  • Method and corresponding apparatus for reducing backlight crosstalk impact of optical assembly
    Patent number: 11438061
    Abstract: A method and corresponding apparatus for reducing a backlight crosstalk impact of an optical assembly. The method comprises: sequentially presetting two drive currents of a laser corresponding to a target wavelength channel as a first and second drive currents, respectively collecting backlight crosstalk data of the target wavelength channel to other wavelength channels, and generating a first and second crosstalk data matrix; carrying out fitting on the first and second crosstalk data matrix to acquire a crosstalk data calibration matrix; and calculating target backlight data of the target wavelength channel according to the crosstalk data calibration matrix, to calculate front light transmitting power of the target wavelength channel according to the target backlight data, thereby monitoring the optical assembly according to the front light transmitting power. The crosstalk impact can be reduced without an additional optical element, thereby improving accuracy of backlight detection and saving costs.
