摘要:
An image detecting apparatus for detecting an object including a light source, a light mask, a lens module, a image detecting unit and a control unit is provided. The light source provides an illumination beam. The light mask is disposed on the transmission path of the illumination beam and has a light transmissive aperture. The illumination beam propagates through the light mask via the light transmissive aperture. The lens module is disposed on the transmission path of the illumination beam from the light transmissive aperture. The object reflects the illumination beam into an image beam. The lens module is disposed on the transmission path of the image beam. The image detecting unit is disposed on the transmission path of the image beam from the lens module. The control unit makes the image detecting unit and the light mask move according to the shift condition of the image detected by the image detecting unit. An image detecting method is also provided.一種影像偵測裝置,用以偵測一待測物,影像偵測裝置包括一光源、一光遮罩、一鏡頭模組、一影像偵測單元及一控制單元。光源提供一照明光束。光遮罩配置於照明光束的傳遞路徑上並具有一透光開孔。照明光束經由透光開孔通過光遮罩。鏡頭模組配置於來自透光開孔的照明光束的傳遞路徑上。待測物將照明光束反射成一影像光束。鏡頭模組配置於影像光束的傳遞路徑上。影像偵測單元配置於來自鏡頭模組的影像光束的傳遞路徑上。控制單元根據影像偵測單元所偵測到的影像的偏移狀態來使影像偵測單元與光遮罩移動。一種影像偵測方法亦被提出。10‧‧‧影像偵測裝置20‧‧‧待測物100‧‧‧光源110‧‧‧光遮罩120‧‧‧鏡頭模組122‧‧‧前透鏡群124‧‧‧分光單元126‧‧‧第一後透鏡群128‧‧‧第二後透鏡群129‧‧‧反射器130‧‧‧影像偵測單元131‧‧‧第一致動器132‧‧‧第二致動器140‧‧‧控制單元B、B0、B1、B2‧‧‧影像光束d1‧‧‧偏移量J1‧‧‧第二對應移動量L、L0、L1、L2‧‧‧照明光束M1‧‧‧第一對應移動量200、201、202、1300、1301、1302、F0、F1、F2、P0、P1、P2‧‧‧位置
