Abstract
Microcantilever arrays are valuable tools for detecting minute physical and chemical changes. Traditional microcantilever array systems, including our previous work utilizing multiple laser arrays, frequently encounter high complexity, significant costs, and increased noise caused by laser switching. This study introduces a refraction-based laser scanning system that significantly mitigates these issues by employing a rotating glass optical block for multiplex scanning. This innovative approach not only simplifies the scanning process by eliminating the need to move the laser source or the microcantilever array but also enhances scanning speed and reduces noise, as demonstrated by our experiments. Overall, this research implements a new optical scanning strategy for microcantilever array systems, which is promising due to its direct application potential as it paves the way for more accurate, high-performing, and cost-effective sensing solutions.
