The first, to our knowledge, miniature dual-axes confocal microscope has been developed, with an outer diameter of $10\mathrm{mm}$ , for subsurface imaging of biological tissues with $5–7\mu \mathrm{m}$ resolution. Depth-resolved en face images are obtained at $30\text{frames}\text{per}\hspace{0.17em}\text{second}$ , with a field of view of $800\times 100\mu \mathrm{m}$ , by employing a two-dimensional scanning microelectromechanical systems mirror. Reflectance and fluorescence images are obtained with a laser source at $785\mathrm{nm}$ , demonstrating the ability to perform real-time optical biopsy.
