Abstract
Se describe un sensor fotoacústico que incluye un sistema sensor para la detección fotoacústica, por lo menos un sensor de presión de supresión de ruido y un sistema de control en conexión operativa con el sensor de presión de supresión de ruido para suprimir activamente los efectos del ruido en el ambiente en el sistema sensor. Otro sensor fotacústico incluye un volumen de medición, una fuente de energía de luz, un sensor de presión fotacústica, y por lo menos un sensor de supresión de vibración (por ejemplo, un micrófono o un acelerómetro). Otro sensor fotoacústico incluye un volumen de medición, una fuente de energía de luz y un sensor de presión fotoacústica. El volumen de medición tiene una superficie interna que es curva continuamente sobre sustancialmente la superficie interna entera con excepción de donde una ventana en conexión óptica con la fuente de luz intersecta el volumen de medición.
