Description
The HS series analogue holography studios are integrated computer controlled systems that have been designed for the semi-automatic production of transmission and reflection display holograms. Analogue holograms are monochrome or “rainbow” color, but they have almost infinite resolution.
HS-2 and HS-5 analogue holography studios
Designed to produce monochrome analogue holograms:
- HS-2 – holograms in size of up to 60x40cm
- HS-5 – holograms in size of up to 100x120cm
Studios description
Each HS analogue holography studio comprises:
- pulsed holography camera with 2 or 5 Joule pulsed laser inside;
- set of mirrors for laser radiation directing;
- rig for H1 master hologram image transfer to H2 hologram copy;
- computer control of all camera operations.
Analog holograms made with Holographic Studio
Holograms made with HS-5 Studio in Magdalena Abakanowicz University of the Arts in Poznan:
Holograms made at Geola:
Holography camera works pretty much like usual photocamera with flash lamp. The difference is that in holography camera as light source is incorporated a powerful ether 2 or 5 Joule pulsed laser and holography camera has no lenses – image of holographied object goes directly to photosensitive material. That allows to achieve great 3D image resolution of 3,000 lines per millimeter. Laser light pulse duration is only 30-50 nanoseconds, so really fast processes can be memorized in 3D.
In HS-2 and HS-5 studios one can make master holograms and then transfer master hologram images to hologram copies. This holographic image transfer also is called H1-H2 transfer. Master holograms are viewable only in laser light and hologram copies are viewable when illuminated by halogen lamp or other point light source.
