More Information
Summary:Provided are an apparatus and method for measuring the shape and thickness of a transparent object. A light projecting section that outputs beams of light to a transparent object, a light receiving sensor that receives the beams of light that have passed through the transparent object, and a data processing section that analyzes a received light signal in each light receiving element of the light receiving sensor are included. The light projecting section outputs, in parallel, output beams of light from a plurality of light sources, and the data processing section analyzes the received light signal in each light receiving element of the light receiving sensor and identifies a light source of any beam of light input into one light receiving element by using light source combination information that is stored in a storage section and that corresponds to a value of the received light signal.
