Lidar modules have become integral components in various modern technologies, enabling precise distance measurement and environmental mapping through laser-based sensing. These modules operate by emitting laser pulses and measuring the time it takes for the light to reflect off objects and return to the sensor. This data is then processed to generate detailed three-dimensional representations of surroundings, making lidar essential for applications ranging from autonomous vehicles to industrial automation. The core of a lidar module typically includes a laser emitter, a scanner or beam-steering mechanism, and a photodetector. Advanced modules may incorporate solid-state designs, which eliminate moving parts for enhanced durability and reliability. In automotive contexts, lidar modules help self-driving cars detect obstacles, pedestrians, and other vehicles with high accuracy, even in low-light conditions. Beyond transportation, lidar is used in robotics for navigation, in agriculture for crop monitoring, and in surveying for topographic mapping. The evolution of lidar technology has led to smaller, more cost-effective modules, broadening their adoption across consumer electronics and smart devices. However, challenges such as interference from sunlight or adverse weather conditions persist, driving ongoing research into improved signal processing and multi-sensor fusion. As industries continue to prioritize automation and data-driven decision-making, lidar modules are poised to play a pivotal role in shaping future innovations, offering unparalleled precision in spatial awareness and object detection.
