Types of rangefinders
Introduction: As an optical rangefinder, it has been widely used in various fields. Rangefinders can be divided into ultrasonic rangefinders, infrared rangefinders and laser rangefinders. The latter two rangefinders are no longer in production due to limitations in accuracy and distance. At present, the infrared rangefinder refers to the laser infrared laser rangefinder, that is, laser ranging. Infrared rangefinder - an instrument that uses modulated white external light for optical ranging, with a range of usually 1-5 kilometers.
