The BOTLab has three oral presentations this year at SPIE Photonics West in San Francisco:

1. Yanyu Zhao, BME Ph.D. student: Spatial Mapping of Fluorophore Quantum Yield in Scattering Media

2. Fei Teng, ECE Ph.D. student: A wearable continuous-wave optical device for continuous monitoring during neoadjuvant chemotherapy infusions

3. Sanjana Pannem and Jordan Sweer: Customized three-dimensional printed optical phantoms with user-defined absorption and scattering

Congratulations to Jordan Sweer on Summer Research Fellowship

BME Junior Jordan Sweet was awarded the prestigious Joseph Healey Distinguished Fellowship for the summer of 2015 in the BOTLab.  This will support Jordan this summer as he investigates new 3-D printing techniques for fabricating optical phantoms, and comes with a $10,000 fellowship award for stipend and research funds.

Lower noise frequency-domain measurements with new preamp

By Darren RoblyerApril 25th, 2013in Lab Updates

Raeef took new measurements with a much lower noise preamp made by the Boston University Electronics Design Facility (EDF).  Below is a drift measurement (60 repeated measurements every minute for 1 hour) with an 850nm laser diode, taken from 50-500MHz on an optical phantom with a 3mm APD.  Also shown are noise floor measurements for all 6 laser diodes.

First Frequency-Domain Measurements

Raeef helped to take out first few successful frequency-domain measurements through a tissue-simulating phantom on Dec 21, 2012.  Below is a plot showing an overlay of 60 repeated measurements over an hour (a drift test) using an 808nm laser diode and APD receiver.  There are some noise issues, but a great start!
