An Indium Gallium Arsenide linear photodiode array in the 1.1-2.5 μm spectral range was characterized. The array has 1024X1 pixels with a 25 μm pitch and was manufactured by Sensors Unlimited, Inc. Characterization and analysis of the electrical and optical properties of a camera system were carried out at room temperature to obtain detector performance parameters. The signal and noise were mea...

Recent clinical studies have demonstrated that photoacoustic (PA) imaging, in conjunction with pulse echo (PE) ultrasound is a promising modality for diagnosing breast cancer. However, existing devices are unwieldy and are hard to integrate into the clinical environment. In addition, it is difficult to illuminate thick samples because light must be directed around the transducer. Conventional P...
