Description

 It is known that projection devices are widely used, including in the educational process of educational institutions. The screen images of the object obtained with their help are characterized by the following levels of visibility: if the image is displayed discretely (for example, by replacing fragments, transparencies, frames, etc.) - it is of an average level of visibility; if the image demonstrates a continuous process (for example, like in a movie) - it has the highest level of visibility. An image observed in a static state refers to a lower level of visibility.

 In the practice of training, all these types of displays are used.

 However, especially often there is a need for dynamic (continuous) displays of the studied objects.

 In the manual (Kondyurin V.I., Tyutyunik E.G. Technical means of propaganda in the army and navy. - 3rd ed., Revised. And additional. - M .: Military Publishing House, 1987, p. 352) a description is given technical means of propaganda with the characteristics of projection equipment, having become acquainted with which you come to the conclusion that only by showing filmstrips and films can you get images of the state of objects of the highest level of visibility, but they are not used in all types of classes and have difficulties in repeating displays of individual fragments of the state of objects and their work about based on a given "canvas", there is no freedom in the dynamism of displaying images of changes in the state of an object.

 A prototype of the invention is a mounting-projection device in which an image projection method is applied that gives (certain) freedom in the dynamism of displaying an increased image quality of a variable state of an object obtained by converting images of individual fragments into a single compositional portrait. The device comprises a light source, a lighting system, transparent carriers of image fragments (transparencies), located between fiber-optic plates that are fixed one after another in their plane. The image carriers are moved in the plane of their installation and the total image of the changing states of the object (portrait) is projected onto the screen, this is the essence of the image projection method.

 Obviously, the expansion of the dynamic demonstration capabilities of the method depends on the presence of transparent carriers of image fragments. Just their quantitative growth is unacceptable, as this leads to an unjustified increase in size and complicate the design of the device. Therefore, an increase in the number of transparent carriers of image fragments is achieved by installing several carriers in a combined plane or, more precisely, by dividing the transparent carrier of the image fragment into several carriers that carry its elements.

 Another acceptable way to quantitatively increase the carriers of a fragment is to use fiber optic plates as carriers of a fragment of images, for this they are structurally provided with freedom of movement in their plane and fragments of the image of an object are applied to their end surfaces, for example, manually, with easily removable dyes.

 Thus, the fragmentation of the device is doubled.

 Now, with the use of all fiber-optic plates and not all transparent carriers of image fragments, the quality of the screen image of the state of the object spontaneously increases. By using only fiber-optic plates, the highest quality of the screen image of the state of the object is achieved.

 In order to ensure simultaneous interconnected movement of fiber optic plates and transparent carriers of image fragments, fixators are installed between them.

 The method is illustrated in figures 1-4.

 In a device that implements the proposed method and contains a light source 1 and a lighting system 2, transparent carriers of image fragments 3-7 and fiber optic plates 9-14 are shown beyond the luminous flux of the device, which indicates the possibility of their displacement without going beyond it in addition, the absence of the 8th transparent fragment carrier indicates an increased quality of the screen image it receives.

 Figure 2-4 shows the involved transparent media 3-5 and fiber optic plates 9-13 with their image fragments, as well as screen images 16 (a, b, c) of the state of the object.

 In the proposed method for projecting images, fiber-optic plates 9-14, which are fixedly mounted in their plane, are provided with plane movement and removal (dismantling) for applying onto the end surfaces of them, for example, manually required image fragments with easily removable dyes. This thereby doubles the fragmentation of the method, in addition, to ensure simultaneous interconnected movement of the media 3-8 and plates 9-14 between them are installed, for example, mechanical clamps 17.

 Figure 2-4 shows carriers of image fragments 3, 4, 5 and fiber optic plates 9-13 with their fragments having: 5 - a moving coordinate system XOY, 11 - a fixed XOY, 12 - a parabola, in addition, screen displays images of the state of the object 16 (a, b, c).

 Fragments of points 3, 9, 4 and 5, 11 in the initial position are aligned with each other so that on the screen (see 16, a) there is an image of one point and XOY, as well as parallel lines from fragments 10 and 13. Then, changing the position 3, 9, 4, for example, manually (fastened together by latches 17), the set point motion relative to XOY is observed on the screen. Then, having removed the latches 17 and shifted between each other 3, 9, 4 on the screen (see 16, b), a system of three points is observed having the possibility of both joint and individual movement relative to XOY and XOY. At 16, in shows one of the many types of screen images of the state of a continuously changing object.

 The effectiveness of the application of the proposed method in projection instrumentation, which increases the fragmentation of devices and improves the quality of screen images by replacing transparent carriers of fragments with fiber optic plates, is obvious.
