What is a good solution to make ultra clear and precise dot indication for special working occasions of Lidar ranging? A simple laser pointer or other visible laser device cannot be workable at all. Under operation of constant technical innovation of 980nm infrared laser diode tech and a qualified glass coated lens inside a durable metal housing tube, it is manufacturing into a professional dot measuring tool of a infrared laser diode module. It gets constant electric power source supply and proper connects with an external electric power source supply. Cooperated with night version device or equipment, being used as core laser light source for Lidar ranging, infrared dot laser alignment projects a narrow pulse of infrared laser light towards the target object. The receiving module captures the reflected light signal, and the time-of-flight (ToF) principle is used to calculate the round-trip time of the light signal, thereby accurately calculating the target distance.
980nm infrared laser diode module belongs to a near infrared laser device, owing to its invisible laser light emission, it should only be used as an accessory part. In conjunction with scanning mechanisms, such as galvanometers and MEMS micromirrors, the infrared laser dot scans the detection area along a preset trajectory, achieving 3D modeling of the spatial environment and multi-target distance measurement, providing distance data support for the radar system. Being made with a qualified glass coated lens and adjustable focus optic lens in front of laser beam aperture, infrared dot laser alignment is working well with highly powerful and high photoelectric ability infrared laser light source emission. After conversion of strong light spot focusing and narrow pulse width, it enables accurate capture of reflected signals. Ranging errors can be controlled at the centimeter or even millimeter level, meeting high-precision ranging requirements.
When 980nm infrared laser diode module gets constant electric power source supply, 980nm infrared light can avoid visible light and common interference, is not easily affected by sunlight or ambient light, and can still stably output distance data under complex lighting conditions. Owing to its quick reaching and good direction infrared laser dot projection, it just takes low energy consumption, adaptable to the performance requirements of various ranging fields. Featured by its small size and light weight, this infrared alignment laser can be easily integrated into the overall Lidar system. It meets the requirements for miniaturization and lightweight design, and also has a long service life, reducing radar system maintenance costs.
