The following optical-mechanical device, which is equivalent to the patented one, but with a modified kinematics, consists of:<\/p>\n<ul>\n<li>An inner lenticular lens together with a slit layer fixed on it is a stationary part;<\/li>\n<li>An outer lenticular lens (together with a scattering film) is movable and performs all necessary sequential shifting in relation to slits.<\/li>\n<\/ul>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\">The outer lenticular lens is moved by a rotary engine through a crank rod. An encoder designed for manual regulation of the starting position of a lenticular lens is mounted on the engine shaft. The movement of the lenticular lens is implemented on frame-type sliding guides\/sled. The engine is set to ensure stable operation at a frequency of \u2248 150 Hz for demonstration under full load (with lenticular lens) for 1-1.5 hours. With acceleration of start-stop cycles (up to 500 Hz) continuous operation of the engine is significantly reduced. Engine control is similar to the layout of a lab design, it is controlled by visual signals coming from the screen (programming\/tuning of controller has been managed from the computer). A power supply (for engine and controller) will ensure full autonomy for SSE and its independence from the demonstration device. A computer screen with 144 Hz refresh rate was selected for the prototype.<\/p>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\">As in the case of the laboratory sample, the main task of the prototype is exact perspective switching in the spectator area, as shown in the illustration below:<\/p>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-260 size-full\" src=\"\/\/www.3dtau.com\/3db9Yn_B\/wp-content\/uploads\/2015\/06\/3dtau_lenticulars_animation_prototype_10frames.gif\" alt=\"\" width=\"663\" height=\"411\" \/><\/p>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\"><span style=\"color: #000000;\">During the demonstration, each angle was separated (in compressed fragments) in fixed slits and instantly directed by lenticular lens to the spectator area. Direction switching was recorded using a camera: constant visual edge-to-edge perspective with the transition to the next perspective number. The device also demonstrated the 3D effect (voluminosity) of image in both static and dynamic forms.<br \/>\n<\/span><\/p>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\">It should be noted that the limited speed qualities of prototype&#8217;s optical mechanics, together with low performance of demonstration screen and graphics card, produced the so-called \u201cdark flickering\u201d (from the 4<sup>th<\/sup> perspective) of the image in spectators area. Nevertheless, the prototype performs the main tasks.<\/p>\n<p class=\"western\" lang=\"en-GB\" align=\"JUSTIFY\">\n","protected":false},"excerpt":{"rendered":"<p>3D Tau made a prototype device for demonstration of the SSE technology.
