“…The laser detection technique is a nondestructive measuring tool based on the theory of laser diffraction or charge-coupled device (CCD) light projection. Laser detection techniques have been used in many industries, such as on-line detection of particle size in pharmaceuticals [19][20][21][22], production and detection of parts in manufacturing [23][24][25][26], and material determination in medicine [27]. Considering laser detection technique and its wider applications, the present study was conducted to develop an on-line analysis and monitoring system based on a high-detection sensitivity CCD laser micrometer for the quantitative visualization of droplets during the dripping process.…”

Process analysis and monitoring during the manufacturing of the dripping pills are essential. However, research on developing sensor-based technology or process analytical technology (PAT) tools to analyze and monitor the dripping process is minimal. The purpose of this work is to develop a fast and non-destructive laser detection system for quantitative visualization of droplets, which involves detecting the size of the droplet and calculating the weight of the dripping pills during the dripping process. Several factors influencing the detection performance of the detection system and the detection system capability for quantitation of the pill weight were explored. The laser detection system accurately detects the weight of the dripping pills with the coefficients of determination (R 2 ) higher than 0.99. It was also robust concerning the variation in critical process parameters and critical material attributes. Furthermore, the laser detection system was successfully applied to the production line of Ginkgo biloba leaf dripping pills to monitor the dripping pills weight. The proposed laser detection system can analyze and monitor the dripping process in dripping pill manufacturing with stable performance, high accuracy, and high efficiency.
