Abstract
Se proporcionan una fuente de luz y un método para su uso en un sensor óptico, la fuente incluye un elemento calentado de forma resistiva. La fuente de luz incluye un circuito de potencia configurado para que proporcione un voltaje modulado por ancho de impulsos al elemento calentado de forma resistiva, donde el voltaje modulado por ancho de impulsos incluye: un factor de trabajo con un primer voltaje; y un período de impulso que incluye un período con un segundo voltaje, donde: el factor de trabajo, el primer voltaje y el período de impulso se seleccionan de modo que el elemento calentado de forma resistiva se caliente a una primera temperatura; y la primera temperatura se selecciona para que emita radiación de cuerpo negro en un intervalo espectral continuo. También se proporciona un sensor óptico para determinar una composición química que incluye una fuente de luz descrita anteriormente.
