HOLOGRAPHIC RECORDING DEVICE AND HOLOGRAPHIC RECORDING METHOD

Title:

HOLOGRAPHIC RECORDING DEVICE AND HOLOGRAPHIC RECORDING METHOD

Document Type and Number:

WIPO Patent Application WO/2016/138723

Kind Code:

A1

Abstract:

A holographic recording device and a holographic recording method. The holographic recording device comprises an object imaging unit and a light modulation unit. The object imaging unit comprises a cavity, the interior of which is a reflecting surface and which is used to accommodate an object (1), and the light modulation unit is used to generate incident light and reference light interfering with the incident light and to direct the incident light to the object imaging unit. The cavity is provided with an imaging hole (7) for imaging the object (1), and at least one light incident hole (8) through which the incident light can enter the cavity to irradiate the object (1) so that the object (1) is imaged at a position outside of the cavity corresponding to the imaging hole (7). Image light generated during the imaging of the object (1) interferes with the reference light at the position, in order to record an image plane hologram. The object imaging unit is neither limited nor affected by lens manufacturing processes, so that aberration can be reduced effectively and imaging quality can be improved. In addition, one-step holographic recording can be effectively and conveniently realized.
