摘　　要：红外热辐射光源在光声光谱检测等领域具有重要的应用价值,明确其配光特性是后续光学系统设计的基础。根据水冷散热下红外热辐射光源辐射通量的变化规律,提出快速获取高功率红外热辐射光源配光特性的方法并对其进行相关验证。实验结果表明,光源辐射通量的最大值在80°的角度处,两侧的辐射通量缓慢减小,能量分散在0°~130°的角度范围内,其中54.5%的能量集中在50°~110°的角度范围内。在长时间稳定的辐射状态下对配光特性进行对比实验,验证快速测量方法的准确性和有效性。在ZEMAX软件中突破光源角度的限制,使用测得的数据建立模型并模拟实验流程进行验证。在缺少高功率红外热辐射光源配光曲线的情况下,所提方法可以简单快速地获取配光特性,为光学设计提供初始条件。Infrared thermal radiation light source has important applications value in such fields as photoacoustic spectroscopy detection,and its light distribution characteristic is the basis of subsequent optical system design.In this paper,according to the variation law of radiant flux of the infrared thermal radiation light source under water cooling,a method for quickly obtaining the light distribution characteristic of a high-power infrared thermal radiation light source is proposed and verified.The experimental results show that the radiant flux of the light source is at an angle of 80°,and the radiant flux on both sides decreases slowly,and the energy is dispersed in the range of 0°--130°,54.5%of which is concentrated in the range of 50°--110°.Furthermore,the accuracy and effectiveness of the rapid measurement method are verified through a comparative experiment of the light distribution characteristics under stable radiation for a long time.Beyond that,breaking the limit of light source angle in the ZEMAX software,the measured data is used to build a model and simulate the experimental process for verification.In conclusion,in the absence of the light distribution curve of the high-power infrared thermal radiation source,the proposed method can obtain the light distribution characteristics simply and quickly,providing initial conditions for optical design.
