Diseño y simulación de un sensor óptico fotoacústico a una longitud de onda de 1550 nm

Abstract

Optical fiber has been a fundamental axis in the evolution of long-distance communications in recent years, so its characteristics have been studied to take advantage of them in different fields, such as medicine, where there has been a wide acceptance of the material for the improvement of diagnostic techniques, one of the most innovative being the photoacoustic image that allows the diagnosis of human body tissues taking advantage of the characteristics of sound and light. Therefore, this research work aimed to design and simulate a photoacoustic optical sensor at a wavelength of 1550 nm. The methodology implemented had a descriptive and quantitative approach since the performance of the sensor was analyzed based on certain parameters of the model design, being the dependent variable the power parameter since the purpose of the research was to estimate the percentage of this when transiting within the design of the photoacoustic optical sensor. Due to the nature of the research, no population or sample data were used since it was focused on a specific type of design. Using this methodology, it was possible to understand the functioning of the optical fiber as a photoacoustic optical sensor and its possible application in photoacoustic imaging, the conditions it must meet to do so, and the characteristics that must be considered to design and simulate it in the tool used in this work, Fimmwave. In this context, it is concluded that the characteristics provided by the optical fiber are influential in obtaining photoacoustic images. However, the power levels that are used need external complements to show better results.
