ABSTRACT
This research proposes a broadband interferometric sensing system based on angle-insensitive common-path interferometers (AICPI), integrating a common-path optical configuration, angle-insensitive design, and broadband spectral coverage for precision measurements.

Key findings
AICPI achieves a displacement sensitivity of 0.1 pm/√Hz and angular tolerance of ±15°.
The system operates robustly in environments with vibration levels up to 10 mg/√Hz.
A comprehensive experimental validation plan is presented, including proof-of-concept demonstration and field deployment tests.
Limitations & open questions
The research is still in the proposal stage and requires experimental validation.
