Abstract

The invention relates to optical instrument making and allows extending the operational capabilities of projection devices for producing color synthesized images. In the device, each imaging holder 14 is placed between the reference 15 and the presser 16 glasses and is mounted for movement relative to the frame 10 in two mutually perpendicular directions and rotatably around the optical axis by means of movable carriages 11,12,13 associated with the respective drives. . The film holder 17 is also mounted for movement along the optical axis of inclination relative to it with the help of three screw pairs placed on frame 10. Running nuts 25 screw pairs are located in supports 24 fixed on frame 10, interact with screws 26 and are connected to each other by tape transfer 27. At the same time, each screw 26 is a threaded support that is rotatably mounted relative to the spindle nut 25 by means of a mechanism 30 associated with the drive. 4 il.

The invention relates to optical instrumentation, specifically to projection devices with a translucent screen for visual observation, followed by photographic recording of the image.

The aim of the invention is the expansion of operational capabilities.

Figure 1 shows the device, a general view; figure 2 - node snapshot with drives; Fig. 3 is a section A-A in Fig. 2 in Fig. 4 is an optical diagram of the instrument.

The device for producing color synthesized images (Fig. 1) consists of four illuminators 1, a block of snapshots consisting of a plate 2 and four nodes 3 snapshots, four objectives 4 with blocks of color 5 and neutral 6 light filters, a translucent screen 7 and a photo cassette 8, fixed-on housing 9.

The node of the snapshot holders (Figures 2 and 3) consists of a frame 10 on which movable carriages 11-13 m of snapshot holder 14 are located one above the other, on which a snapshot 17 is placed between the reference 15 and the presser 16 glasses. movable relative to frame 10 in two mutually perpendicular directions by mechanisms 18 and 19 from electric actuators 20 and 21, and with the possibility of turning around the optical axis by mechanism 22 from electric actuator 23. On frame 10 on bearing supports 24 are installed the same three running nuts 25, interacting with screws - threaded supports 26, on which the node 3 of the snapshots is mounted on the plate 2. All the running nuts 25 are connected to each other by a belt drive 27 with the possibility of their simultaneous rotation by means of the mechanism 28 from the electric drive 29 to move the picture 17 along the optical axis.

Each threaded support 26 is rotatably mounted by mechanisms 30 from actuators 31 to provide the necessary inclination of the image 17 relative to the optical axis.

The optical layout of the instrument (Fig. 4) contains a chain of identical projection channels. In each channel thereafter

The illuminator 1, the node 3 of the photo-holders, the lens 4 with a block of 5 color and 6 neutral light filters are carefully installed.

Illuminator 1 serves to uniformly illuminate the image 17 and contains a spherical reflector 32 (FIG. 4), a source 33 of light, a heat detector 34, a corrective light filter 35 and a four-color condenser 36. A wide-format picture 17 mounted between the reference and pressure glasses 15 and 16 of the holder 14, lens

4 projects to a common translucent screen 7. A block of 5 color filters is installed to receive on the screen

7 color images, and a unit of 6 neutral light filters is installed for a stepwise change in the luminous flux. For selective operation with separate projection channels and for the implementation of the required exposure value during photo registration, each lens 4 has a shutter 37 controlled by an electromagnetic actuator (not shown). The illuminated screen 7 consists of a lacquered lavsan film 38, placed between the supporting 39 and the presser 40 glasses.

The device works as follows.

The plate 2 (Fig. 1) with the 3-shot holders is moved, with each zone holder 14 (Fig. 2 and 3) having zone negatives positives) 17, after which the Pliois 2 is replaced to its fixed position. Then, illuminators 1 are turned on and images are combined on the translucent screen 7 by moving each 14 rib camera commander from the control panel. Next, the images of the negatives (positives) 17 are synthesized on screen 7 by using color blocks.

5 and neutral 6 light filters in each channel and decoding of the synthesized image of full widescreen images. The change in the condition of the colors of the objects in the synthesized image can be additionally made by adjusting the voltage on the sources of light 33 (Fig. 4) in the cat-channel. After the decoding process, the translucent screen 7 is removed, set, the photographic frame of the set 8 and the photographic recording of the synthesized image is performed. In the case of zooming, each image 17 installed in image holder 1A is moved along the optical axis using the mechanism 28 associated with the actuator 29, and the corresponding projection lens 4 is moved. When transforming images 17, the corresponding image is tilted relative to the optical axis by rotating the threaded support 26 by means of the mechanism 30 from the electric drive 31, associated with the corresponding threaded support.
