PROBLEM TO BE SOLVED: To provide a speckle suppressing system and method in the laser projection system. SOLUTION: The speckle suppressing laser projection system is the optical projection system consisting of a radio frequency oscillator, a semiconductor laser, and an optical projection system. The radio frequency oscillator injects the radio frequency signal in the semiconductor laser, and generates multi- wavelength output, and the optical projection system projects an image using the multi-wavelength output of the semiconductor laser. |
