A ladar system has been patented, comprising a ladar transmitter, ladar receiver, and processor. The system operates in both ladar and optical communication modes, transmitting ladar pulses towards targets in a field of view and encoding data messages for optically communicating with devices. The ladar transmitter includes scannable mirrors for directing pulses, with different frequencies or wavelengths used for ladar and communication modes. The processor performs image analysis and object detection to locate devices, such as optical receivers on vehicles, enabling point-to-point communication between vehicles via ladar pulses.

Furthermore, the system can encode various data messages, including traffic data, ladar point cloud data, and text messages, in the ladar pulses using delays between pulses. A memory stores laser dosages delivered to different locations in the field of view, allowing the processor to control the ladar transmitter to avoid exceeding defined thresholds. The patented method involves transmitting ladar pulses for range measurements, determining device locations, and encoding data messages for optical communication. This innovative ladar system offers a versatile solution for point-to-point communication between vehicles, utilizing ladar technology for efficient data transmission and object detection in a field of view.
