Paper Abstract
Optical-resolution photoacoustic microscopy (OR-PAM) becomes a premier microscopic imaging tool in biomedicine
because it provides agent-free optical absorption information in tissues. By tightly focusing light to a spot, the fine
lateral resolution can be achieved in OR-PAM. The focal spot size is typically determined by the numerical aperture of
the used objective lens. Here, we demonstrate focus-free OR-PAM using a Bessel beam generator. In this approach, no
objective lens is required. We have photoacoustically imaged a carbon fiber with a diameter of ~6 μm, and the
measured lateral resolution was ~6-7 μm. Beneficially, the complexities of the existing OR-PAM systems can be greatly
relieved.
