Fig. 1.

Scanning measurements are achieved using a probe with integrated motion tracker. (a) Screen capture of the real-time imaging (Video 1) of a $12\mathrm{cm}\times 12\mathrm{cm}$ area of phantom with embedded inclusion (left) while DOSI handpiece is scanned across phantom surface (right). The probe with attached source optical fiber, detection optical fiber, and HTC VIVE Tracker is shown on the right. The HTC VIVE Lighthouse was placed approximately 1 meter above the scanning surface (Lighthouse not captured in image frame). (b) Bottom view of a probe with an APD port and two options to adjust position of the FDPM and CW source optical fibers. CW light is collected using an optical fiber passed through the APD case. Dimensions are in inches. The VIVE tracker is mounted on top of the APD module (Video 1, MP4, 10.5 MB [URL: https://doi.org/10.1117/1.JBO.26.8.085002.1]).
