determined on the basis of the measured rate of data transmission along the Wi-Fi communication channel, in frames/s. One can see that the frame rate turned out to be more than 25 frames per second in experiments Nos. 1-3, 5-6, and 8-9 (rows in the table are highlighted in green). This means that it is possible to transmit the 3D holographic information in PNG and JPEG formats both for the TV standard similar to SECAM and for HD and Full HD. The BMP format is unsuitable for frame transmission in our case for the resolution higher than that involved in Experiment No. 1, because of the absence of any conventional type of compression of the transmitted 2D frames, and, as a consequence, too bulky files with the frames to be transmitted. Nevertheless, the BMP format is quite suitable in the proposed technology for use in the systems of holographic phototeleography, as one can see in the results of experiments in rows 4 and 7. The versions of 3D data transmission shown in Table 1 may be applied in various 3D augmented-reality facilities, in particular, in telemedicine, in the systems of remote control of complicated objects, including safety systems, 3D phototelegraphy, etc.
