Abstract:
An apparatus and method for recording a micro-hologram are provided. The micro-hologram recording apparatus includes a first light source configured to emit a first light, the first light being coherent, a first optical system configured to divide the first light into a signal beam and a reference beam, and supply the signal beam and the reference beam to a location on a hologram recording medium, a second light source configured to emit a second light, the second light being incoherent and not interfering with the signal beam and the reference beam, and a second optical system configured to supply the second light to the same location as the signal beam and the reference beam on the hologram recording medium.
