测试装置实施例：
参见图1，图1为本发明实施例提供的测试装置的结构示意图。该测试装置用于测试紫外成像仪7的灵敏度，如图所示，该装置可以包括：积分球1、可变光阑2和衰减片3。其中，积分球1设置有入光口11和出光口12，入光口11用于接收光源8发出的紫外光，出光口12用于输出照度均匀的紫外光。可变光阑2设置于积分球1的入光口11，该可变光阑2用于调节光源8发出的紫外光的光强。衰减片3设置于积分球1的出光口12，该衰减片3用于将照度均匀的紫外光衰减至具有预设辐射照度的紫外光。具体地，积分球1的入光口11与光源8相对应，出光口12与紫外成像仪7的入射口71相对应。对光源8发出的紫外光的光强调节是通过调节可变光阑2的孔径来实现的。
需要说明的是，具体实施时，预设辐射照度可以根据实际情况来确定，本实施例对此不做任何限制。
工作时，光源8发出的紫外光照射至积分球1的入光口11处，紫外光先经过可变光阑2再进入积分球1内。可变光阑2可将紫外光的光强调节至预设光强，具有预设光强的紫外光在积分球1内进行漫反射，形成照度均匀的紫外光。该照度均匀的紫外光由出光口12处输出，输出的紫外光经衰减片3进行衰减使得输出的紫外光的辐射照度为预设辐射照度，则具有预设辐射照度的紫外光照射至紫外成像仪7的入射口71。如果紫外成像仪7的入射口71接收到该具有预设辐射照度的紫外光，则确定该紫外成像仪7的灵敏度满足预设灵敏度。如果紫外成像仪7的入射口71未接收到该具有预设辐射照度的紫外光，则确定该紫外成像仪7的灵敏度不满足预设灵敏度。需要说明的是，该紫外成像仪7的预设灵敏度与紫外光的预设辐射照度相对应，不同的紫外成像仪7的预设灵敏度不同，则测试装置输出的紫外光的预设辐射照度也不同。
可以看出，本实施例中，通过设置积分球1，在积分球1的入光口11处设置可变光阑2，在积分球1的出光口12处设置衰减片3，这样光源8发出的紫外光依次经过可变光阑2、积分球1和衰减片3之后输出具有预设辐射照度的紫外光，该紫外光能够用于检测紫外成像仪7的灵敏度，解决了现有技术中无法检测紫外成像仪灵敏度的问题，进而有效地确保了紫外成像仪7检测结果的准确性。
继续参见图1，上述实施例中，该装置还可以包括：第一支撑体4。其中，第一支撑体4连接于积分球1的外壁且置于入光口11。可变光阑2可拆卸地连接于第一支撑体4。具体地，可变光阑2与第一支撑体4通过螺纹连接。具体实施时，第一支撑体4可以为圆柱体，且设置于积分球1的外部。
可以看出，本实施例的结构简单，易于实现，并且，可变光阑2通过第一支撑体4连接于积分球1，有效地确保了可变光阑2与积分球1之间的 稳定连接，避免了可变光阑2直接连接于积分球1导致的连接不牢固。
继续参见图1，上述各实施例中，该装置还可以包括：第二支撑体5。其中，第二支撑体5连接于积分球1的外壁且置于出光口12。衰减片3可拆卸地连接于第二支撑体5。具体地，衰减片3与第二支撑体5通过螺纹连接。具体实施时，第二支撑体5可以为圆柱体，且设置于积分球1的外部。
可以看出，本实施例的结构简单，易于实现，并且，衰减片3通过第二支撑体5连接于积分球1，有效地确保了衰减片3与积分球1之间的稳定连接，避免了衰减片3直接连接于积分球1导致的连接不牢固。
继续参见图1，上述各实施例中，衰减片3的数量小于等于3，这样确保了紫外光的预设辐射照度的计算准确，避免衰减片3设置太多导致的紫外光的预设辐射照度计算不准确。各衰减片3在积分球1的出光口12沿紫外光的传输方向依次设置。
上述各实施例中，积分球1的入光口11与出光口12位于积分球1的同一直径上。也就是说，入光口11的轴线与出光口12的轴线的连线为积分球1的直径。
继续参见图1，上述各实施例中，积分球1的入光口11至积分球1的球心的连线、与出光口12至积分球1的球心的连线之间的夹角β为钝角。优选的，大于等于135°，且小于180°。具体地，入光口11的轴线与球心的连线为L1，出光口12的轴线与球心的连线为L2，L1与L2之间的夹角为β。
