(a) System schematic detailing custom fiber bundle, enabling three channel (confocal and dual-channel non-confocal) light collection. ADD: Airy disk diameter, APD: avalanche photodiode, DM: deformable mirror, FM: fold mirror, LP: linear polarizer, MMF: multimode fiber, PBS: polarizing beam splitter, PC: polarization controller, PM: polarization-maintaining, PMT: photomultiplier tube, QWP: quarter wave plate, SLD: superluminescent diode, SMF: single mode fiber, TIA: transimpedance amplifier, and TFB: trifurcated fiber bundle. End-on view of fiber bundle that displays packing of 19 MMFs with 50 μm core diameter. (b) Rendering of probe displaying lightweight and compact skeleton design with the beam path shown in red. Dimensions: 12.3 cm x 5.3 cm x 14.4 cm. (c) Photograph of enclosed probe ready for handheld operation.
