摘要： A focal position detecting apparatus, for detecting a focusing condition and a tilting condition of an object, includes a planar beam generating module, an optical system, an optical sensor and a cylindrical lens. The planar beam generating module generates a planar light beam along a first path. The optical system is disposed on the first path, wherein the planar light beam, reflected by the object, passes through the optical system along a second path. The optical sensor is disposed on the second path. The cylindrical lens is disposed on the second path between the optical system and the optical sensor and an axis of the cylindrical lens is perpendicular to the second path. The planar light beam passes through the optical system and the cylindrical lens along the second path, before it is incident on the optical sensor to form a linear light spot for determining defocusing degree.

摘要： An auto-focusing apparatus with timing-sequential light spots includes a light source, a lens, a timing-sequential light dividing module, a focusing element and a processing module. The light source produces an incident beam. The lens collimates the incident beam that is an unsymmetrical beam relative to the lens to a collimation beam. The timing-sequential light dividing module divides the collimation beam into multiple sub-beams in timing sequence. The focusing element focuses the sub-beams to an observed object. The processing module senses energy distribution of multiple reflected beams of the observed object corresponding to the sub-beams to accordingly calculate energy centroids of the reflected beams.
摘要翻译：具有定时顺序光点的自动对焦装置包括光源，透镜，定时顺序光分割模块，聚焦元件和处理模块。光源产生入射光束。透镜将作为相对于透镜的不对称光束的入射光束准直到准直光束。时序顺序光分割模块按照时序顺序将准直光束分成多个子光束。聚焦元件将子光束聚焦到观察对象。处理模块感测对应于子光束的观测物体的多个反射光束的能量分布，从而相应地计算反射光束的能量质心。
