Describe how light passes through the ANVIS.
OPMPFE
Objective Lens (inverts image, minus blue filter)
Photocathode (changes photons to electrons)
Microchannel Plate (multiplies electrons)
Phospher Screen (electrons to protons, creates the lighted image)
Fiber Optic Inverter (inverts the image)
Eyepiece Lens (allows the eye to see the image)
Warnings, along with fires, and emergencies without associated W/C/A messages are located in the
_______ section.
Red
Yellow
Blue
Green
Red
What is Automatic Brightness Protection (ABC)?
ABC automatically adjusts microchannel plate (MCP) voltage to maintain image brightness at preset
levels by controlling the amount of electrons that exit the MCP.
ABC is to protect the wearers vision, not to protect the goggles.
Within the FRCs, Cautions are in the ________ section.
Red
Yellow
Blue
Green

What is Bright Source Protection (BSP)?
Reduces the voltage to the photocathode when exposed to bright light sources.
This protects the goggles from damage and enhances its life (however, it lowers resolution).
Exposure to bright light sources could result in damage to the photocathode, MCP, or the operator's
eye.
Advisories and Annunciators with an associated emergency procedure are in the ______ section.
Red
Yellow
Blue
Green
What is an operational defect?
Defects that relate to the reliability of the image intensifier and are an indication of instability. An
operational defect is an immediate cause for rejection.
Mission Equipment emergency procedures without associated W/C/A messages are in the ______
section.
Red
Yellow
Blue
Green

What are the operational defects?
FESE
Flashing, Flickering, or Intermittent Operation
Edge Glow
Shading
