Abstract
A kind of intelligence laser protection mirror, basic structure are coated with one layer of TiO comprising one1‑xNxThe substrate of film is coated with one layer of VO on substrate2Film, in VO2It is coated with protective film outside film.When strong laser irradiation, due to TiOxN1‑xFilm (2) absorbs larger, temperature increases rapidly after absorbing laser energy, and the phase transition temperature for reaching the vanadium dioxide film layer (3) on its surface is undergone phase transition, and optical transmittance mutates, from start it is highly transmissive become high reflection, avoid photodetector from being damaged.Due to VO2Film layer (3) is easy the performance deterioration due to oxidation etc. in air, so in VO2Thin-film surface prepares protective layer (4) again.The intelligence laser protection mirror may be mounted on photodetector, the automatic reflection light laser in Irradiation of High, protect photodetector.
Description
Technical field
It is related that the invention belongs to photoelectric field, especially laser protections.
Technical background
Progress with laser technology and maturation are more using manufactured blinding laser weapons the characteristics of laser high intensity
State equips our troops, to interfere and destroy enemy's optical system.In photoelectronic warfare and Reconnaissance Equipment, photodetector is most to close
One of key member, it is the important means for obtaining information, is the change systems such as guided missile, satellite " eyes ", is most weak and most
It is vulnerable to one of the component of attack, the generally also target of attack of enemy first.Enemy is strong using blinding laser weapons transmitting
After laser enters detector via optical receiver antenna, our detector can be made to be interfered, suppress, be saturated, even burn, i.e.,
Photodetector blinding loses function, and moment causes observation instrument to fail, tracking and guidance system is out of control, nosefuze failure,
To be out of action.It can be seen that with the rapid development and application of blinding laser weapons, suffered by military optical system
It threatens increasing, how effectively to carry out lasing safety, protection photodetector becomes unavoidable important in modern war
Project.
The present invention proposes a kind of intelligent laser protection mirror, may be mounted on photodetector, in Irradiation of High
Photodetector is protected in automatic reflection light laser.
Invention content
The object of the present invention is to provide a kind of intelligent laser protection film, basic structure is coated with one layer comprising one
TiO1-xNxThe substrate of film is coated with one layer of VO on substrate2Film, in VO2It is coated with protective film outside film.
Description of the drawings
Fig. 1 Intelligent Laser protective glasses schematic diagrames
Specific implementation mode：
See attached drawing 1, specific implementation step is as follows：
1, TiO is plated on substrate (1) surfacexN1-xFilm layer (2)；
2, in TiOxN1-xFilm surface plates VO2Film layer (3)；
3, in VO2Thin-film surface protective film coating layer (4)
When Irradiation of High, due to TiOxN1-xFilm (2) absorption is larger, and temperature increases rapidly after absorbing laser energy,
The phase transition temperature for reaching the vanadium dioxide film layer (3) on its surface is undergone phase transition, and optical transmittance mutates, and the height by is thoroughly
Penetrating becomes high reflection, and photodetector is avoided to be damaged.Due to VO2Film layer (3) is easy in air due to oxidation etc.
Performance deterioration, so in VO2Thin-film surface prepares protective layer (4) again.
The technique effect of the present invention：
1, this intelligence laser protection mirror is simple in structure, and it is convenient to realize；
2, this intelligence laser protection mirror can realize the automatic protection to light laser；
3, support of this intelligence laser protection mirror without hardware such as other any external circuit, it is complete to the protection of light laser
Rely on itself right entirely.
