“…The discrepancy between the two adjacent arcprofiles in the overlapped region could become significant at the edge of each arc-profile measured by the stylus with a large pressure angle. According to the uncertainty analysis performed in the previous study by the authors [17], the reading of the X-coordinate in the stylus profiler is one of the main uncertainty sources. Uncertainty of the reading of the Z-coordinate in the stylus profiler, including the calibration uncertainty of the probe, could also be a major component of measurement uncertainty; it is not easy to reduce these components of measurement uncertainty.…”

“…On the other hand, the circumferential misalignment can be compensated through the circumferential stitching process-namely, a difference in the user/operator will not affect the results of the measurement. Experimental results have demonstrated that a workpiece having a diameter of 3 mm can successfully be evaluated by the proposed method [17]. The stitching linear-scan method is expected to have advantages with respect to the conventional rotary-scan method in the case where a workpiece diameter is smaller than 3 mm.…”

Attempts are made in this paper to improve the quality of the stitching between adjacent arc-profiles in the stitching linear-scan method for the roundness measurement of a cylinder in a small dimension. The data in the edge region of an arc-profile, which could be influenced by the pressure angle of the measurement probe of a linear-scan stylus profiler, are eliminated in the stitching process to improve the quality of stitching. The effectiveness of the elimination of the edge region of an arc-profile is evaluated by employing the cross-correlation coefficient of two adjacent arc-profiles as an evaluation index. Furthermore, a modification is made to the experimental setup to reduce the misalignment of a workpiece along its axial direction with respect to the scanning probe. Experiments are carried out by using the modified setup to demonstrate the feasibility of the stitching linear-scan method for the roundness measurement of a small cylinder, which is difficult to measure by the conventional rotary-scan method.

“…In a nonlinear optical process, the emission intensity has a quadratic or high-order dependence on the excitation intensity, which ensures that the signal collected out of the focal volume reaches its minimum. Thus, nonlinear optical microscopy has submicron three-dimensional spatial resolution with higher signal-to-noise ratio and less out-of-focus photobleaching, compared with traditional confocal microscopy [5][6][7][8][9]. In addition, using near infrared (NIR) excitation wavelengths also increases the penetration depth, which is particularly significant for biomedical imaging [10][11][12].…”

Real-Time Multidepth Multiphoton Microscopy Using Pixel-to-Pixel Focus-Switching

2020

Multiphoton microscopy is a well-established technique for biomedical applications, but real-time multidepth multimodal multiphoton microscopy using non-imaging detection has barely been discussed. We demonstrate a novel label-free imaging system capable of generating multimodal multiphoton signals at different focal planes simultaneously. Two spatially overlapped and temporally interlaced beams are obtained by applying cost-effective electro-optic modulator (EOM)-based fast-switching light paths. The switching beams have different divergence properties, enabling imaging at different depths into samples. The EOM is synchronized to the pixel clock from the microscope, achieving pixel-to-pixel focus-switching. The capability of the imaging system is demonstrated by performing real-time multidepth two-photon fluorescence (TPF) and second-harmonic generation (SHG) imaging of freshly excised mouse lung lobes. TPF and SHG images are acquired at two wavelength ranges. One is between 415 and 455 nm, and the other is between 495 and 635 nm. The microenvironment of pulmonary alveoli is depicted by the distributions of both elastin fibers visualized by TPF and collagen fibers illustrated by SHG. Macrophages residing inside apparent alveolar lumens are also identified by TPF, which shows that the imaging system is capable of localizing biological objects in three dimensions and has the potential of monitoring in vivo cellular dynamics in the axial direction.

In this study, three-probe error separation was developed with three chromatic confocal displacement sensors for roundness measurement. Here, the harmonic suppression is discussed first to set suitable orientation angles among three sensors. Monte Carlo simulation is utilized to test the error separation and optimize the orientation angles and off-axial distance. The experimental setup is established using chromatic confocal sensors with a precise rotary platform. The experimental results show that the measured roundness with an orientation-angle combination of (0°, 90.1°, and 178.6°) is much better than that of another nonoptimal selection (0°, 90.4°, and 177.4°). The roundness error is only 0.7% between the proposed measurement system and an expensive ultraprecision roundness meter. Furthermore, it is proven that the eccentricity distance should be decreased as small as possible to improve the measurement accuracy. In sum, this paper proposes a feasible method for roundness measurement with reliable simulations, easily integrated sensors, and an ordinary precision rotary platform.
