Abstract A phase compensation method for 1-bit phase quantized transmitarray is discussed. Using the tiled architecture of the transmitarray, the position of each unit cell is changed along the optical axis of the transmitarray. The spatial displacement allows changing the resulting phase distribution along the transmitarray aperture. Analytical calculations were performed to demonstrate the performance of the transmitarray radiation pattern.

The multi-joint measuring arm’s measurement accuracy is associated with the measuring pose configuration. As the feature of the multi-joints arm with the adjacent joint orthogonal design, the triangle-based representation of measuring arm configuration was derived. Then measuring arm pose configuration simplified representation was presented. Based on the simplified representation, a polynomial model of comprehensive error compensation was proposed, and the calibration algorithm was derived.Tests confirmed the effectiveness of the method, which can effectively improve the single-point measurement accuracy.
