    摘要: There is provided a method for imaging an object, the method comprising the steps of: accommodating a positioning of the object relative to an imaging system. A shape of the object is describable in terms of one or more shape parameters and the method includes creating scan data by determining a coordinate of the object at a set of points along an arc by the imaging system, wherein the coordinate of the object is a Z coordinate of an object layer. The method further includes determining an object shape parameter and an object position parameter based on the scan data by a system control module by extracting an amplitude and a phase of the scan data; and determining a center of the object layer based on the extracted amplitude and phase.

    摘要: Designs and techniques for constructing and operating femtosecond pulse lasers are provided. One example of a laser engine includes an oscillator that generates and outputs a beam of femtosecond seed pulses, a stretcher-compressor that stretches a duration of the seed pulses, and an amplifier that receives the stretched seed pulses, amplifies an amplitude of selected stretched seed pulses to create amplified stretched pulses, and outputs a laser beam of amplified stretched pulses back to the stretcher-compressor that compresses their duration and outputs a laser beam of femtosecond pulses. The amplifier includes a dispersion controller that compensates a dispersion of the amplified stretched pulses, making the repetition rate of the laser adjustable between procedures or according to the speed of scanning. The laser engine can be compact with a total optical path of less than 500 meters, and have a low number of optical elements, e.g. less than 50.
