Abstract

With the problem of small field of view, high precision and difficulty in alignment for portable laser communication, the method and device based on measuring field of view in portable laser communication are designed and proposed. By calculating the link energy under the specified communication distance, the energy range of extensible field of view can be obtained. A high precision measuring device is designed. The actual test was carried out. The result shows that the receiving field of view for portable laser communication is 0.63mard under the condition of 1km communication distance and the sensitivity of detector -30dBm. The field of view for portable laser communication can be accurately measured by the test method and device. The test device can extend the measuring range of small field of view in different fields.
