  • Publication number: 20230127319
    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.
