摘要
为了分析低能激光武器对人体皮肤组织的热损伤效应,依照人体皮肤组织的结构,建立了人体皮肤组织光热作用层状模型,并结合新型低能激光武器在实际应用中的作用条件,运用matlab中的有限元方法对激光照射下皮肤组织的温度进行数值模拟,得出使用过程中激光控制的能量密度限值。结果表明,当低能激光照射皮肤时间1s时,激光的功率密度不超过11.51 W/cm2时,不会对人体皮肤产生损伤;而当功率密度超过12.02 W/cm2时,就可能会产生不可逆损伤。依据模拟结果选取与其相邻近的几组数值进行照射实验,实验结果与模拟得出的结论基本吻合。
For analyzing hot injury effect of low energy laser weapons on human skin organization, Skin tissue pho- tothermolysis layered model is established in accordance with the structure of the human skin tissue. Consider a variety of factors, select the most suitable heat source term calculation method and the bio-heat transfer equation, combine with new non-lethal laser weapon conditions in practical applications and perform numerical simulation of skin tissue under laser irradiation temperature with the use of the finite element method in software matlab. Utilize thermal damage model of biological tissue and obtain laser energy control limits in using when skin irradiation time in laser is not more than 1 s, and the power 11.51 W/cm2, which does harm in the human skin injury. However, when may produce irreversible damage. The paper selects several sets of values mental results and simulation conclusion reach rough agreement. process. Derived by numerical simulation, density of the laser beam does not exceed the power density exceeds 12. 02W/cm2, it based on adjacent simulation results, experi-
