Non-contact scanning apparatus using frequency response separation scheme and scanning method thereof |
摘要 |
An apparatus capable of tracking a sample surface level in a z direction and oscillating a cantilever at resonant frequency by using a frequency separation scheme in non-contact mode and method thereof. The inventive apparatus includes a sensing unit for sensing a sample surface; a frequency transforming unit for transforming the sensed signal; a frequency combining unit for combining signals; and an actuating unit for actuating the sensing unit. |
