Triple parabolic cone wheel: a driving structure for the rapid panoramic tracking imaging system

Area of Science:

• Optics and optical devices
• Mechanical engineering
• Infrared imaging technology

Background:

• Rotating staring panoramic imaging systems face challenges with low image data refresh rates, hindering practical applications.
• Existing systems typically operate at refresh rates of 0.5-1 Hz, which is insufficient for dynamic scenarios.

Purpose of the Study:

• To introduce an innovative driving mechanism, the triple parabolic cone wheel (TPCW), for panoramic infrared imaging.
• To enhance the image data refresh rate of panoramic imaging systems.

Main Methods:

• Designed and optimized the triple parabolic cone wheel (TPCW) mechanism.
• Incorporated three convex segments into the conical surface grooves of the cam mechanism.
• Utilized parabolic grooves to convert uniform rotation into variable linear mirror motion for driving multiple mirrors.

Main Results:

• The TPCW enables simultaneous driving of five mirrors with distinct motion patterns and speeds.
• Achieved a linear mirror movement, eliminating image rotation issues.
• Significantly increased the panoramic refresh rate to at least 3 Hz, a substantial improvement over existing systems.

Conclusions:

• The TPCW is an effective solution for improving the refresh rate of panoramic infrared imaging systems.
• The optimized cam mechanism design allows for precise control over multi-view mirror movement.
• This innovation addresses the practicality limitations of rotating staring panoramic imaging systems.
