Article Synopsis
- - This study introduces a precise method for measuring lens centering errors using power analysis and a specialized prism setup with subwavelength grating and reflection-centering systems.
- - The accuracy of the method is enhanced through the use of -1st-order rays at 5 mW and 650 nm, utilizing Snell's law and diffractive characteristics for testing optical axis errors.
- - The proposed technique achieves a fourfold improvement in resolution over traditional autocollimation-based systems, increasing sensitivity and lowering sensor requirements for measuring light direction and energy variations.
