Abstract

Se proporciona un tazón colector para acumular gotitas de líquido desde un filtro, como un contenido líquido. El tazón colector incluye un prisma vertical transparente. El prisma vertical transparente incluye una cara que forma una superficie transparente vertical que está orientada contra un contenido de la sección. La cara puede proporcionar un primer ángulo de reflexión total cuando el contenido de la sección es un tipo de gas y un segundo ángulo de reflexión total cuando el contenido de la sección es el contenido líquido. Una fuente de luz puede emitir un haz de luz incidente sobre la cara en un ángulo de incidencia. El ángulo de incidencia genera reflexión del haz de luz encontrando el receptor de luz, cuando la cara tiene el primer ángulo de reflexión total y genera refracción del haz de luz pasando por alto el receptor de luz, cuando la cara tiene el segundo ángulo de reflexión total.
