DEVICE FOR CIRCULAR SCANNING Russian patent published in 2009 - IPC G02B26/10 

FIELD: physics; optics.

SUBSTANCE: present invention relates to optical systems for scanning location and detecting objects. The device comprises a first mechanical transmission, an objective, an actuator kinematically linked through a second mechanical transmission to an image reversal unit and connected to the first output of the control unit, the second output and the first input of which are respectively connected to the input and output of multiple unit photosensitive device, and the third input connected to the output of the first position sensor. The device also has a swivel mirror and a position sensor. The swivel mirror is at an angle to the source of video signal and the optical axis of the objective, located between the swivel mirror and the image reversal unit, comprising a first, second and third mirrors, rigidly fixed in a rotating housing such that, the second mirror is parallel the axis of rotation of the housing of the image reversal unit. The first and third mirrors are at equal angles to the axis of rotation of the housing and to the second mirror. The line of intersection of the planes of the first and third mirrors is parallel the second mirror and is perpendicular the axis of rotation of the housing, passing through the centre of the first and second mirrors and coinciding with the axis of rotation of the first mirror and the principal optical axis of the objective. The outputs of the first and second position sensors are connected to the third and fourth inputs of the control unit, and the inputs are kinematically linked, respectively, to the housing of the image reversal unit and the swivel mirror, which is kinematically linked to the actuator through the first mechanical transmission. The first and second mechanical transmissions have a mutual transmission ratio of minus 2:1.

EFFECT: design of a device for efficient circular scanning.
