AERIAL CAMERA Russian patent published in 2017 - IPC G03B37/00 G01C11/02 

FIELD: physics.

SUBSTANCE: claimed aerial camera contains a mirror system along the beam in the body of the aerial camera, a focusing lens is placed at an angle to its optical axis, and in the additional housing there is a receiver of optical radiation, the photoreceptor zone of which is aligned with the plane of the best image of the focusing lens. The mirror system is mounted rotatable about the optical axis of the focusing lens with the help of a mirror system drive. The additional housing is mounted with the possibility of displacement with respect to the center of mass by means of drives, all drives are equipped with torque motors, the input of each torque motor is connected to the outputs of the drive control unit; on the axis of the rotor of each torque motor, a corresponding uniaxial angular velocity meter is fixed, whose outputs are connected with the corresponding inputs block of the drive control system. The mirror system is made in the form of a mirror afocal nozzle, the optical axis of which is perpendicular to the survey surface, for which the mirror system is rigidly fixed in the movable housing, and the movable housing is pivotally mounted with the help of a mirror system drive. The focusing lens is installed in an additional housing with an optical connection between the mirror afocal nozzle. The additional housing is rigidly fixed in the body of the aerial camera, and the focusing lens is made of a two-mirror. In the plane of the best image of the focusing lens, a second radiation receiver is added. Switching between the radiation receivers is accomplished by rotating around the optical axis a rotary inclined mirror located between the focusing lens and the radiation receivers. And the body of the aerial camera is rotatable with respect to the center of mass of the aerial camera due to the pitch change compensation drive and the image shift compensation drive, the drive control unit is configured as a navigation information processing unit.

EFFECT: ability to produce high-speed wide-angle and high-resolution narrow-angle imagery, the ability to shoot at high speeds and small altitudes of the carrier of an aerial camera, reduce the length of an aerial camera and improve the quality of images.
