METHOD, APPARATUS AND THE SYSTEM FOR DETECTING THICKNESS OF AN OBJECT

摘要

Disclosed is a method, an apparatus, and a system for determining a thickness of an object. The system for determining a thickness of an object, comprises: a light source which irradiates light having a suitable wavelength relative to a light absorption characteristic of an object to the object; a sensor disposed to face the light source and generates an image by photographing the object irradiated with a light irradiated from the light source; and the apparatus for determining the thickness of the object using the brightness of the generated image.
