Lock-in-detection-free line-scan stimulated Raman scattering microscopy for near video-rate Raman imaging

Abstract

We report on the development of a unique lock-in-detection-free line-scan stimulated Raman scattering microscopy technique based on a linear detector with a large full well capacity controlled by a field-programmable gate array (FPGA) for near video-rate Raman imaging. With the use of parallel excitation and detection scheme, the line-scan SRS imaging at 20 frames per second can be acquired with a 5-fold lower excitation power density, compared to conventional point-scan SRS imaging. The rapid data communication between the FPGA and the linear detector allows a high line-scanning rate to boost the SRS imaging speed without the need for lock-in detection. We demonstrate this lock-in-detection-free line-scan SRS imaging technique using the 0.5 μm polystyrene and 1.0 μm poly(methyl methacrylate) beads mixed in water, as well as living gastric cancer cells.
