Abstract

The invention relates to an automatic three-lens switchover mechanism for a vehicle-mounted self-adapting optical imaging telescope and belongs to the technical field of optics. The mechanism solves the technical problems of complicated process, high cost, low rigidity, low transmission accuracy, inconvenience in operation, poor locking effect and influence on imaging quality of an optical system in the prior art. The automatic three-lens switchover mechanism comprises an angle encoder, a shaft system, a transmission mechanism and a locking mechanism, wherein the transmission mechanism is a moment motor; a rotor of the moment motor is in screw connection with a rotating shaft; a stator is in screw connection with a base; an unlocking linear motor is in screw connection with the base and is coaxial with a locking bolt; an unlocking pressure spring is located between the unlocking linear motor and the locking bolt; an unlocking photoelectric limit and a locking photoelectric limit are symmetrically connected onto the base of the unlocking linear motor; a limiting block sheet is located on an output shaft of the unlocking linear motor; the rotating shaft is sleeved with a code disk of the angle encoder; and a reading disk of the angle encoder is connected with the base via a connecting plate and a locking disc.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a three-mirror automatic switching mechanism for a vehicle-mounted adaptive optical imaging telescope. Background technique [0002] The meter-class vehicle-mounted adaptive optical imaging telescope includes the main imaging system and the zoom system on board. In order to realize the time-sharing imaging between the two systems, it is required that the three mirrors have a high-precision automatic switching function. At present, the main technology adopted at home and abroad is to drive the three mirrors to rotate through the turntable to realize the alignment of the turning optical axis with different imaging systems, and lock the turntable to ensure the stability of the image plane during work. [0003] The three-mirror automatic switching mechanism includes shafting, transmission mechanism, angle sensor and locking mechanism. The 1.2-meter self-adaptive telescop...
