A hologram projecting system includes a coherent light source for emitting a reference beam onto a real object; and an image sensor for receiving the reference beam and a scattered beam reflected from the real object, and recording a Fourier image of the real object. Also included is a modulator for receiving the Fourier image. The reference beam is passed through the modulator, and configured to interact with the Fourier image to form a virtual image of the real object. The image sensor includes an n×m pixel array, where n and m are numbers of rows and columns, respectively. The modulator includes an n×m pixel array corresponding to the n×m pixel array of the image sensor. The pixels in the n×m pixel array of the image sensor control transmissivity of light in corresponding pixels of the n×m pixel array of the modulator. |
