高性能中波红外（IR）摄像机用于现场电子束熔化过程监测和温度测量。由于标准的工厂校准是不够的，由于非常低的传输所需的X射线吸收的含铅玻璃窗口，两种技术的温度校准进行了比较。发射度的现场测量也将被讨论。最终，这些成像系统具有常规使用的潜力，用于在线质量保证和反馈控制。
High performance mid-wave infrared (IR) cameras are used for in-situ electron beam melt process monitoring and temperature measurements. Since standard factory calibrations are insufficient due to very low transmissions of the leaded glass window required for X-ray absorption, two techniques for temperature calibrations are compared. In-situ measurement of emittance will also be discussed. Ultimately, these imaging systems have the potential for routine use for online quality assurance and feedback control.
