Fiber-form optics extends the high-resolution tomographic imaging capabilities of optical coherence tomography (OCT) to inside human body, i.e., endoscopic OCT. However, it still faces challenges due trade-off between probe size, resolution, and depth focus (DOF). Here we introduce a method for extending DOF in OCT with high uniformity efficiency. On basis multi-level diffractive optics, leverage multi-dimensional light-field modulation computer-generated holography (CGH) achieve precise control intensity distribution off-axis portion light.
