The OMCI system, shown as (a) a photo of the imaging hardware, including an optical imaging assembly containing a camera on top and the source unit at the bottom, an articulating data acquisition laptop, and foot-pedals and motor controllers for applying mammography-like compression, height adjustment and rotation. In (b), we also include a detailed schematic depicting the components in the OMCI optical imaging subsystems. The continuous-wave (CW) imaging subsystem includes two CW lasers (CW-L1/2), lenses (L1/2), a dichroic mirror (DM), a digital micromirror device (DMD), an expansion lens (EL), a reflection mirror (RM), and the measuring camera (CMR). The frequency-domain (FD) imaging subsystem consists of two radio-frequency-modulated lasers (RF-L1/2), a bifurcated fiber bundle (BF), collimation lenses (CL1/2), a focusing lens (FL), dual-axis galvo mirrors (GM-X/Y), and a detection fiber (RF-DF) located above the imaging target. The structured light imaging (SLI) subsystem consists of two webcams (W1/2) and a pattern illumination projector (PR).
