◆ Knowledge
Introduction |
| |
|
Holography is to record
all the information of
the subject. It can not
only be as common camera
as recording the
scattered light
intensity of objects,
but also recording the
phase of the scattered
light, which is why the
original
three-dimensional image
can be reproduced. This
experiment can be
operated at bright room,
using the red-sensitive
photopolymer dry plate
reproduced by white
light as a recording
medium. When light
shines on the dry plate,
the photosensitizer is
excited and trigger the
exposure process, then a
radical initiate the
polymerization of
monomer molecules,
finally formed phase
type hologram in the
material. |
