Abstract: A method and surgical system including a laser source for generating a pulsed laser beam, an imaging system including a detector, shared optics configured for directing the pulsed laser beam to an object to be sampled and confocally deflecting back-reflected light from the object to the detector, a patient interface, through which the pulsed laser beam is directed, the patient interface having, a cup with a large and small opening, and a notched ring inside the cup; and a controller operatively coupled to the laser source, the imaging system and the shared optics, the controller configured to align the eye for procedure.

Abstract: Embodiments of this disclosure disclose an imaging system, including an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The beam source generates an electromagnetic radiation beam. The detection assembly generates a signal indicative of an intensity of a portion of the electromagnetic radiation beam reflected from the focal point location. A subsequent focal point of the electromagnetic radiation beam may be adjusted per the measured intensity signal. In some embodiments, an intensity signal below a lower threshold value may suggest a depth increase for a subsequent focal point. An intensity signal above an upper threshold value may suggest a depth decrease for a subsequent focal point. And, an intensity signal between the lower and upper thresholds may suggest a depth be maintained for a subsequent focal point. The focal point may be adjusted after each pulse or after a plurality of pulses.

Abstract translation: 本公开的实施例公开了一种成像系统，包括眼睛接口装置，扫描组件，束源，自由浮动机构和检测组件。 光束源产生电磁辐射束。 检测组件产生指示从焦点位置反射的电磁辐射束的一部分的强度的信号。 可以根据测量的强度信号调整电磁辐射束的后续焦点。 在一些实施例中，低于较低阈值的强度信号可以暗示后续焦点的深度增加。 高于上阈值的强度信号可以暗示后续焦点的深度减小。 而且，下限阈值和上限阈值之间的强度信号可能表明为后续焦点保持深度。 可以在每个脉冲之后或在多个脉冲之后调整焦点。
