One embodiment of the present invention is an ophthalmic wavefront sensor for use with an ophthalmic microscope to provide continuous measurements of the refractive state of an eye. The wavefront sensor operates in both parallel sampling and lock-in detection mode by synchronizing the pulsing of the light source with a multiple number of position sensing devices/detectors used for detecting the centroid position of the sampled sub-wavefronts. Other embodiments include a beam scanner to sample selected portions of the wavefront and a live image sensor and a tracking deflector.本發明之一實施例係一種用於與一眼科顯微鏡一起使用以對一眼睛之屈光狀態提供連續量測之眼科波前感測器。該波前感測器藉由使光源之脈動與用於偵測取樣子波前之形心位置之多個位置感測裝置/偵測器同步而以平行取樣及鎖定偵測模式進行操作。其他實施例包含一種用以取樣該波前之選定部分之光束掃描器及一種活動影像感測器及一種追蹤偏轉器。
