Abstract
In this work we propose a new low-cost and compact optoelectronic system for optical mammography trials based on the use of low-cost semiconductor lasers and Si photodetectors. This system is completed using a versatile electronic architecture based on COTS (Cost-Off-The-Shelf) telecom components and techniques. The system is also designed for experimental studies on the dependence of the modulation frequency and the optimum signal to noise ratio (SNR). Results presented in this paper show the effect the modulation frequency and index has on the phase of the signal when passing through a commonly used scattering medium.
