Previously, we presented an on-axis linear-response linear-motion optical scanner. While the linear design is highly desired for engineering consideration, it was still lacking the scanning speed required for imaging applications. We here present a customized profile lens (CPL), tailored for high speed performance while maintaining the advantages of a linear response on-axis optical scanner. The device was built and tested experimentally on an optical bench. The test results demonstrate precise linear response and fast scanning speed, and revealed video frame rate scanning ability. The implementation of the CPLs in laser scanning systems is promising in improving the current 3D laser scanning microscopy systems by reducing the size, error, and complexity of the system, as well as other systems unitizing high speed laser scanning technique.

“…Laser scanning microscopy, in which the sample is scanned point-by-point by a focused laser beam [1], has been widely used in many areas [2][3][4][5]. Commonly used laser scanning microscopy include confocal reflectance microscopy (CRM) [6][7][8][9], confocal fluorescence microscopy [10,11], multi-photon fluorescence microscopy (also known as two-photon fluorescence microscopy) [12,13], and second harmonic generation [14][15][16].…”

Traditional laser scanning microscopes require complex control systems to synchronize and control image acquisition. The control system is especially cumbersome in the multimodal laser scanning microscope. We have developed a novel multimodal laser scanning microscope control system based on a National Instruments multifunction data acquisition device (DAQ), which serves as both a data acquisition device and a programmable signal generator. The novel control system is low-cost and easy-to-build, with all components off-the-shelf. We have applied the control system in a multimodal laser scanning microscope. The control system has not only significantly decreased the complexity of the microscope, but also increased the system flexibility. We have demonstrated that the system can be easily customized for various applications.
