摘 要: | 提出一种新的用于时间序列编码放大显微系统的成像方法,主要解决了非平带光谱激光源和放大过程的非平带增益问题,避免了脉冲边沿低水平振幅的浪费。使用通信波段1550 nm波长锁模脉冲激光源,以线扫描方式对USAF-1951分辨率板第一组别刻痕实现了清晰超快成像,有效地验证光学拉伸技术中的时间-空间-频率的一一映射特性和色散傅里叶变换中的放大过程,反映了该系统其在m尺度、MHz帧率成像领域的潜力。

Abstract: | A new imaging method for serial time-encoded amplified microscope is proposed, which eliminates the impact of spectrum ripples in the non-flat spectrum source and non-uniform gain. It can avoid the waste of low-level amplitude in the pulse edge. The time-space-frequency mapping in the optical time-stretch and amplification in the Dispersion Fourier Transform are demonstrated. A 1550 nm mode-locked pulse laser is used to project the USAF-1951 resolution target line by line, which reflects the potential application in micrometer scale and ultrafast imaging field. |
