LASER WARNING SYSTEM AND METHOD THEREOF

摘要

PURPOSE: Laser alarming device and method are provided to increase the reliability on the accuracy of the arrival angle of a laser signal by excluding a signal which distorts the incident direction of the laser signal. CONSTITUTION: A laser alarming device comprises a sensor module(10), a signal processing unit and a control module. The sensor module comprises a main detector(11) and a secondary detector(12). The main detector detects a laser signal within a view field range. The secondary detector is arranged around the main detector to detect a laser signal out of the view field range. The signal processing unit processes the laser signal detected by the sensor module. The control module receives the laser signal processed by the signal processing unit. The control module determines and alarms whether the incident laser signal is within the view field range.
