Claims

[Scope of utility model registration request]

a beam splitter that splits a laser beam oscillated from a laser light source of pulsed laser holography; and a first beam splitter that is split by the beam splitter.
A single-beam type uses a beam expander, a lens, and a subject to pass through a beam expander, reflects it on a half mirror, and photographs it on a first photographic plate. A pulsed laser holographic system characterized in that it is of a two-beam type, in which the second photographic plate is irradiated with the laser beam, and the second photographic plate is irradiated with laser light that has passed through a half mirror in the one-beam type. Measuring device.
