This invention relates to an optical system for MEMS scanning lidar based on freeform surface optical power compensation and its design method. The system includes a laser emitting module, a compensation lens, a MEMS scanning mirror, a freeform surface mirror, a beam-splitting prism, and a single-point detector. The system is designed based on the established correspondence between the MEMS scanning angle, the incident position of the freeform surface mirror, the local radius of curvature, the local reflected optical power, and the refracted optical power of the compensation lens, combined with the freeform surface mirror and the compensation lens. The system has a simple structure and is easy to operate. By matching the optical power of the compensation lens and the freeform surface mirror, and combining this with the MEMS scanning process, it maintains a low divergence angle and stable echo reception capability even under large field-of-view scanning conditions. This improves the system's adaptability and imaging quality, meeting the imaging requirements of lidar. It is suitable for applications such as autonomous driving lidar, robot navigation, and 3D environmental perception.

This utility model discloses an electrical connection device for a relay base and its matching point detector, relating to the field of fire protection electrical connection technology. It includes a base and a detector mounted on the base. The detector has a plug with contacts, and the base has a guide plate. A connecting component is provided between the plug and the base to enhance the connection stability between them. The connecting component includes a connecting block located in the base. This utility model, by setting the connecting component, allows the connecting block to automatically engage with the plug's slot when it is inserted into the base, thus completing the limiting connection of the detector on the base. Compared to traditional plug-in methods, this method offers higher connection stability. Even if the metal contact deformation capacity decreases, the detector can still be firmly connected in the base, preventing loosening and detachment.

The invention provides a device, method, program, and recording medium for providing information about multiple recommended spots near a moving object, ensuring that the information is provided before the moving object reaches a branch point leading to the recommended spot.When a recommended spot extractor 130 extracts multiple recommended spots and a branch point detector 150 detects multiple branch points, a controller 180 prioritizes providing information for the recommended spot that is guided from the branch point, based on a shorter time from the current position of the moving object to the branch point. The controller 180 also determines an information provision timing, based on the time needed to reach the branch point and the time required to provide spot information of the recommended spot, ensuring that the provision of the information is completed by the time the moving object arrives at the branch point to the recommended spot.
