Description
Technical Field
The invention belongs to the field of laser injury assessment, and particularly relates to a laser non-lethal weapon injury assessment method.
Background
Unlike traditional lethal weapons, laser non-lethal weapons are primarily characterized by their non-lethal and injury-restorability under certain conditions of action on the target of irradiation. Although laser non-lethal weapon has some advantages, it has many safety problems in application, such as no strict limit to laser lethal weapon, when laser energy is too high or the action distance is short and the action time is long, the target may be permanently blinded, and non-lethal injury assessment has not yet established a unified judgment standard. In order to establish a scientific and credible injury evaluation system, standardize the research and development and use operation of a laser weapon and related optical equipment, prevent misuse of related laser equipment and even the weapon, reduce the casualties of innocent persons, expand the application range of the laser non-lethal weapon and promote the healthy development of the laser non-lethal weapon, the establishment of a laser non-lethal weapon injury evaluation method and an evaluation model is one of the key links for carrying out the laser non-lethal weapon injury evaluation system.
At present, in the field of laser non-lethal injury assessment, mature and perfect theories and techniques are not established in China, a practical application system is not established, and rough injury assessment becomes a bottleneck limiting the fighting efficiency of an assessment system. Previous studies were isolated, either purely studying laser non-lethal weapon efficacy assessments, or purely studying laser injury experiments, without combining the two. Also, the conventional evaluation method generally divides retinal damage into three grades of mild, moderate, and severe, and determines the degree of laser damage using the three grades. The method has the defects that only qualitative research is carried out, when two laser powers emitted by the lasers are high but the numerical values are not greatly different, the damage to the retina under the two laser powers can be severe damage, the damage degree cannot be refined in a quantitative mode, and the visual feeling cannot be brought to people.

step 5, establishing a damage quantitative model and a damage evaluation parameter PeThe one-to-one correspondence relationship between the laser non-lethal weapon injury evaluation models P is establishedke＝f(Pe)；
And 6, integrating the step 4 and the step 5, perfecting the laser non-lethal weapon injury evaluation method: the maximum living target visual function loss probability value which does not cause damage more than extremely severe in the fitted laser non-lethal weapon injury evaluation model is combined to distinguish the severe damage from the extremely severe damage; the maximum value of the probability value of visual function loss of living targets is 1, so that extremely severe injuries and death are distinguished, and a complete laser non-lethal weapon injury evaluation grade table is obtained.

Detailed Description
The invention is further described with reference to the following figures and embodiments.
The invention designs a laser non-lethal weapon injury evaluation method, and the flow chart of the implementation method is shown in figure 1. The method establishes the laser non-lethal weapon injury evaluation method and the evaluation model by analyzing injury factors, using laser injury test data and an ophthalmological detection result 24 hours after laser irradiation, quantizing a laser injury area, selecting appropriate evaluation parameters, selecting an appropriate function to fit to obtain a relationship between an injury quantization model and the evaluation parameters and the like, and specifically comprises the following steps:
step 1, as shown in fig. 2, analyzing the injury factors of the laser non-lethal weapon, and selecting a reasonable injury evaluation parameter, namely effective laser power density Pe。
Firstly, determining the injury factors of the laser non-lethal weapon, wherein the injury factors of the laser for damaging the target, such as wavelength, intensity, power density and action time, are selected and analyzed.
The shorter the laser wavelength, the higher the energy, the more intense the damage to the eye tissue and, conversely, the less damage to the retina. The transmittance and absorbance of human eye tissue varies with wavelength. The absorption rate of the fundus for the laser light increases with increasing wavelength within a certain range, and beyond this critical wavelength, the absorption rate decreases with increasing wavelength. Therefore, the laser wavelength is low in absorption rate thereof by the fundus, and even if it reaches the fundus, accumulation of light energy is reduced and damage to the fundus is small. Therefore, laser non-lethal weapon injury factors have certain correlation with wavelength. However, this ignores the energy of the emitted laser beam, the output power of the laser, and the effective absorption rate of the living eye tissue.
To achieve a non-lethal effect, the intensity of the laser emitted by a laser non-lethal weapon must satisfy certain conditions, at least a minimum retinal damage threshold. Otherwise, if the laser intensity is low, even if the irradiation time is longer, the eye tissue can not be damaged, and the purpose of causing blindness and injury can not be achieved. The laser intensity is used as an evaluation parameter, and although some problems are compensated and certain rationality is provided, the degree of damage to the eye tissue of the organism is not only related to the laser intensity, but also related to the action time.
