APPARATUS FOR RECORDING HOLOGRAM AND MEASURING DIFFRACTION EFFICIENCY OF RECORDED HOLOGRAM

摘要

The present invention provides an apparatus for recording a hologram and measuring a diffraction efficiency of the recorded hologram, comprising: a table (10) having a predetermined vertical height from ground; an optical source unit (20) including an optical source (21) and a beam splitter (28); a mirror unit (30) including a first mirror (32) and a second mirror (36); a first detector unit (40) which is positioned on the table (10) to face and be apart from the second mirror (36) by a predetermined distance; a second detector unit (50) which is positioned from the beam splitter (28) in a diagonal direction with a predetermined distance between them and includes a third mirror (52) and a second detector (54); a hologram record material housing unit (60) which includes a left-right moving unit (62) and a hologram record material housing (64) which is moved a predetermined distance in a direction of right and left by the left-right moving unit (62); a third detector unit (70) which includes a third detector (72) which faces the first mirror (32) with the hologram record material housing (64) between them; a spectrometer (80) which includes a fifth detector (82), an integrating sphere (84), a fourth detector (86), and an auxiliary optical source (88), wherein the integrating sphere (84) includes a reflector (85) on an inner surface thereof, and is positioned to face and be apart from the other side of the hologram record material housing (64) by a predetermined distance; and an analysis control device (90) which is installed on the other portion of the table (10).;COPYRIGHT KIPO 2016
