This study continues the previous research on the precision scattering-based multi-sensor triangular laser probe architecture and develops an improved version of the multi-sensor triangular laser probe. In the design of the optical system, the Scheimpflug optical imaging principle is employed, which allows the scattered light beam to be focused and imaged on the sensor surface. The hardware architecture centers around a micro-focused laser emitter, surrounded by six Linear Charge-Coupled device (CCD) sensors arranged in a circular pattern. In order to improve the resolution and reduce the laser probe dimension, the optimal optical parameters are redesigned, and an improved optical system is constructed. Regarding the portability of the laser probe, the previously separate circuit system on the PCB board is optimized and integrated with the laser probe system. This modification has successfully been applied to the on-machine measurements.
The measurement range of the improved laser probe is ±1.75mm, with a resolution of 0.69μm and a working distance of 13.5mm. A set of LabVIEW and Arduino software have been developed for the automated. The laser probe is integrated with a three-axis motion platform to construct a non-contact measurement system. Measurements for uncertainty analysis have been performed on the surfaces of different colors and materials to compare their respective performance characteristics. Based on the calibration results, the system is applied to some practical measurements.In addition to the measurements on a three-axis motion platform, the laser probe is also installed on a machine tool for on -machine measurements. The measurement errors are compared with the results obtained from a Coordinate Measuring Machine (CMM) as a reference. The test objects include white artificial wood steeped workpieces, cylindrical workpieces, a pink artificial wood workpiece with a 30-degree inclination angle, workpieces with double- steped component, and a wooden hemisphere workpiece. At the end of the study, the non-contact measurement system is successfully applied to the reverse engineering measurement of a coin scanning.
