Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, it is a schematic diagram of the overall structure of a small-scale high-precision staring infrared photoelectric stable tracking platform provided by the present invention. The platform is composed of a pitch servo platform, a roll servo platform and a digital servo circuit 22 . The pitch servo platform is installed above the roll servo platform, and the digital servo circuit is installed under the roll servo platform. The three parts of the pitch servo platform, roll servo platform and digital servo circuit together form a complete "pitch axis + roll axis" Servo-stabilized platform.

[0025] Such as figure 1 As shown, the pitch servo platform includes a pitch axis 1, a pitch bearing 2, a pitch angle measuring code disc 3, a pitch drive motor, a pitch gyro 6, a pitch bracket 7 at the code disc end, and a pit...

Description

technical field [0001] The invention belongs to the technical field of a photoelectric stable tracking platform, and in particular relates to a small high-precision staring infrared photoelectric stable tracking platform that can be applied to photoelectric detection and infrared seekers. Background technique [0002] Optoelectronic platforms are widely used in search and tracking systems, photoelectric detection systems, seeker technology, etc. Optoelectronic platforms are key components of the above systems, which play a role in stabilizing optoelectronic loads, searching and tracking sight targets. The new generation of infrared detection system requires the photoelectric stable tracking platform to be small in size, high in precision and wide in tracking range. The frame structure of the traditional photoelectric platform adopts a three-frame or two-frame configuration, but the three-frame stable platform has a large volume, weight, and high cost. In the field of infrare...
