摘要:
A distance measuring apparatus includes: a number of simple lenses in substantially the same shape, on which light that has come from the object of range finding is incident; and an image capturing section, which has a number of image capturing areas and which captures the images of the object of range finding that have been produced by the respective simple lenses on their associated image capturing areas. The lens surfaces of each lens that are opposed to the object of range finding and the image capturing section, respectively, are only aspheric refracting surfaces. In each of the simple lenses, the paraxial radii of curvature R1 and R2 of the lens surfaces that are opposed to the object of range finding and the image capturing section, respectively, and its focus length f satisfy the condition −2.4≦f(1/R1+1/R2)≦−0.6.
