Light beam shaping method based on microfluidic optical technology

Abstract

The invention discloses a light beam shaping method based on a microfluidic optical technology. The light beam shaping method based on the microfluidic optical technology comprises the steps that (1) diffusion and convection movement only exist between core layer fluid and wrapping layer fluid, the wrapping layer fluid surrounds the core layer fluid uniformly, the core layer fluid and the wrapping layer fluid are two kinds of fluid with different refractive indexes, and the core layer fluid and the wrapping layer fluid flow in a fluid micro cavity and jointly form a fluid optical waveguide; (2) an incidence laser emits a laser beam with a set wave length into the fluid optical waveguide, the included angle between the light beam spreading direction and the fluid flowing direction is 90+/- 10 degrees, and a light beam receiving surface receives a light beam which is output after flowing through the fluid optical waveguide; (3) light beam shaping is achieved by adjusting the flowing speed, temperature and concentration of the fluid and the types of micro fluid and controlling the diffusion process of the fluid and the space distribution of the refractive indexes. The light beam shaping method based on the microfluidic optical technology is small in loss in the light spreading process, simple in structure, convenient to manufacture and good in adjustment flexibility.

technical field [0001] The invention relates to the field of optical devices and detection systems, in particular to a light beam shaping method. Background technique [0002] Beam shaping technology includes focusing, collimation, deflection, beam splitting, coupling and other adjustments to the beam, usually by adjusting the dielectric constant and permeability distribution of the optical medium and then changing the spatial electromagnetic field distribution, such as for optical devices The adjustment of the refractive index distribution can easily realize the control of focusing, collimation, deflection, and beam splitting of the incident beam. The rapid development of microfluidic optical technology in recent years has provided us with a new method of beam shaping. The principle is to control the microscopic scale of light by controlling the flow of fluid. In view of this, microfluidic technology and systems can be introduced into the design and fabrication of fluid op...
