Abstract
Assessment of the influence of the manufacturing quality of a reflective coating on the angular distribution function of the reflected radiation intensity of laser signaling systems
Highlights
Promising automatic systems for protecting objects and perimeters of the area from all kinds of intruders are being developed based on the use of laser alarm systems [1,2,3,4,5,6,7]
This is due to the advantages of laser systems: the absence of physical and electronic contacts between the components, the accuracy of laser devices; light weight and small dimensions of lasers; high noise immunity and ease of installation and alignment of laser devices [1]
Laser alarm systems usually consist of a transmitter and receiver, which are located in a line of sight
Summary
Promising automatic systems for protecting objects and perimeters of the area from all kinds of intruders are being developed based on the use of laser alarm systems [1,2,3,4,5,6,7]. Laser alarm systems usually consist of a transmitter and receiver, which are located in a line of sight. The main disadvantage is false alarms in difficult weather conditions, which reduce the transparency of the environment (eg fog, rain, snow). In this case, the reliability of laser alarm systems can be ensured by using multiple excess of the laser radiation energy over the minimum threshold value necessary for the system to operate
