A Near-Field mm-Wave Imaging Technique for Skin Cancer Detection

Student thesis: Master's Thesis

Abstract

The near-field imaging technique proposed aims to replacing bulky and expensive imaging methods using femtosecond lasers and optical detectors. The result is a hand scanner based on small integrated circuits that could produce a synthetic image based on skin properties when affected by cancer. The focus of this thesis is in validating the method used and the analysis of systematic errors involved. The results will be used in developing an integrated circuit operating at mm-Waves. It consists of a transmission line with taps for a peak detector array, an integrated antenna, an oscillator followed by a power amplifier with controllable power. The outputs of the peak detectors are read by an ADC array producing a 10 bit output as a measure of the DC voltage of the peak detector. The thesis concerns the design of the transmission line, peak detector and integrated antenna. The resolution obtained is better than the dimensions of the integrated antenna. This is a consequence of near field operation of the scanner.
