AI Technical Summary
Traditional minimum light flux super-resolution imaging is affected by optical distortion and scattering when performing depth imaging, which limits its application in biological tissues, and methods to extend the depth of focus usually sacrifice lateral resolution.
The phase modulation technique based on vector polarized light is adopted. Vector polarized light is generated by a laser, and needle-shaped or tunnel-shaped light intensity distribution is formed at the focal point using 0/π phase plates and 0-2π phase plates to extend the depth of focus while maintaining high lateral resolution.
It achieves high-resolution imaging in biological tissues with a depth of more than 1 micrometer, maintaining lateral resolution while enhancing robustness to optical distortion and scattering, and is suitable for complex biological tissue environments.
