Laser scanning microscopy as a versatile platform: imaging based on nonlinear and ultrafast effects

Abstract

The nature of scanning image acquisition greatly facilitates incorporation of various contrast signals for imaging and integration with techniques in signal processing. In this study, we are reporting imaging modalities and techniques based on nonlinear optical and ultrafast effects that are excited by ultrafast laser. Additionally, the use of signal processing electronics allows signal conditioning techniques, such as dithering, lock-in detection,Ö etc, to be employed so that better signal to noise ratio can be resulted and special features in imaging can be emphasized.
