FMCW LiDAR:
FMCW lidar boasts unique capabilities for accurately detecting the speed of moving objects and possessing comprehensive, three-dimensional perception of the surrounding environment. From target recognition, instantaneous response, and trajectory prediction in intelligent driving and robotics to high-precision detection and all-weather anti-interference capabilities in intelligent transportation and smart industry, and even expanding into new areas such as smart homes, agricultural machinery, and interactive entertainment, FMCW lidar demonstrates its superior performance and widespread application advantages.
Laser wind measurement:
Based on the Doppler effect, the laser wind measurement system uses the interaction between laser and aerosols or molecules in the atmosphere to measure wind speed and direction. It plays an irreplaceable role in scenarios such as meteorological disaster prevention and mitigation, three-dimensional environmental monitoring, smart wind power operation and maintenance, aviation safety, and low-altitude economic security.
Medical beauty:
1550nm laser therapy is a new technology for skin rejuvenation, inducing collagen remodeling through controlled thermal effects in the dermis. It also produces a thermal effect within the dermis, inhibiting sebaceous gland secretion, promoting skin repair and metabolic processes, and reducing oil and bacteria in pores while maintaining normal pore conditions. This thermal effect increases collagen in the skin, restoring skin elasticity, enhancing the smoothness and refinement of the skin’s texture, and shrinking abnormally dilated pores.
