Field of the Invention

The present invention relates to a laser warning system which can be mounted on wearable equipment or on a vehicle or a fixed structure and which ensures the safety of drivers and pedestrians by means of the warnings it gives.

State of the Art

Today, various developments are taking place in the automotive sector in parallel with the development of technology. The most important of these developments is the introduction of vehicles using electric motors instead of internal combustion engines. In addition to the advantages of the process in question, electric vehicles have disadvantages that may arise from their quiet operation and fast travel.

When walking on foot on streets and urban areas, one of the most important aids to making a decision to cross a road is the sound of approaching cars and car engines. Therefore, the increasing use of electric and autonomous vehicles and their silent operation can lead to accidents or security weaknesses for pedestrians, cyclists or visually impaired people.

In the current state of the art, the use of laser marking, laser ranging and aerial vehicles is increasing. The only defense against these threats is laser detection and laser warning systems. Today, there are systems that can detect and identify laser threats directed at them within a short response time and with high precision, and mobilize countermeasure systems however, these systems cannot be used by personnel carriers and combat vehicles, control stations, buildings and other vehicles due to their high cost and system integration problems. The disadvantages of existing systems are that they are not cheap, lightweight, man-portable and easy to install.

In addition, the high rate of false alarms in laser warning systems is among the disadvantages of systems in the state of the art. Special circuit and system designs are required to prevent errors and noise in these systems. Although this increases labor and cost, it does not reduce the false alarm rate to the desired levels.

The invention with publication number US9448107B2, resulting from technical research, relates to a method and apparatus used to detect the laser in a laser warning receiver. The above-mentioned apparatus is said to combine a panoramic lens assembly with a laser detection focal plane, and the laser light is refracted in the panoramic lens. In the above- mentioned invention, the refracted laser light is collected by a large number of sensors to determine the intensity corresponding to the laser light, and then the combination of the panoramic lens and the laser detection focal plane is configured to provide a low-cost laser warning for ground-based situational awareness.

As mentioned, the invention relates to a method and apparatus for detecting a laser in a laser warning receiver, but does not mention a structure that can provide a solution to the disadvantages mentioned above.

As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.

Aim of the Invention

The invention aims to provide a structure having different technical features which brings a new development in this field different from the embodiments used in the state of the art and to solve the above-mentioned disadvantages.

The main aim of the present invention is to reveal a laser warning system which can be mounted on wearable equipment or on a vehicle or a fixed structure and which ensures the safety of drivers and pedestrians by means of the warnings it gives.

Another aim of the present invention is to provide laser threat detection with a minimum number of sensors, preferably with a viewing angle width of more than 90 degrees.

Another aim of the present invention is to provide more accurate detection sensitivity with less false alarm rate by using lenses and/or mirrors and/or beam collectors, separating the incoming laser beams according to their wavelengths, filtering out the noise-generating beams, thus reducing the size of the system while not reducing the field of view and spectral scanning and increasing the detection rate in the revealed laser warning system.

Another aim of the present invention is to prevent false warnings by preventing noise by means of PCB (Printed Circuit Board) design in accordance with EMI (electromagnetic interference) and EMC (Electromagnetic Compatibility / electromagnetic compatibility) standards realized in the laser warning system.

Another aim of the present invention is to minimize the number of false alarms by detecting the wavelengths of laser threats preferably with high accuracy by means of special photodiodes operating at certain wavelengths through the laser warning system.

Another object of the invention is to provide a compact laser warning system, preferably weighing less than 5 kilograms, and to remain operational for a minimum of 24 hours without the need for recharging by means of lithium-ion rechargeable batteries.

In order to fulfil the abovementioned aims, the invention is laser warning system characterized in that, it comprises the following;

30 • oval lens, which is connected to the laser warning system box and increases the viewing angle of the photodiode by focusing the emitted laser beams at one point,

• electronic card which is connected to the laser warning system box and enables the signals obtained by means of said photodiode (3) to be sent to the

35 electronic control unit via the communication unit and to give a warning to the user via the buzzer and/or vibration sensor,

• photodiode, which is connected to said oval lens and detects the emitted laser light and generates signals at different voltage levels according to the

40 intensity of said laser light. In a preferred embodiment of the invention, the viewing angle of said photodiode is more than 90 degrees.

The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

Detailed Description of the Invention

In this detailed description, the preferred embodiments of the invention are described only for clarifying the subject matter in a manner such that no limiting effect is created.

The present invention relates to a laser warning system (1) which can be mounted on wearable equipment or on a vehicle or a fixed structure and which ensures the safety of drivers and pedestrians by means of the warnings it gives.

The laser warning system (1), which is the subject of the invention, comprises the laser warning system box (2), photodiode (3), oval lens (4), electronic card (5) and buzzer (6), as seen in figure 1.

The laser warning system (1) comprises photodiode (3), which is connected to said oval lens (4) and detects the emitted laser light and generates signals at different voltage levels according to the intensity of said laser light. Said oval lens (4) is connected to the laser warning system box (2) and increases the viewing angle of the photodiode (3) by focusing the emitted laser beams at one point. Said oval lens (4) may preferably be lens and/or mirror and/or beam collector. Signals connected to said laser warning system box (2) and obtained by said photodiode (3) are sent to the electronic control unit via the communication unit. The electronic card (5) provides a warning to the user via buzzer (6) and/or vibration sensor according to the value of these signals. The buzzer (6) is located inside the laser warning system box (2) and is therefore not visible. This is why buzzer (6) is shown in figure 1 with a dashed line.

Said laser warning system box (2) is preferably 40x40x40 cm in size for easy transportation. In the laser warning system (1), the width of the field of view of said photodiode (4) is preferably more than 90 degrees, while in the laser warning system of the state of the art, the accuracy of the threat position is approximately 15 degrees. In this way, all kinds of laser threats are detected with the minimum number of sensors possible.
