在海面波浪坡度场光学测量系统中,光源是一个非常重要的照明元件.合理的设计和选用光源,是保证系统精度和布局的重要因素之一.比较传统光源短弧氛灯的明显优势,如低能耗,寿命长,更好的安全性和稳定性等,本文提出了采用LED作为本系统光源的设想,确定了所需LED个数和LED阵列方式,并经过计算和光学软件模拟,验证了本设想的可行性.“,”Light source is a very significant lighting component,and plays a crucial role in the optical measuring process for wave slope field on sea surface.Rational selection of light source is one of the important factors for ensuring accuracy and layout of the system.Based on the advantages compared with short-arc xenon lamp as lighting in luminous efficiency,durability,reliability,safety and consuming power,LEDs are becoming the preferred candidate for many lighting applications that require uniform illumination distribution.An assumption that applied LEDs as light sources of the measuring device is presented,the feasibility has clarified by theoretical calculation and optical software simulation.
