    • An optical scanning device 1 detects an information signal from an optical record carrier 2 using differential interference contrast. Two radiation beams 13a, 13b are generated and focused to two distinct spots 15a, 15b respectively displaced along a data track on the information layer of an optical record carrier. The relative positions of the spots in lands and pits can generate a path length difference between the reflected beams 17a, 17b. This path length difference causes the beams to interfere either constructively or destructively, depending on the relative land/pit position in the data track of the spots. This interference causes a detectable signal to be generated, the signal being representative of a transition from a pit to a land on the information layer 4 or vice versa.
    • 光学扫描设备1使用差分干涉对比度来检测来自光学记录载体2的信息信号。 两个辐射光束13a,13b被产生并聚焦到分别沿着光学记录载体的信息层上的数据轨道移位的两个不同的点15a,15b。 斑点和凹坑中的斑点的相对位置可以在反射束17a,17b之间产生路径长度差。 这种路径长度差异会造成光束相长或相消干涉,这取决于光斑数据轨道中的相对纹间/凹坑位置。 这种干扰导致产生可检测信号,该信号代表信息层4上从坑到岸的过渡,反之亦然。