继续参见图1，上述各实施例中，该装置还可以包括：光功率计6。其中，光功率计6设置于积分球1内，该光功率计6检测积分球1内紫外光的光功率。优选的，光功率计6为光电传感器。更优选的，该光功率计6的型号为NOVAⅡ。
下面结合附图1和附图2对本发明实施例中的测试装置进行详细说明。
由于不同的紫外成像仪的灵敏度是不同的，所以测试装置输出的紫外 光的预设辐射强度需要根据不同的紫外成像仪的灵敏度进行调节，以使紫外光的预设辐射强度与紫外成像仪的灵敏度相匹配，从而根据紫外成像仪是否能够接收到该紫外光来检测紫外成像仪的灵敏度是否满足预设灵敏度。
具体地，积分球1输出的紫外光的辐射照度的调节方法如下：
光源8发出的紫外光通过可变光阑2输入至积分球1内，积分球1内的光功率计6检测积分球1内紫外光的光功率，并将检测到的紫外光的光功率值记为P1。
(1)根据公式
Figure PCTCN2017087070-appb-000001
计算光源的辐射强度Ie。
(2)根据公式
Figure PCTCN2017087070-appb-000002
计算光源的立体角Ω，上式中的d1为可变光阑的半径，l为光源至可变光阑的距离。
(3)根据公式
Figure PCTCN2017087070-appb-000003
计算积分球内紫外光的辐射通量Φ1。
(4)根据公式
Figure PCTCN2017087070-appb-000004
计算积分球内的紫外光的辐射照度E1，上式中的r1为积分球的半径，η1为积分球的反射率。
(5)根据公式τ＝10-光密度*100％确定衰减片的透过率τ，上式中的光密度值为衰减片的性能参数。
(6)根据公式E0＝E1*τ计算出积分球输出的紫外光经衰减片衰减后的辐射照度E0，该E0即为与紫外成像仪的灵敏度相匹配的紫外光的辐射照度。
具体实施时，积分球的反射率η1可以取1，衰减片可以选择3个，各衰减片的光密度可以为2、3、3。
通过上述计算方法可知，当积分球的反射率η1、积分球的半径r1、选择的衰减片的数量、衰减片的光密度值均为定值时，随着可变光阑的半径 d1和/或光源至可变光阑的距离l发生变化，积分球内的紫外光的辐射照度E1也会发生变化，进而积分球1输出的紫外光经衰减片3衰减后的辐射照度E0也会相应的变化。因此，当紫外成像仪7的预设灵敏度确定之后，可以根据该预设灵敏度确定所需的紫外光的预设辐射照度E0。根据该预设辐射照度值E0与积分球内的紫外光的辐射照度E1和衰减片透过率τ之间的关系，调节可变光阑的半径d1、光源至可变光阑的距离l以及确定衰减片3的个数和衰减片3的光密度值以使计算出的紫外光的辐射照度为预设辐射照度E0。
当测试装置测试不同的紫外成像仪7的灵敏度时，根据上述调节方法调节可变光阑的半径d1、光源至可变光阑的距离l以及确定衰减片3的个数和衰减片3的光密度值即可使得测试装置输出的紫外光的预设辐射照度与紫外成像仪7的预设灵敏度相对应。当确定测试装置输出的紫外光为预设辐射照度时，将光源8输出的紫外光依次经过可变光阑2、积分球1和衰减片3照射至紫外成像仪7的入射口71，根据紫外成像仪7的入射口71是否检测到该紫外光来判断紫外成像7的灵敏度是否满足预设灵敏度。
综上所述，本实施例中，通过设置积分球1，在积分球1的入光口11处设置可变光阑2，在积分球1的出光口12处设置衰减片3，这样光源8发出的紫外光依次经过可变光阑2、积分球1和衰减片3之后输出具有预设辐射照度的紫外光，该紫外光能够用于检测紫外成像仪7的灵敏度，进而有效地确保了紫外成像仪7检测结果的准确性。

具体地，测试装置输出的具有预设辐射照度的紫外光照射紫外成像仪7的入射口71，紫外成像仪7通过入射口71检测是否接收到该紫外光。
确定步骤S3，根据判断结果确定紫外成像仪是否满足预设灵敏度。
具体地，当紫外成像仪7接收到紫外光时，确定紫外成像仪7满足预设灵敏度；当紫外成像仪7未接收到紫外光时，确定紫外成像仪7不满足预设灵敏度。具体实施时，预设灵敏度可以根据紫外成像仪7进行确定，本实施例对此不做任何限制。
