    • A sensing method and system for Fresnel lenses are disclosed, the system including a first Fresnel lens unit for sensing the signal of a target object crossing a first boundary of a sensing area, a second Fresnel lens unit for sensing the signal of a target object crossing a second boundary of the sensing area, a third Fresnel lens unit for sensing the signal of a target object crossing a third boundary of the sensing area, and a sensing unit for receiving and processing the sensed signals of the Fresnel lens units. The first and second Fresnel lens units are arranged on two sides of the third Fresnel lens unit. Furthermore, it is possible to add more Fresnel lens units above, below or around the Fresnel lens units. By monitoring the boundaries of the sensing area, the sensing method and system for the Fresnel lenses improve the insufficiency of the sensing area, reduce cost and save power consumption.
    • 公开了一种用于菲涅尔透镜的感测方法和系统,该系统包括用于感测与感测区域的第一边界相交的目标物体的信号的第一菲涅耳透镜单元,用于感测目标物体交叉信号的第二菲涅耳透镜单元 感测区域的第二边界,用于感测与感测区域的第三边界相交的目标物体的信号的第三菲涅耳透镜单元,以及用于接收和处理感光单元的感测信号的感测单元。 第一和第二菲涅耳透镜单元布置在第三菲涅耳透镜单元的两侧。 此外,可以在菲涅耳透镜单元的上方,下方或周围添加更多的菲涅尔透镜单元。 通过监测感测区域的边界,菲涅尔透镜的感测方法和系统可以提高感测区域的不足,降低成本并节省功耗。
