Near Infrared Imaging System, Barbara Adu-Baffour

Honors Scholar Theses

This senior project is to design and fabricate a near infrared imaging system using laser diodes for imaging biological tissues. The device will have three major sections comprising the signal source, detection and data analysis sections.

In the source signal section, a circuit would be designed and built which will contain two laser diodes with different wavelengths (780nm and 830nm). Each of the two laser diodes will modulated at different frequencies to enable a spatial coding system. The detection section of the device will have an optical detector channel which will be designed to detect signals from all the laser …
