  • Publication number: 20150049372
    Abstract: A free-space dynamic diffractive projection apparatus comprises a laser light source element, a dynamic diffractive element, a control element, and a signal output element. Based on a pattern signal outputted from the signal output element, the control element controls the laser light source element to emit a color beam, and controls the dynamic diffractive element to perform real-time signal modulation so as to generate different dynamic diffractive grating distributions in a specific period. Accordingly, the color beam passes through the dynamic diffractive element to produce the pixels defined by the pattern signal in a specific space. The control element controls the dynamic diffracting element to be quickly switched to display each pixel, so that each pixel is projected on a corresponding position in a specific space to form a two-dimensional geometric image.
