OPTICAL-TELEVISION DEVICE FOR REMOTE VISUAL MONITORING Russian patent published in 2013 - IPC G02B23/24 A61B1/06 

FIELD: physics.

SUBSTANCE: device has an illuminator, lenses, a forming unit, transmitting units, a T-shaped unit, a sighting telescope and a video module. There is a power and control unit for operation of the device. The illuminator used is side and front optical caps made of stainless steel; the lenses are four-lens objective lenses with focal distance f'=20 mm or a lens made of radiation-resistant glass with focal distance f' equal to 40, 70 or 130 mm. The forming unit and the transmitting units transmit an intermediate image formed by the lens through the T-shaped unit to the photodetector of the video module, wherein the mirror is output from the light beam or through the sighting telescope onto the retina of the observer. The T-shaped unit is an optical-mechanical unit with a swivel mirror which is mounted on an axis of rotation at the centre of the unit with an angle between the axis of rotation of the mirror and the optical axis of an endoscope which is equal to 45 degrees, with possibility of fixing two positions which are set manually using a lever.

EFFECT: providing remote visual monitoring of process equipment in liquid and air media, in strong radiation fields.
