Abstract
This paper presents a near-field scanning microscope hardware embodiment using a high-speed, low-cost oscillator circuit, comprising of an RF amplifier with positive feedback. This is compared to a conventional configuration of a vector network analyser with both the measured frequency and constant frequency modes for height measurement of a metal surface. The constant frequency mode achieved similar results but with half the sampling time.
