Front 6

020-6

How does the LLTV camera allow the user to see in conditions much too dark for the human eyeor DTV camera?

Back 6

The light from a beam splitter strikes a photocathode in an image intensifier, dislodging electrons that areaccelerated across an electrostatic field. The electrons gain energy as they are accelerated across the electricfield, then they strike another photocathode, releasing more electrons and repeating the process in eachstage of the image intensifier device until they are directed onto a phosphor screen (like a small, green TVscreen).

Front 11

020-11

If the laser is fired when aimed at a masked area, what will happen when it passes that maskedarea?

Back 11

When the laser is clear of the masked area it will automatically resume firing, providing that the sensoroperator has kept the laser fire trigger pressed during the masking event.

If the TU temperature is below –10 °C at power-up, what will occur?

Back 12

A blanket-type heater mounted to the LRD housing is energized to warm the laser chassis.

Front 13

020-13

If the EU receives an LOS rate command, what will it do?
