360 Degree Circular Film and Its Projection Equipment
The 360 degree circular film and its projection equipment
were developed by Harbin Film Machinery Plant and China Film
Science and Technology Research Institute. This system was
awarded a prize of Advanced Science and Technology from China
Government
The equipment adopts the projecting form of 9 strips of 35mm
films, which is used in usual. In projecting, 9 set 35mm projectors
and 2 set 35mm 6 channels megic sound reproducer are locked
positively or and a set 16 channels megic sound reproducer
are locked positively or and a set 16 channels sound reproduction,
all running in step. Whole projection program are completed
by control-table. It makes the viewer feel as if he is participating
that 360 degree circular film made up 9 film picture and stereophony
with many channels.
The 35mm film equipment is suitable for the place of circular
film projection, which has the screen diameter within 20-25.
Main technical feature
1. All projectors, reflectors, xenon lamps and other devices
are identical. Whole images, tons are concert.
2. Projectors and reproducer are running in step and have
not
accumulated error. Sound and frames, one frame and other
frames are sync strictly in continous projecting.
3. Film of break off stop, manual stop and sync looking stop.
4. Whole projection program can be completed by projection
control table.
5. Static electrcity precipitant can remove the static
electricity
in the film and the film can be moist effectively.
6. Film cabinet is favourable to projecting film and rounding
projection.
7. Spare tone channal and amplifier can be used to broadcast
sub low frequency effect sound or other sound effect.
8. connect cable is suitable for circular film projecting
space
that the creen diameter not more than 25m.
9. 360 circular Projecting film with nine 35mm film.
10. Two 35mm tape eleven stereophony or 16 channel sound
reproduction
apparatus with many stereophony.
11. All equipment is locked by electric synchronous error
less
than 1 frame.
12. Aperture size: 17.02X23.37mm
13. Magazine capacity: 600m
14. Control:：Centralized remote control
15. Power supply: 3 phase 380/220V, Projector. 50Hz. Capacity: 150KVA
16. Effective light flux illuminace erenness and color temper
for nine projectors are concert. Effective light flux: of
a
projector over 7000 lm. Illuminace evenness: over 65%. Color
temper reture 5400+1000K Difference in color temper of the
light beam of nine projector less than 400K.
17. Focal length error for nine projectors lens less than
0.5%. |
