THICKNESS VARIATION MEASURING DEVICE, SYSTEM USING SAME, SURFACE MICROSCOPE USING SAME, THICKNESS VARIATION MEASURING METHOD, AND SURFACE IMAGE ACQUIRING METHOD USING SAME
THICKNESS VARIATION MEASURING DEVICE, SYSTEM USING SAME, SURFACE MICROSCOPE USING SAME, THICKNESS VARIATION MEASURING METHOD, AND SURFACE IMAGE ACQUIRING METHOD USING SAME
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.
