具有芯片上滤波器及延展频谱响应的固态图像传感器
摘要：
各个实施例涉及一种图像传感器，其包含第一传感器部分及第二传感器部分。所述第二传感器部分可相对于所述第一传感器部分定位，使得所述第二传感器部分最初可检测进入所述图像传感器的光，且所述光中的一些通过所述第二传感器部分且可由所述第一传感器部分检测。在一些实施例中，一多个光学滤波器可安置于所述图像传感器内。所述一或多个光学滤波器可包含以下各者中的至少一者：双带通滤波器，其安置于第二光检测器上方；或窄带通滤波器，其安置于第一光检测器与所述第二光检测器之间。
摘要（英）：

Various embodiments are directed to an image sensor that includes a first sensor portion and a second sensor portion. The second sensor portion may be positioned relative to the first sensor portion such that the second sensor portion may initially detect light entering the image sensor, and some of that light passes through the second sensor portion and may be detected by the first sensor portion. In some embodiments, one more optical filters may be disposed within the image sensor. The one or more optical filters may include at least one of a dual bandpass filter disposed above the second photodetector or a narrow bandpass filter disposed between the first photodetector and the second photodetector.
