Tuneable Laser Diode Absorption Spectroscopy
An R&D project to develop a miniaturised laser driver and data acquisition (DAQ) system suitable for laser diode spectroscopy. This particular application was to detect presence of oxygen in hypersonic flight research. The system uses a wave-length stabilised laser diode which is modulated with various waveforms to scan required wavelength ranges. The system also controlled the laser bias and silicon temperature via thermoelectric cooler. The DAQ featured 16-bit resolution and sampling up to 25Mbps and the data was collected and stored internally on a microSD card for later analysis.
About Me
My name is Dean Vey and I'm an Electronics and Telecommunications Engineer from Australia. I have extensive experience in many areas including PCB design, embedded systems, analog and digital design, and software. I hold a number of patents and have also taken many ideas and developed them into commercial products. I also have over 10 years experience as a researcher for all manner of topics across many fields including engineering, scientific, strategic business, and marketing. I love all things electronic and my main goal is to help others get the most out of their projects.
