Holography in the Bragg type AOSLM

摘要

The pulsed laser electro-holographic system was realized by feeding the calculated fringe data of an artificial object into the Bragg regime AOSLM(acousto-optic spatial light modulator).In the CGH (computer generated hologram) for the pulsed laser electro-holograpic system, we adopted single-sideband holography for the selective reconstruction of the real or the virtual image by the specific characterization of the AOSLM in the in-line holography and made use of the function that removes the noise and reduces the calculation time in the Fresnel and the image hologram of the AOSLM with the limited bandwidth.
