Using a calibrated hyperspectral camera, we evaluated the hazard risk level of blue light illumination using the IEC TR 62778:2014 method. The risk levels obtained using the hyperspectral camera were compared with those obtained using the method described in the IEC 62471:2006 guidelines. The IEC TR 62778:2014 risk level of each test product was the same as that obtained using the IEC 62471:2006 method. Compared with the evaluation method implemented using a conventional single-point measurement, our approach using a hyperspectral camera obtained spectral radiance measurements in a much shorter time, of the order of several seconds, via two-dimensional measurements.

研究报告：使用高光谱相机测量蓝光危害风险级别

使用经过校准的高光谱相机，我们使用 IEC TR 62778:2014 方法评估了蓝光照明的危害风险级别。将使用高光谱相机获得的风险级别与使用 IEC 62471:2006 指南中描述的方法获得的风险级别进行比较。每个测试产品的 IEC TR 62778:2014 风险级别与使用 IEC 62471:2006 方法获得的风险级别相同。与使用传统单点测量实现的评估方法相比，我们使用高光谱相机的方法通过二维测量在几秒钟的时间内获得了光谱辐射测量值。
