2017 (English)In: Proceedings Volume 10037, Photonics in Dermatology and Plastic Surgery; 1003703 (2017) / [ed] Bernard Choi, Haishan Zeng, and Nikiforos Kollias, SPIE - International Society for Optical Engineering, 2017, article id 1003703Conference paper, Published paper (Refereed)
Abstract [en]

Here we present a handheld, implementation of Spatial Frequency Domain Spectroscopy (SFDS) that employs line imaging. The new instrument can measure 1088 spatial locations that span a 3 cm line as opposed to our benchtop system that only collects a single 1 mm diameter spot. This imager, however, retains the spectral resolution (~ 1 nm) and range (450 to 1000 nm) of our benchtop system. The device also has tremendously improved mobility and portability, allowing for greater ease of use in clinical setting. A smaller size also enables access to different tissue locations, which increases the flexibility of the device. The design of this portable system not only enables SFDS to be used in clinical settings, but also enables visualization of properties of layered tissues such as skin.
