Based on the beam spread and the point spread functions, the quantitative relationships between imaging distance and imaging quality and target distance, receiver field angle, facula size and light power in ordinary sea water was calculated for a synchronous scanning underwater laser imaging system. The results show that the imaging distance can be effectively extended and the imaging quality can be improved by compressing the laser beam, using a receiving angle with a narrow visual field, and adding a suitable laser light power. However, the improvement of the above properties is no longer visible after the light power of the laser has reached a certain value.
