SU363064A1 - HIGH-SPEED CINCAMERA WITH CONTINUOUS FILM MOVEMENT - Google Patents

Description

The invention relates to film photographic.

Known BbiooKocKOipocTHbie kiaokamera with non-reliant motion of the film, containing in the housing the main and additional optical channels, a tape-proof drum. With holes and mi (sighting and focusing device.

In the proposed cinema.camera, the recording of the process under study and the oscillogram of the process meters corresponding to this section are synchronously recorded and the constriction is simplified thanks to TOiMy that the main optical axes of the main and additional channels are aligned and turned back at an angle of 180 °, they are also aligned with the main optical axis of the izirno-focusing device.

FIG. 1 schematic view showing the proposed camera, general view; in fig. 2 shows a section according to software A-A of FIG. one; in fig. 3 - an approximate location of the oocyte system on a 35-millimeter K | Inoflenka.

In the light-mounted housing (not shown) of the a-device there is a tape-toothed gear-drum 7 rewinding the film 2. With the Supporter-spool on the receiving one (not shown), and the rotating prismenny compensator 5 shifting the image which together with the shooting lens 4 forms the main optical channel. The toothed drum has a number of identical and evenly spaced radial holes 5, the number of which is equal to the number of film frames that can be located on the surface of the drum.

A rectangular deflecting prism 6 is mounted inside the toothed drum. Optically coupled to the deflecting prism 7 of the viewfinder of the camera, consisting of lenism 6 and 7, as well as the lens 8 and about the lens 9. On the long side of the prism 7 glued together with such a prism. my 10. These prisms, together with the lens II and prism 6, constitute an additional optical channel for removing the screen of the oscilloscope J2.

The image of the lens through the main optical channel (lens 4 and the Pvnsator 3} is built on the section of the film 2 lying on the gear drum /. At the same place, the oscilloscope screen 12. builds the rays 12. At the same time, the rays from the screen fall on the lens // go through prisms we are 10 and 7, then are deflected by 90 ° and along the main optical axis of the core of the optical channel through the aperture 5 in the drum / pass to the film 2 from the side of its substrate. The latter is a weak neutral light filter Om and 1 on the image quality oscillogram We no effect. Since the number of holes 5 of the drum 1 is equal to the number of film frames which may

.. placing its circumference, then when the drum rotates, each subsequent shot will have its own hole. The strips between the holes of the slit play the role of the obturator and in COOTBeTCPBHH with this in, the interframe oscillogram space will not be recorded.

Since the images of the object and the otstillo1 frame coincide, their visibility, development and control of the zooming are carried out using the ad-viewfinder viewfinder.

When the rays carrying both images are deflected 90 ° by the prism 6, fall on the prism 7, once again deflect, by 90 ° the face 13 common to the prisms 10 and 7, get into the objective 8 of the search engine. The image constructed by lens 8 (viewed through the ocular p 9.

The prism, 10, is not a strictly necessary element of the circuit and is used for leveling the optical path length of the rays in both halves of the additional optical channel. In addition, both the Yu and 7 monopters should be replaced with an ad-hoc mirror.

located along a common tran-prism 7 and 76.

To increase the luminosity of the additional

optical channel prism 10 and 7 during

surveys can be output “from the ray path.

Subject invention

1. High speed movie camera with continuous film movement, containing

the main and additional optical channels, a tape drum with apertures 1 and a video focusing device, characterized in that, for the purpose of simultaneous recording on each stretch of film

We study the oscillogram of process parameters, the main optical axes of the main and additional channels of the main and additional axes (placed at an angle of 180 °).

2. Kinoka | mera no. 1, characterized in that, with the aim of modifying genre, the main optical axes of the main and additional channels are aligned with the main optical axis of the sighting focusing device.
