Night Sight (AN/TAS 4A).
The Night Sight (Figure 1-1) is a passive device.
It receives
infrared energy from the target area.
The infrared energy is
converted to electrical signals, and these signals are then converted
to visible light. This visible light is presented to the gunner to
permit real time tracking or observation of a target.
The night sight enables the operator to track targets in darkness,
daylight, and degraded field conditions.
The night sight operates
using a battery power conditioner or vehicle power conditioner, has
narrow field-of-view (NFOV)(12X) and wide field-of-view (WFOV)(4X),
uses a closed cycle cooler to cool infrared (IR) detectors, and has
adjustments to aline the night sight with the optical sight. Listed
in the figure are the external controls and assemblies.
