    Abstract: The present invention provides a projector utilizing two projecting light beams to enhance the resolutions thereof and comprises a light source, a light valve, an ultrasonic medium, a piezoelectric material, and a high-frequency oscillator. The light source device is used for generating light beams to project onto the light valve to form imaging light beams. The ultrasonic medium is passed through the imaging light beams with an incident angle, the piezoelectric material is disposed on one end of the ultrasonic medium, and the high-frequency oscillator electrically connects to the piezoelectric material for generating ultrasonic waves. The ultrasonic waves from the piezoelectric material are delivered to the ultrasonic medium and the imaging light beams pass through the ultrasonic medium to form a diffraction light beam along a first direction and a transmission light beam along a second direction are produced in order to increase resolution of images projected from the projector.
