Embodiment 1
[0051] see figure 1 , is a flow chart of the phase information training set generation method provided by the first embodiment of the present application, including steps:
[0052] Step S10, emitting a laser beam for polarization splitting to obtain first polarized light and second polarized light;
[0053] Among them, a single-frequency laser can be used to send the laser beam. Since the laser beam emitted by the single-frequency laser has the advantages of monochromaticity, good directionality, coherence, and constant phase difference, the single-frequency laser emits The laser line beam is suitable for generating interference fringes in the training set of phase information.
[0054] In this step, the laser beam is designed to be polarized and split, so that the laser beam is divided into two beams of polarized light. Specifically, in this step, a multilayer film structure can be coated on the inclined plane of the rectangular prism, and then glued into a cubic structure,...
Embodiment 2
[0067] see figure 2 , is a flow chart of the phase information training set generation method provided in the second embodiment of the present application, including steps:
[0068] Step S11, controlling the laser to emit a laser beam, and inputting the laser beam into an optical filter for filtering;
[0069] Among them, the filter adopts a neutral density filter, and the neutral density filter plays a non-selective filtering role, and the ability to reduce light of various wavelengths is equal and uniform, which is convenient for targeting The intensity of the laser beam is controlled to prevent overexposure.
[0070] Step S21, input the filtered laser beam into the half-wave plate, and inject the laser beam transmitted by the half-wave plate into the polarization beam splitter;
[0071] Specifically, for example, if the angle between the vibration plane and the fast axis (or slow axis) of the wave plate is θ when the linearly polarized light is incident, the vibration pl...
