  • Thickness variation measuring device, system using same, surface microscope using same, thickness variation measuring method, and surface image acquiring method using same
    Patent number: 8817274
    Abstract: Provided are an apparatus for measuring a thickness change, a system using the apparatus, a morphology microscope using the apparatus, a method of measuring a thickness change, and a method of acquiring a morphology image by using the measuring method, by which a minute thickness change may be precisely and accurately measured or a morphology image may be acquired by using an inexpensive and simple configuration. The apparatus includes a light source for irradiating beam onto a target object; a curved reflector for reflecting the beam reflected on the target object and incident onto the curved reflector; and a sensing unit for sensing the beam reflected on the curved reflector.
