OPTICAL SENSOR WITH ANGLED REFLECTORS

Systems and methods for optical imaging using an optical sensor in an active area of the display are described. The optical sensor includes a set of detector elements positioned in a detector plane; atransparent layer; and a set of first reflective surfaces in the transparent layer. Each reflective surface in the first set of reflective surfaces is positioned to receive light from a portion of asensing region of the display and to reflect the received light. The optical sensor further includes a second set of reflective surfaces, each reflective surface in the second set of reflective surfaces is positioned to receive the transmitted light from the first set of reflective surfaces, and to further reflect the received light towards one of the set of detector elements. 描述了用于在显示器的活动区域中使用光学传感器进行光学成像的系统和方法。光学传感器包括定位在检测器平面中的组检测器元件；透明层；以及在透明层中的组第反射表面。第组反射表面中的每个反射表面被定位成接收来自显示器的部分感测区的光且反射所接收的光。光学传感器还包括第二组反射表面，第二组反射表面中的每个反射表面被定位成接收来自第组反射表面的所传送的光，并且还朝向该组检测器元件中的个反射所接收的光。
