摘要： An optical signal processing method and an optical component (20) are provided. The optical component (20) may implement two completely symmetric optical paths. Insertion losses of the two optical paths do not vary as an input polarization state changes, and the two optical paths have a same delay, thereby implementing polarization independence of the optical component (20). Further, two optical signals can be processed by using only one polarization-sensitive optical component (21). On one hand, costs of a user are reduced. On the other hand, the optical component (20) is always in presence of light. Therefore, a controller can control a status of the polarization-independent optical component (21).

摘要： A detection and communication system, a control apparatus, and a detection system are disclosed, and may be applied to fields such as augmented reality AR, virtual reality VR, or vehicle-road synergy. The detection and communication system includes: N radars, configured to: separately search for a target, and separately align with the target, where N is an integer greater than 1, K radars that are in the N radars and that align with the target are configured to communicate with the target, N-K radars other than the K radars are configured to track and point the target, and K is a positive integer less than N. The N radars separately align with the target, to help improve precision of alignment between the radar and the target. In addition, some of the N radars may communicate with the target. When more than one radar communicates with the target, this helps improve stability and reliability of communication between the radar and the target.

The first reference plane is aligned with the second reference plane, and the first alignment mark is aligned with the second alignment mark. A hybrid encapsulation manner is used for the optical module structure, so that encapsulation density of the optical module structure is increased, and channels of the optical module structure are increased when an area is the same, to support an optical interconnection for a large amount of data. In addition, a passive alignment manner that is convenient and quick is used for the optical module structure, so that an error caused by manual alignment is avoided, and alignment precision is relatively high.
