A CPU provides a fluorescent light detecting head (104) with an irradiation instruction, in response to which the fluorescent light detecting head irradiates an ultraviolet ray (50) for detection on an ultraviolet curing resin material to be examined. The CPU then acquires from the fluorescent light detecting head an intensity of a fluorescent light (52) emitted from a photo polymerization initiator included in the ultraviolet curing resin material (12) when receiving the ultraviolet ray for detection. The CPU retrieves a predetermined number of past data of the intensity of the fluorescent light from a storage unit and performs a (moving) average calculation processing to calculate the intensity of the fluorescent light at the current time. The CPU performs an estimation processing of a state of the ultraviolet curing resin material based on the calculated intensity of the fluorescent light.
中央处理器向荧光检测头(104)提供照射指令,荧光检测头根据该指令照射紫外线(50),以便对待检测的紫外线固化
树脂材料进行检测。然后,CPU 从荧光检测头获取紫外线固化
树脂材料 (12) 中包含的光聚合
引发剂在接受紫外线检测时发出的荧光强度 (52)。中央处理器从存储单元中检索荧光强度的预定数量的过去数据,并执行(移动)平均计算处理,以计算当前时间的荧光强度。中央处理器根据计算出的荧光强度,对紫外线固化
树脂材料的状态进行估计处理。
