Abstract: A device and method for recording and reproducing holographic information, and a display apparatus are disclosed. The device for recording holographic information comprises an electro-optical regulating element, which is arranged in a light path between an object to be reproduced and a recording medium, receives an object beam scattered by the object to be reproduced, and regulates an outgoing direction and a focal distance of the object beam to irradiate the recording medium. The recording medium is configured to receive the reference beam from the light source and the object beam regulated by the electro-optical regulating element. The reference beam and the object beam form information relevant with the object to be reproduced in the recording medium. By regulating the outgoing direction and focal distance of beam with the electro-optical regulating element, it is unnecessary to rotate the recording medium for recording and reproducing the holographic information.
