摘要： A detector device for mixing ratio of petrol and alcohol or the like comprising; an optically permeable column (3), one end of which has a specular layer (La), and projects to be immersed the outer surface with a mixing liquid of different kinds of components; a light emitting diode (5) placed to face the other end of the optically permeable column so that the light beams therefrom are incident on a boundary (Bo) between the optically permeable column and the mixing liquid, the light beams incident on the boundary at less than a critical angle being totally refracted, while the light beams incident on the boundary at more than a critical angle being totally reflected, the critical angle depending on a mixing degree of the mixing liquid; a photo diode (6) placed on the base plate in coplanar relationship with the light emitting diode so as to receive the light beams reflected at the boundary, or at the specular layer to go back through the column to fall thereon so as to generate an output in accordance with the light intensity received; and the column determining its lengthwise dimension and a radial dimension measured from a point of the light emitting diode to be such as to only include light beams extending from the one which is incident on the boundary at a critical angle to totally reflect only once and reflect back at the specular layer so as to directly fall on the photo diode when one component of the mixing liquid is one specified value, to other light beams which is incident on the boundary at a critical angle to totally reflect only once and reflect back at the specular layer so as to directly fall on the photo diode when the one component of the mixing liquid is other specified value.
