We here propose a new laser rangefinder, which can determine both the geometrical property and optical properties. The feature of this rangefinder is to equip an image sensor which has the ability of simultaneously detecting the position of a light and the incident angle onto the sensor. As a result, this rangefinder can determine the 3D shape of an object, which is geometrical property, and the surface reflectance of a specular object and the refractive index of a transparent object, which are optical properties.
