摘　　要：面源黑体作为红外源标在红外测温、红外成像、红外相机标定等领域广泛应用,红外源标红外辐射性能主要取决于面源黑体温度场的控制。为了适应星载和机载红外探测器大孔径、大视场角的发展需求,文中对超大尺寸面源黑体温度控制技术进行了研究。外场条件下,面源黑体会随着尺寸的增大而增加温度控制的难度,控温系统采用两相流体回路技术实现了外场3m×3m面源黑体不同目标温度下高温度均匀性、稳定性温度控制,试验结果表明,黑体表面温度均匀性控制优于±0.60℃,稳定性控制优于0.14℃/15min。As an infrared standard source,surface blackbody is widely used in infrared temperature measurement,infrared imaging,infrared camera calibration and other fields.The infrared radiation performance of infrared standard source mainly depends on the control of surface blackbody temperature field.In order to meet the development needs of large aperture and large field of view of spaceborne and airborne infrared detectors,the temperature control technology of extra large surface blackbody is studied in this paper.Under the condition of outfield,the difficulty of temperature control increases with the increase of surface blackbody size.The temperature control system adopts the two-phase fluid loop technology to realize the high temperature uniformity and stability temperature control of a 3m×3m surface blackbody for the outfield field under different target temperatures.The experiment results show that the surface temperature uniformity control of the black body is better than ±0.60℃ and the stability control is better than 0.14℃/15 min.
