Abstract: A common path interferometric probe for identifying a sample includes an optical fiber, a light guide component, a GRIN lens component and a beamsplitter surface. The optical fiber outputs a light beam. The optical fiber, the light guide component and the GRIN lens component are sequentially connected. The reflection surface is disposed on the light guide component and the beamsplitter surface disposed in the GRIN lens component. When the light beam output from the optical fiber travels through the light guide component and reaches the beamsplitter surface, a part of the light beam is reflected by the beamsplitter surface to form a reference beam, and another part of the light beam passes through the beamsplitter surface to form a sample beam. The reference beam travels back to the optical fiber by undergoing reflections at the reflection surface and beamsplitter surface.

Abstract: An OCT common-path probe for identifying a sample includes an optical fiber, a first GRIN lens and a second GRIN lens. The optical fiber outputs a light beam from its end facet. The first GRIN lens is cemented to the second GRIN lens, and located between the optical fiber and the second GRIN lens. A joint surface between the first GRIN lens and the second GRIN lens reflects a part of the light beam to form a reference beam, and allows another part of the light beam to pass through to form a sample beam. The reference beam is focused on the end facet by the first GRIN lens. The sample beam is focused on the sample by the second GRIN lens, reflected by the sample to travel through the second GRIN lens, the joint surface and the first GRIN lens sequentially, and thereby focused on the end facet.

Abstract: An optical probe includes a cylindrical lens adapted to receive and transmit incident light. A light-emitting surface of the cylindrical lens is a curved end surface having a concentric ring-shaped diffractive microstructure. A working position of the optical probe is a position where a diffraction order is 1 when the incident light having a design wavelength between a first wavelength and a second wavelength passes through the diffractive microstructure. When passing through the cylindrical lens, the incident light having the first wavelength produces a diffraction effect with the diffractive microstructure and is converged at a first wavelength working position approximately the same as the working position of the optical probe with the diffraction order of 1. After being refracted by the curved end surface, the incident light having the second wavelength is converged at a second wavelength working position approximately the same as the working position of the optical probe.

When the torque rope rotates about its central axis, the rotor brings a free end of the optical fiber to scan along an arc path.
