[0038] 如图 2所示， 本发明一种组合式光谱探头 10,包括光谱探头 11、 摄像头 12、 宽带 照明光源 13、 发射光纤 14、 接收光纤 15以及连接电缆 16 (即连接导线） 组合在 一起形成组合式光谱探头。 在图 2中， 17是激发光、 18是激发光 17与被检测物质 相互作用而产生的光、 19是宽带照明光、 20是摄像头 12接收的光。 其中光谱探 头 11由发射光学系统和接收光学系统组成， 且有相应的二向性滤光片以滤掉返 回的激发光， 以减少其对激发光 17与被检测物质相互作用而产生的光 18探测的 干扰， 光谱探头 11用于发射激发光 17以及接收激发光与被检测物相互作用而产 生的光 18; 摄像头 12用于拍摄记录被检测物质、 分析或实验过程、 使用者和设 备仪器的图像； 宽带照明光源 13用于提供摄像头 12进行拍摄所需的照明。 从而 使得组合式光谱探头 10具有发射激发光 17以及接收激发光与所述被检测物相互 作用而产生光 18的功能， 又具有录像功能。 所以能在进行光谱分析过程的同吋 ， 记录被鉴别物质、 分析或实验过程、 使用者和分析或实验所用的设备仪器等
[0039] 发射光纤 14和接收光纤 15; 发射光纤 14用于接收来自激发光源 20的激发光 17并 传输激发光至光谱探头 11后再经发射光学系统射向被检测物 200; 当激发光 17与 被检测物质相互作用而产生的光 18后， 经光谱探头 11内的接收光学系统接收后 导入接收光纤 15并传输至光谱分析器 30(见图 6)进行光谱分析。 连接电缆 16用于 传输控制显示装置 40 (见图 6)发出的控制信号,并将摄像头 12所获得图像传回控 制显示装置 40。 同样的， 控制显示装置 40还与激发光源 17以及光谱分析器 30通 过电缆连接， 以控制激发光源 17以及光谱分析器 30。
[0040] 优选的是， 根据本发明的组合式光谱探头， 所述激发光源 20(见图 6)为激光器吋 ， 根据所用不同的二向性分光片， 当所述激光与所述被检测物质 200相互作用而 产生的光 18为拉曼光吋， 则组合式光谱探头 10可用做为拉曼光谱探头； 当所述 激光与所述被检测物质 200相互作用而产生的光 18为荧光吋，
则组合式光谱探头 10可用做为荧光光谱探头。
[0041] 或根据本发明的组合式光谱探头 10， 所述激发光为非激光 （如紫外灯光等） 吋 ， 根据所用不同的二向性分光片， 当所述非激光与所述被检测物相互作用而产 生的光为荧光吋， 则组合式光谱探头 10也可用做为荧光光谱探头。
[0042] 图 3是本发明组合式光谱探头 10另一实施例的示意图。 与图 2中不同的是， 在图 2中， 摄像头 12和宽带照明光源 13同向设置， 且摄像头 12与光谱探头 11同向设置 。 然而在图 3中， 摄像头 12和宽带照明光源 13同向设置， 且摄像头 12与光谱探头 11具有一任意夹角 a以更方便对被鉴别物质、 分析或实验过程、 使用者和分析或 实验所用的设备仪器等的进行照明和摄像记录。
[0043] 图 4是本发明组合式光谱探头 10又一实施例的示意图。 与图 2和图 3中不同的是 ， 在本实施例中， 宽带照明光源 13的照射方向前端还设置有第一滤光器 414， 第 一滤光器 414为单一滤光片、 滤光片组合或滤光片与中性衰减滤光片的组合以获 得不同光谱不同强度的照明。 也即该第一滤光器 414可以是单个的滤光片， 该单 个的滤光片可以根据需求进行选择以获得不同的光谱照明， 同吋该第一滤光器 4 14可以是多个滤光片的组合以获得不同的光谱照明， 另外第一滤光器 414也可以 是滤光片与中性衰减滤光片的组合以获得不同光谱不同强度的照明， 中性衰减 滤光片是为了降低宽带照明光源 13所发出光的光强。
[0044] 图 5是本发明组合式光谱探头 10再一实施例的示意图。 与图 2至图 4中不同的是 ， 在本实施例中， 摄像头 12的拍摄镜头前端还设置有第二滤光器 515， 第二滤光 器 515为单一滤光片、 滤光片组合或滤光片与中性衰减滤光片的组合以获得不同 光谱不同强度的图像。 也即该第二滤光器 515可以是单个的滤光片， 该单个的滤 光片可以根据需求进行选择以使摄像头 12获得不同的光谱的图像， 同吋该第二 滤光器 515可以是多个滤光片的组合以使摄像头 12获得不同的光谱图像， 另外第 二滤光器 515也可以是滤光片与中性衰减滤光片的组合以获得不同光谱不同强度 的图像， 中性衰减滤光片的是为了降低摄像头 12所接收到的光的光强， 以避免 因光太强导致摄像头 12饱和而影响正常工作。
[0045] 显而易见， 在其他实施例中， 也可同吋在宽带照明光源 13的照射方向前端、 摄 像头 12的拍摄镜头前端均设置滤光器， 以获得不同光谱不同强度的照明或图像
[0046] 综上所述， 本发明通过将光谱探头、 摄像头以及宽带照明光源组合在一起形成 组合式光谱探头， 其中光谱探头用于发射所述激发光以及接收激发光与被检测 物相互作用而产生的光； 摄像头用于拍摄记录被鉴别物质、 分析或实验过程、 使用者和设备仪器的图像； 宽带照明光源用于提供摄像头进行拍摄所需的照明 。 从而使得光谱探头具有发射激发光以及接收激发光与所述被检测物相互作用 而产生的光的功能， 又具有录像功能。 在进行光谱分析过程的同吋， 记录被鉴 别物质、 分析或实验过程、 使用者和分析或实验所用的设备仪器等。
