AI Technical Summary
In existing technologies, the optical path of the power balance coil pose monitoring scheme is complex, the alignment is demanding, and the space occupied is large, making it difficult to integrate into a miniaturized and portable desktop power balance. The PSD scheme is prone to beam lock-up, signal interruption, and weak resistance to background light interference, which cannot meet the requirements of high-precision pose monitoring.
By collecting vertical and horizontal monitoring signals from the target power balance, the tilt angle and lateral displacement of the coil are determined respectively. The signals are obtained using a triangular target and a corner cone lens frame target, and then combined with a spectral confocal displacement sensor for real-time calculation, so as to achieve accurate monitoring of the coil's pose information.
It achieves high-precision coil pose monitoring with strong anti-interference ability, is suitable for miniaturized integration, and solves problems such as complex optical path, strict alignment and large space occupation, thus meeting the needs of high-precision pose monitoring.