For a certain wavelength of laser light, its power (energy) density determines the degree of damage to the human eye. For the same continuous wavelength laser, the higher the laser power (or energy) density, the more severe the eye tissue damage. The damage effect is related to the laser pulse width for the same laser power density. In general, the damaging effect of long pulse lasers is weak compared to short pulses. Under the condition of a certain single pulse energy, the smaller the pulse width is, the higher the peak power is, and the more serious the eye injury is. However, the effective absorption rates of eye tissues to different wavelengths are different, the laser power densities entering the eye tissues are different, and the laser power densities serving as the injury effect evaluation parameter indexes of the laser non-lethal weapons have certain defects.
For continuous laser light, the degree of damage is also closely related to the time the laser light is applied to the eye (referred to as exposure time for short): the longer the duration of action, the more light energy that enters the eye and the more heavily the eye is damaged. However, the laser intensity is low, and even if the irradiation time is longer, the eye tissue cannot be damaged, so that the purpose of causing blindness and injury cannot be achieved. The laser action time is controlled to be 2 s.
The method and the thought for taking the effective laser power density which enters the eye tissue and is absorbed by the retina as the injury evaluation parameter are provided by comprehensively considering the advantages and disadvantages of the traditional injury evaluation parameter on the laser non-lethal injury effect evaluation and combining the different influences of the eye tissue on the absorption and transmission of the laser with different wavelengths.
Effective laser power density is defined as the amount of laser light received by the retina of an eye tissue that causes the eye tissue to produce when the eye tissue of a living being is irradiated with laser lightLaser power density of damage PeThe relationship between the power density P of the laser and the laser power in a certain space distribution is
Pe＝P×η (1)
Wherein, P is the laser power density at a certain point in space, and the value is the laser power of the laser at the point divided by the laser spot area at the point; eta is the effective absorption rate of retina. For laser non-lethal weapons with different wavelengths, when the laser power density of the emitted laser at a certain action point in space is the same, the effective laser power density P absorbed by retina of eye tissue of organismeThis is due primarily to the difference in the effective absorption rate of the retina, which results in a difference in the laser power density entering the retina. For a 532nm laser, η is 65%.
Step 2, collecting the optic disc and laser damaged area, quantifying the diameter of the optic disc and laser damaged area, specifically, according to the injury experiment of the laser non-lethal weapon on biological eye tissue and the ophthalmologic detection result 24h after laser irradiation, wherein the organism selected in the injury experiment is a blue rabbit, and the round or approximately round shape of the rabbit eye optic disc and laser damaged area is found, and the specific operation process comprises the following steps: the key detection result capable of representing the damage is photographed and printed, the laser damage area and the area of the organism eye tissue optic disc are drawn on coordinate paper, the area of the laser damage area and the organism eye tissue optic disc is determined by the number of grids, and the equivalent diameter of the organism eye tissue optic disc can be determined by the area formula of a circle.
For a noncircular or strip-shaped laser damage area, the damage can be converted into a circular area for treatment, and the operation process comprises the following steps: the key detection result capable of representing the damage is photographed and printed, a laser damage area and an area of an organism eye tissue optic disc are drawn on coordinate paper, the areas of the laser damage area and the organism eye tissue optic disc are determined by counting the number of grids, and the equivalent diameter of the organism eye tissue optic disc can be determined by a circle area formula. Note that in the laser injury test, when the laser power density is high, the laser irradiates the eye tissue of the organism once, the eye tissue is inspected by an ophthalmologic detection instrument to find that a laser injury area is left, and the actual injury condition can be truly reflected 24 hours after the laser irradiation; when the laser power density does not reach the retinal damage threshold, even if the living body eye is irradiated with the laser, the living body retina is not damaged, and thus, no laser damage region is left on the retina.
The laser power density of the laser emission power of 1000mW at 4m is 2318.18mW/cm under the illumination of the daytime environment by using 532nm laser wavelength without using a beam expander2For example, to quantify the damage, there are 5 laser damage regions, of which 3 are shown in fig. 3, the diameters of the optical disks are denoted as PD, the diameters of the 3 laser damage regions are 2/3PD, 1/2PD and 1/3PD, and 2 are shown in fig. 4, and the diameters of the two laser damage regions are 3/4 PD.
In the above case, the laser power density was 2318.18mW/cm, since the laser has the same action conditions on the eye tissue2Irradiating for 5 times to leave 5 laser damaged regions on retina, and calculating average value of the 5 laser damaged regions to reduce error, wherein the damaged diameter is denoted as R 13/5 PD. Then under the action of the laser, there is a probability P of visual function loss of the living subjectke＝R1and/PD is 0.6. With living target visual function loss probability PkeValue to measure the extent of damage, PkeLarger values represent more severe retinal damage.
