Projection structure diagram

device contains a projector 6, in ko-45 geometric shapes formed

The source of light 7, a capacitor 8 and rotatably installed light filters 9 and shaping stencils 10 are located on the same optical axis, and the control input of each actuator 4 of the retroreflective shaper is connected via a control signal generating circuit 11 to the sound source. The image is projected 55 pa screen 12,

Forming light reflector works as follows.

When no signal arrives at the actuating element 4, the luminous flux, the passage of the slit through the n t-sided reflecting elements 1 located in the light projection tube 2, is reflected from the inner surfaces of the n t-sided reflecting elements 1 and a light image is observed on the screen 1 2 mosaic structure in the form of surroundings or geometric figures (it depends on the specific value of n - the number of elements 1 located in the tube, and w the number of faces of the reflecting elements 1),

When a control signal appears, the executive element 4 of the kinematic unit 3, installed in the opening 5 of the light projection tube 2, begins to exert pressure on the external surface of the corresponding W-shaped reflector of its element 1, proportional to the control, for example, the music signal. The surface at the point at which K is affected by the actuating element 4 of each t-grant reflecting element 1 begins to bend (deform), and differently depending on the value of the control signal, as a result

projected on the screen 12, changes its shape depending on the change in the nature of the control signal,

If the forming light reflector is located, for example, in a projection device (FIG. 3) and if light reflections element 1 is made in the form of, for example, n cylinders, raspoptichesky axis, in the absence of a musical signal on the screen 2 a multicolored mosaic pattern is observed, the structure of which is and

the intersection of the neighborhoods. The color light image changes due to the movement of the light filters 9 and the shaping Stencil 10, reflecting many times in the cylinders of the t-sided reflective element 1, constantly forms a striking intersection of the circles and the elements formed by their intersection are practically non-repetitive.

Each actuator 4 exerts a pressure proportional to the control signal, and the corresponding cylinder has a t-faceted reflector. Element 1. E As a result of the pressure exerted, the surface of each cylinder of the W-shaped reflecting element 1 at the point of contact with the actuating element 4 bends deforms) differently depending on the incoming signal, due to which each element of a multicolored mosaic the picture changes its shape and colored light halo. - its shape.

Thus, the dynamics of the light images created on the screen 12 by the shaping stencil 10 are organically combined with the dynamics of changes in the outlines of individual image elements and the dynamics of changes in the entire light pattern as a whole and the halo around it, which emphasizes the character of the accompanying musical composition.

If a t-sided reflecting element is a 1-n-sided prism, a multi-colored kaleidoscopic picture is observed on the screen, the structure of which consists of individual triangle elements, four, five, and so on.

You 4 kinematic nodes 3 installed in the hole 5 exert a pressure proportional to the musical signal on the face of the n-sided prism j of the m-sided reflecting element 1. The plane of the faces of the prism of the t-facet reflecting element 1 is bent (deformed), as a result

The sides of the individual elements of the image are Q in the inner diameter of the light projection tube 2. The parts of the outer surface of the t-facet reflector (of its element I, which are not subjected to elastic deformation, are glued to the inner surface of the light projection tube 2.

The dimensions (length) of the actuating element 4 should change depending on the configuration of the t-facet on screen 12, change their shape depending on the control music signal.

Thus, the changes in the shape of each individual image element are organically combined with the dynamics of the change in the texture of the pattern inside each individual element.
