Abstract
Disclosed herein is an apparatus for recording a hologram. The apparatus for recording a hologram according to the present specification may include a light source unit configured to illuminate an object with light, a housing having a predetermined shape and configured to block outside light, a coupling unit to which a recording medium having a photopolymer composition applied thereto is coupled, a lens unit positioned at a front surface of the housing and configured to form an image on the coupling unit, a filter unit, a backlight unit, and a controller.
Claims10
An apparatus for recording a hologram, comprising:
- a light source unit configured to illuminate an object with light;
- a housing having a predetermined shape and configured to block outside light;
- a coupling unit to which a recording medium having a photopolymer composition applied thereto is coupled;
- a lens unit positioned at a front surface of the housing and configured to form an image on the coupling unit;
- a filter unit positioned between the lens unit and the coupling unit and configured to block at least one wavelength region of a plurality of wavelength regions included in object light reflected from the object in response to a control signal;
- a backlight unit positioned at a rear surface of the coupling unit and configured to illuminate the coupling unit with reference light;
- and
- a controller configured to output a signal to control the light source unit, the filter unit, or the backlight unit.
