Abstract: Disclosed are a lidar, and a detection method for the lidar. The lidar includes a plurality of laser transceiver module groups, each configured to be integrated with at least one laser transmitting end and at least one laser receiving end, and a scanning module. The plurality of laser transceiver module groups are arranged in a distributed manner relative to the scanning module, and an at least partially stitched field of view of the lidar is formed by sub-fields of view correspondingly formed by the plurality of laser transceiver module groups. Further disclosed are a lidar and a manufacturing method for the lidar. The lidar includes a laser transmitting end, a laser receiving end, a scanning module and an isolation mechanism. A scanning component of the scanning module is constructed as a rotatable plate-shaped double-faceted mirror or a rotatable prism.

Abstract: A ternary polycrystalline material based on lead hafnate (PbHfO3) and having improved dielectric, piezoelectric, and/or thermal stability properties. The Pb(Hf,Ti)O3 based material can exhibit enhanced electromechanical coupling factors when compared to PZT based ceramics and can be used as high performance actuators, piezoelectric sensors and/or ultrasonic transducers. The ternary polycrystalline material can have a perovskite crystal structure with an ABO3 formula and can be characterized by a substitution of heterovalent acceptor and donor ions at A or B (Zr/Hf) sites.
