Optionally, in an embodiment of the present application, as shown in fig. 2, the process of determining the plurality of first evaluation parameters for evaluating the optical performance index of the optical transceiver module in step 101 may include the following steps:

1011. Carrying out holographic imaging on the optical transceiver module by utilizing optical coherence imaging equipment so as to obtain a holographic image of the optical transceiver module;

in this step, optical coherence imaging is a technique of imaging using the interference principle of light. In step 1011, the optical transceiver module is holographically imaged using an optical coherence imaging device, i.e., light is irradiated onto the module, and then a holographic image of the module is acquired. The hologram image may contain detailed information about the light transceiving integrated component, such as the spatial frequency of the interference fringes, the shape of the interference fringes, the period of the interference fringes, the intensity distribution of the interference fringes, and the like.

In practice, an optical coherence imaging device, such as an Optical Coherence Tomography (OCT) device, may be used. Light is irradiated onto the light receiving and transmitting integrated component, and interference signals of the light are captured through the detector. The captured interference signals are then processed and analyzed to generate a holographic image of the optical transceiver component. The holographic image may display information of internal structure, surface morphology, defects, etc. of the assembly.

1012. Performing image processing on the holographic image to extract key parameters for calculating the plurality of first evaluation parameters;

In step 1012, the obtained holographic image of the optical transceiver module is subjected to image processing to extract key parameters required for calculating the plurality of first evaluation parameters. Image processing may include techniques such as image enhancement, noise filtering, edge detection, etc., with the aim of extracting image features that are related to the evaluation parameters.

When the key parameters include at least the spatial frequency of the interference fringes, the shape of the interference fringes, the period of the interference fringes, and the intensity distribution of the interference fringes, step 1012 may specifically include the following steps:

image preprocessing: first, the hologram image is preprocessed to improve image quality. Common pre-processing steps include denoising, contrast enhancement, edge detection, and the like.

Spatial frequency extraction of interference fringes: the holographic image may be converted to the frequency domain using a frequency domain analysis method such as fourier transform or wavelet transform. In the frequency domain, the spatial frequency of the interference fringes can be extracted by looking for the frequency peaks or frequency distribution of the interference fringes.

Shape extraction of interference fringes: the shape of the interference fringe can be extracted by an image processing algorithm such as edge detection. Common edge detection algorithms include Sobel operator, canny edge detection, etc.

And (3) extracting the period of interference fringes: by calculating the period of the interference fringes, the phase change condition of the interference fringes can be known. The period of the interference fringes can be determined using autocorrelation functions or correlation peak detection, etc.

Extracting the intensity distribution of interference fringes: by calculating the pixel value or the gradation value of the interference fringe, the intensity distribution of the interference fringe can be obtained. The intensity distribution of the interference fringes can be extracted using pixel value statistics, histogram equalization, or gray level segmentation, etc.

The above steps may be used in combination to select the appropriate image processing algorithm and analysis method according to the specific image characteristics and requirements. By extracting the spatial frequency, shape, period and intensity distribution of the interference fringes, the interference effect of the optical transceiver module can be evaluated and analyzed.

1013. And carrying the key parameters corresponding to each first evaluation index into a calculation formula of each first evaluation index so as to calculate a plurality of first evaluation parameters.

In step 1013, the key parameters extracted in step 1012 are calculated according to the calculation formula of each first evaluation index, so as to obtain a plurality of first evaluation parameters, and the specific calculation process can be seen in the following embodiments.

Through steps 1011, 1012 and 1013, key parameters can be extracted from the hologram image of the optical transceiver module, and a plurality of first evaluation parameters can be calculated according to a calculation formula. These evaluation parameters can be used to evaluate the optical performance of the optical transceiver module and provide references for performance optimization and improvement.

