使用多光子脉冲内干涉相位扫描(MIIPS)的飞秒脉冲特性和补偿[opt.让我们来吧。29,775(2004)]受到了严格的测试。MIIPS在90 nm的脉冲带宽内具有3mrad的精度。玻璃和石英的群速度色散测量提供了独立的精度测试。使用MIIPS测量和校正了来自大数值孔径物镜的相位失真，这是可重现双光子显微镜的重要要求。相位补偿通过将连续的和二进制的相位函数更准确地传递到样本，极大地改善了脉冲整形结果。MIIPS的测量可以通过生物组织的散射来实现，这是生物医学成像的一个考虑因素。(C)2006年美国光学学会。
Femtosecond pulse characterization and compensation using multiphoton intrapulse interference phase scan (MIIPS) [Opt. Lett. 29, 775 (2004)] was rigorously tested. MIIPS was found to have 3 mrad precision within the 90 nm bandwidth of the pulses. Group-velocity dispersion measurements of glass and quartz provided independent accuracy tests. Phase distortions from high-numerical-aperture objectives were measured and corrected using MIIPS, an important requirement for reproducible two-photon microscopy. Phase compensation greatly improved the pulse-shaping results through a more accurate delivery of continuous and binary phase functions to the sample. MIIPS measurements were possible through the scattering of biological tissue, a consideration for biomedical imaging. (c) 2006 Optical Society of America.
