Administrative Stowage - ATN PVS-7 Operator's Manual

InterMIttent operatIon. this is a defect in the image area of
the PVS-7 . Sec "flashing".
lIGHt InterFerenCe FIlter (lIF). this is a tear-protection fil-
ter for the goggle. Use of this filter will result in a slight reduction in
system gain.
MICroCHannel plate. a current-multiplying optical disk that
intensifies the electron image produced by the photocathode.
pHotoCatHoDe. the input optic of an image intensifier that ab-
sorbs light energy and in turn releases electrical energy in the form
of an electron image.
SaCrIFICIal WInDoW. a replaceable sacrificial window is sup-
plied to protect the objective lens assembly during operation in ad-
verse conditions.
SCIntIllatIon. a faint, random, sparkling effect throughout the
image area. Scintillation is a normal characteristic of the image
intensifier assembly and should not be confused with emission
points. Scintillation is more pronounced under low-light conditions.
Also called "video noise".
SHaDInG. the viewed image should be a full circle. If shading is
present, you will not see a fully circular image. Shading is indicative
of a dying photocathode and is caused by a defective vacuum seal
of the image intensifier. Shading is very dark and you cannot see an
image through it.