Optionally, in an embodiment of the present application, the key parameters include at least a spatial frequency of the interference fringe, a shape of the interference fringe, a period of the interference fringe, and an intensity distribution of the interference fringe; the plurality of first evaluation parameters includes: optical transmission distance, optical wave phase difference and optical loss rate;

step 1013 may specifically include:

optionally, the spatial frequency of the interference fringes is substituted into a calculation formula of the light transmission distance: light transmission distance = spatial frequency of interference fringes × pixel size of holographic image/wavelength of light field to calculate light transmission distance;

wherein the pixel size of the holographic image may be obtained by: when capturing a hologram image, a camera or video camera whose pixels are known is used for capturing. The pixel size is commonly specified in the specifications of cameras. If a scanning mode is used to generate the holographic image, the pixel size may be obtained by the specifications or scanning parameters of the scanning device.

Wherein, the wavelength of the light field can be obtained according to the characteristics of the light source: if a monochromatic light source is used, the wavelength of the light field can be obtained by consulting the specifications of the light source or measuring with a spectrometer. If a white light source is used, the white light can be decomposed into light of different wavelengths by a grating or other light splitting device, and then the light field wavelength at each wavelength can be obtained by using a monochromatic light source.

For example, suppose there is a hologram whose interference fringes have a spatial frequency f, the pixel size of the hologram is p, and the wavelength of the optical field is λ. The light transmission distance d may be calculated using the following formula:

d＝f*p/λ；

assuming that the spatial frequency of the interference fringes is 0.1 lines/pixel, the pixel size of the holographic image is 1 micron/pixel, and the wavelength of the optical field is 633 nanometers. To calculate the light transmission distance.

Light transmission distance = 0.1 lines/pixel x 1 micron/pixel/633 nm = 0.000158 microns/nm;

thus, the light transmission distance is 0.000158 μm/nm, depending on the given parameters.

It should be noted that this calculation formula is based on an ideal case, and it is assumed that the spatial frequency of the interference fringes is constant. In practical applications, other factors, such as diffraction, transmission loss, etc., of light are also considered. Therefore, the actual light transmission distance may deviate. This embodiment provides only a basic calculation method, and in particular needs to be adjusted and optimized according to practical applications.

Optionally, substituting the shape of the interference fringe and the period of the interference fringe into a calculation formula of the optical wave phase difference: optical wave phase difference=2pi (shape of interference fringe/period of interference fringe) to calculate optical wave phase difference;

the shape and period of the interference fringes are key parameters extracted from the holographic image.

For example, assume that the shape of an interference fringe extracted from a hologram image is s and the period of the interference fringe is T. The optical wave phase difference Δφ may be calculated using the following formula:

Δφ＝2π*(s/T)；

the shape of the interference fringe extracted from the hologram image was assumed to be 0.5 radian, and the period of the interference fringe was 10 μm. To calculate the phase difference of the light waves.

Optical wave phase difference=2pi (0.5 radians/10 microns) =0.314 radians/micron;

thus, the optical wave phase difference is 0.314 radians/micron, depending on the given parameters.

It should be noted that this calculation formula assumes that the shape and period of the interference fringes are constant. In practical application, factors such as variation and distortion of interference fringes are also considered. Therefore, the actual phase difference of the light waves may deviate. This embodiment provides only a basic calculation method, and in particular needs to be adjusted and optimized according to practical applications.

Optionally, substituting the intensity distribution of the interference fringes into a calculation formula of the optical loss rate: optical loss rate = 1-contrast/amplitude difference to calculate the optical loss rate;

wherein the contrast is calculated from the intensity distribution of the interference fringes, and the amplitude difference is determined by comparing the intensity differences of the input light and the output light.

For example, assuming that the contrast calculated from the intensity distribution of the interference fringes is C, the intensity of the input light is i_in, and the intensity of the output light is i_out. The light loss rate L can be calculated using the following formula:

L＝1-C/(I_in-I_out)；

the contrast calculated from the intensity distribution of the interference fringes was assumed to be 0.8, the intensity of the input light was 10mW, and the intensity of the output light was 8mW. To calculate the optical loss rate.

Optical loss ratio=1 to 0.8/(10 mW to 8 mW) ≡0.6;

thus, the optical loss rate was 0.6 according to the given parameters.
