Abstract

CONVERGENCE OF OPTICAL DEVICE STEREOTELEVIZIONNOY RAY CAMERA WITH ONE transmission tube, comprising a control unit having an input connected to the output clock, the first and second drive units associated respectively with the first and second movable mirrors arranged at equal distances from one optical axis. II ----- a lens located in front of the optical input of the transmitting tube, the first and second movable mirrors being optically connected to the third and fourth mirrors located in front of the lens, and the flat and third mirrors are perpendicular and set at an angle of 45 &;deg; to the optical axis of the lens, characterized in that, in order to increase the depth resolution in the entire convergence range of optical rays, the fifth and sixth mirrors are introduced, the planes of which are parallel to the plane of the fourth mirror, made with controllable transparency and connected to the output of the control unit , while the fifth mirror is located on the same axis between the second and third movable mirrors.

Description

CO CD
The invention relates primarily to television technology, namely, stereo television and can be used in stereocinematography.
A device for converging optical rays of a stereo-television camera with a single transmitting tube is known, which contains four mirrors, three of which with full reflection, the fourth translucent, lens optical elements and light-valve elements, two mirrors with full reflection are spaced apart for a certain distance, the third mirror with full reflection and the fourth semi-mirror mirror is placed between the first and second parallel to the first and second, respectively, and at an angle of 90 to one another S lens and light-valve element times bridges between the first and the third and between the second and the fourth mirrors respectively 1 X
The disadvantage of this device is low sensitivity, limited by the loss of the light information of the fourth mirror, which is made translucent.
The closest in technical essence to the present invention is a device for converging optical stereo television cameras with one Transmitting tube, containing a control unit whose input is connected to the output of the synchro-generator, the first and second drive units, respectively, connected to the first and second movable mirrors located equal distances not from one optical axis, a lens located in front of the optical input of the transmitting tube, the first and second movable mirrors being optically coupled to the third and a quarter - mirrors S placed before the lens, and the plane of the third and fourth mirrors are perpendicular to and installed at an angle 45 to the optical axis of the lens 2 J,
However, the known device gives an error in the angles of rotation of the mirrors, which leads to a decrease in the depth resolution of the stereoscopic television camera,
The purpose of the invention is to improve the glare resolution over the entire range of convergence of optical rays.
To achieve the goal, the optical beam convergence device of a stereo-television camera with one transmitting tube, containing a control unit 2, the input of which is connected to the output of the synchro-generator, the first and second drive units, respectively connected with the first and second movable mirrors, are located (on equal distances x from one optical axis, the lens located in front of the optical input of the transmitting tube, the first and second moving, the optical mirrors are connected to the third and fourth, mirrors located The third and fourth mirrors are perpendicular and set at an angle of 45 to the optical axis of the lens, the fifth and sixth mirrors are introduced, the planes of which are parallel to the plane of the fourth mirror, made with controlled transparency and connected to the output 2, house control unit, while
The fifth mirror is located on the same axis between the second and third movable mirrors.
The drawing shows an optoelectrically structural diagram of a device for converging optical rays of a stereo-television camera with one transmission tube.
The device comprises a transducer tube 1, a lens 2, a first sublimated mirror 3 and a second movable mirror 4, made rotatable and installed at equal distances from the optical axis of the lens 2, the third mirror 5 and the fourth mirror 6s mounted in front of the lens 2 5 the fourth mirror 6, located closer to the lens 2, the planes of the third mirror 5 and the fourth mirror 6 are perpendicular and the antenna is at an angle of 45 ° to the optical axis of the object 2, the fourth mirror 6 is made with controlled transparency, electrically connected to control block 7 output, input
0 which is connected to the output of the half frame pulses of the synchronizing generator 8, the fifth mirror 9 and the sixth mirror 10, the planes of which are installed parallel to the plane of the fourth mirror of that mirror 6, the first and second drive apples 11 and 12 are kinematically connected with the lens 2, the first moving mirror 3 and second under