Step 4, integrating the step 2 and the step 3, and preliminarily determining a laser non-lethal weapon injury evaluation method: and combining a damage grade qualitative method with a damage quantitative model quantitative method.
The whole laser biological injury test controls the laser action time to be 2s, combines the actual situation, in order to explain the injury degree in more detail, further subdivides the severe injury into severe injury, extremely severe injury and death, and defines the injury characteristic according to grades, establishes a preliminary laser non-fatal injury evaluation grade table (shown as table 1), and the table is combined with an injury evaluation model to obtain a complete and detailed injury grade table (shown as table 6).
TABLE 1 preliminary evaluation grade table for laser non-lethal injury
Step 5, establishing a damage quantitative model and a damage evaluation parameter PeAnd establishing a laser non-lethal weapon injury evaluation model according to the one-to-one correspondence relationship between the laser non-lethal weapon injury evaluation models.
Combining the probability value of visual function loss of the living target under the laser injury test condition (shown in table 2) and the effective laser power density value under the laser injury test condition (shown in table 3), step 4 and step 5 to obtain the visual function loss probability P of the living targetkeThe correspondence with the effective laser power density is shown in table 4.

TABLE 3 effective laser power density values under laser induced damage test conditions
TABLE 4 relationship between effective laser power density and probability of visual function loss of living target
Analyzing the data in table 4, it can be seen that when the effective laser power density is small, the probability value of visual function loss of the living target increases more rapidly along with the increase of the effective laser power density; after the effective laser power density is increased to a certain value, the probability value of visual function loss of the living target begins to increase slowly, mathematically, the probability value does not exceed 1, and it is expected that if the effective laser power density is continuously increased, the probability value of visual function loss of the living target does not increase rapidly all the time, and tends to be stable after reaching the certain value, and the stable value is the maximum value of the probability of visual function loss of the living target. From this analysis it can be seen that the effective laser power density PeProbability of visual function loss with living target PkeThe relationship between the two is more consistent with the relationship of the S-shaped function, so the Logstic function is selected by the fitting model.
According to Pke＝f(Pe) The probability P of visual function loss of living target can be obtainedke，Pke∈[Ai，Ai+1) Further, the damage level of the living eye tissue at the effective laser power density is determined.
Wherein the content of the first and second substances,
Aithe critical probability of the damage grade is determined by a laser injury test, two conditions are met, firstly, the laser injury test can be conformed to the laser injury test, secondly, the laser injury test made by a predecessor can be verified, andthe goodness of fit is high; riThe diameter of the critical damage grade area is obtained by averaging under the condition; PD is the diameter of the optic disc of the eye tissue of the organism; i is 1, …, 6 denotes the i-th damage level index.
Analyzing the data in table 4, it can be seen that when the effective laser power density is small, the probability value of visual function loss of the living target increases more rapidly along with the increase of the effective laser power density; after the effective laser power density is increased to a certain value, the probability value of visual function loss of the living target begins to increase slowly, mathematically, the probability value does not exceed 1, and it is expected that if the effective laser power density is continuously increased, the probability value of visual function loss of the living target does not increase rapidly all the time, and tends to be stable after reaching the certain value, and the stable value is the maximum value of the probability of visual function loss of the living target. From this analysis it can be seen that the effective laser power density PeProbability of visual function loss with living target PkeThe relationship between the two is more consistent with the relationship of the S-shaped function, so the Logstic function is selected by the fitting model. Based on the Logistic function equation y ═ A2+(A1-A2)/(1+(x/x0)p) The fitted living target visual function loss probability curve is shown in fig. 5.
Obtaining by fitting for laser with wavelength of 532 nm: a. the1＝0.02489，A2＝0.8613，Pe0＝695.28，p＝0.8586。
Fitting to obtain A1，A2，Pe0P, etc. fitting parameters, A1To minimize the probability of visual function loss of the living target causing the injury, A2Maximum probability of visual function loss of living target without causing more than extremely severe injury, Pe0As the central value, p is the power exponent.
And 6, integrating the step 4 and the step 5, perfecting the laser non-lethal weapon injury evaluation method: the maximum living target visual function loss probability value which does not cause damage more than extremely severe in the fitted laser non-lethal weapon injury evaluation model is combined to distinguish the severe damage from the extremely severe damage; the maximum value of the probability value of visual function loss of living targets is 1, so that extremely severe injuries and death are distinguished, and a complete laser non-lethal weapon injury evaluation grade table is obtained.
Injury evaluation model P obtained according to fittingke＝f(Pe) I.e., equation (2), the corresponding relationship between the different probabilities of visual function loss and the damage levels can be obtained, as shown in table 5.
