RA
Restricted Access location (enclosed projection area).
PR
Projector.
TH
Theater (observation area).
RZ
Restriction Zone.
PD
Projection Distance.
SW
Separation Width. Must be minimum 1 meter.
For this type of setup 3 different HD shall be considered:
•
HD as discussed in
“High Brightness precautions: Hazard Distance”, page 16
, relevant for intrabeam
exposure.
•
HD
reflection
: the distance that has to be kept restrictive related to the reflected light from the rear projection
screen.
•
HD
diffuse
: the relevant distance to be considered while observing the diffuse surface of the rear projection
screen.
As described in
“High Brightness precautions: Hazard Distance”, page 16
, it is mandatory to create a
restricted zone within the beam areas closer than any HD. In the enclosed projection area the combination of
two restricted zones are relevant: The restricted zone of the projected beam toward the screen; taking into
account 1 meter Separation Width (SW) from the beam onward. Combined with the restricted zone related to
the rear reflection from the screen (HD
reflection
); also taking into account a 1 meter lateral separation.
The HD
reflection
distance equals 25% of the difference between the determined HD distance and the projection
distance to the rear projection screen. To determine the HD distance for the used lens and projector model see
chapter
“General considerations”, page 16
.
HD
reflection
= 25% (HD – PD)
The light emitted from the screen within the observation shall never exceed the RG2 exposure limit,
determined at 10 cm. The HD
diffuse
can be neglected if the measured light at the screen surface is below 5000
cd/m² or 15000 LUX.
