Dynamic Optical Alignment Method for AIMS

The Accurate Infrared Solar Magnetic Field Measurement System (AIMS) is a mid-infrared telescope designed for high-precision solar magnetic field observations. Due to its open-truss structure and off-axis optical configuration, the system is prone to gravityinduced misalignment between the primary and secondary mirro...

On-site optical wavefront testing and control for the AIMS solar telescope

The Accurate Infrared Magnetic Measurement System (AIMS) solar telescope is the world’s frst mid-infrared observational system dedicated to high precision measurements of solar magnetic felds and independently developed in China. The large number of optical components, multiple intermediate focal planes, and the long...

Focal length measurement of large-aperture optical systems based on defocus wavefront sensing.

We present a method for measuring the focal length of large-aperture optical systems based on defocus wavefront sensing. A 4D dynamic interferometer acquires Zernike defocus coefficients at different axial positions, from which the focal length is derived via a simplified expression. The method is validated on three op...
