Abstract

We introduce a combined non-interferometric photoacoustic remote sensing (PARS) microscopy and spectral-domain optical coherence tomography (SD-OCT) system. This can provide complementary information for structural and functional imaging in biomedical applications, with intrinsic 2D registration of PARS absorption images and OCT scattering tomograms. The system includes a free-space Michelson interferometer, 147 kHz line scan spectrometer, and a 1060 nm superluminescent diode interrogation source offering up to 65 mW of power, along with a bandwidth of 65.6 nm. System validation involved imaging layered phantoms containing carbon fibers, with a PARS lateral resolution of 7 µm and OCT axial resolution of 8 µm.
