The invention relates to an ultraviolet laser sterilization system. It comprises an ultraviolet laser module, and a scanning module to manufacture a sterilization scanner. The ultraviolet laser module emits an ultraviolet laser light with the wavelength ranging from 200nm to 280nm. The scanning module includes a plurality of reflectors for receiving the ultraviolet laser light, and a controller for controlling the rotation of the reflectors to adjust an emergence angle of the ultraviolet laser light for a sterilizing action on a target. Accordingly, a collimated advantage of the laser can be combined with a sterilization effect of the UV-C to save effectively time and manpower costs by the simplest way and achieve the comprehensive sterilization and disinfection effects with the radiation rapidly and flawlessly.本發明係有關於一種紫外雷射滅菌系統,主要包括有一紫外雷射模組,以及一掃描模組,以製成一滅菌掃描儀;該紫外雷射模組係發出一紫外雷射光,其中該紫外雷光之波長係介於200奈米~280奈米之間;掃描模組係包括複數個接收該紫外雷射光之反射鏡,以及一控制該等反射鏡轉動以調整該紫外雷射光出射角之控制器,以進行目標物上之滅菌動作;藉此,結合雷射光之準直性優點以及UV-C之殺菌消毒效果,有效以最簡單的方式達到節省人力與時間之成本,且快速而無死角之全面性輻射殺菌與消毒之作用。(1)‧‧‧紫外雷射模組(11)‧‧‧紫外雷射光(2)‧‧‧掃描模組(21)‧‧‧反射鏡(22)‧‧‧控制器(3)‧‧‧臭氧偵測模組(4)‧‧‧目標物
