In the field of optical experiments and lidar development, the demand for precise synchronous control of ranging equipment is becoming increasingly prominent. The erbium glass laser rangefinder has become a popular choice for related research due to its eye-safe characteristics and high-precision ranging capabilities. The existence of the external trigger interface provides key support for its application in complex experimental scenarios.
In optical experiments, the external trigger interface enables the erbium glass laser rangefinder to achieve precise synchronization with other optical devices. For example, in the process of studying the interaction between light and matter, researchers often need to simultaneously control the laser emission, detector signal acquisition, and ranging action of the rangefinder. Through the external trigger interface, the rangefinder can establish a time synchronization mechanism with laser light sources, spectrometers and other equipment. When the laser light source emits a laser of a specific wavelength to illuminate the sample, the rangefinder starts the ranging function at the moment of receiving the external trigger signal, and accurately records the time from the laser emission to the reflection and return of the target. This synchronization operation not only improves the accuracy of experimental data, but also helps researchers to more deeply analyze the propagation characteristics of light in the medium, the surface characteristics of the target object, etc. At the same time, in the multi-device joint experiment, the external trigger interface avoids the time error caused by manual operation, ensures the high repeatability of the experimental process, and provides a strong guarantee for the verification of optical theory and the discovery of new phenomena.
In the process of laser radar research and development, the role of the external trigger interface is also indispensable. The laser radar system usually needs to work with other sensors or control systems to achieve accurate perception in complex environments. For example, in the laser radar research and development of self-driving cars, the vehicle's motion state and the image information collected by the camera need to be fused with the laser ranging data. Through the external trigger interface, the erbium glass laser rangefinder can be synchronized with the vehicle's motion control system, camera and other equipment. When the vehicle drives to a specific position or the camera detects a target object, the motion control system or camera sends a trigger signal to the rangefinder, and the rangefinder immediately performs the ranging operation. This synchronization mechanism enables the laser radar to obtain accurate distance information of the vehicle's surrounding environment in real time, and match it with the image data collected by the camera in space and time, thereby providing more accurate and comprehensive environmental perception data for autonomous driving decisions. In addition, during the performance test and calibration of the laser radar, the external trigger interface also facilitates the collaborative work of the test equipment and the rangefinder to ensure the reliability of the test results.
From the perspective of technical implementation, the external trigger interface of the erbium glass laser rangefinder usually adopts a standard level signal or pulse signal trigger mode. Researchers can flexibly set the parameters of the trigger signal, such as the trigger delay time, the polarity of the trigger signal, etc., according to the experimental or R&D requirements. This flexibility enables the rangefinder to adapt to various complex experimental scenarios and R&D needs. At the same time, the design of the external trigger interface also fully considers the compatibility and scalability of the equipment, which is convenient for integration with other devices.
The external trigger interface of the erbium glass laser rangefinder plays an important role in optical experiments and laser radar research and development. It not only realizes the precise synchronization of the rangefinder and other equipment, improves the accuracy of experimental data and R&D efficiency, but also provides strong support for technological innovation and development in related fields. With the continuous advancement of optical experiments and laser radar technology, the functions and applications of the external trigger interface will continue to expand and deepen.
