DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The Cipher consists of two primary parts: a CCD imaging device and a mount. The equipment comes as
shown in Figure 2-1, with the mount secured to the body of the device.
The Cipher is a highly light-sensitive device. The Cipher sensor (CCD array) reacts to near-infrared and
visible light, and converts the received light into electrical charges. The controlling circuit converts
the entire contents of the two-dimensional array into a sequence of voltages that are processed into a
continuous analog signal. As a result, the Cipher displays real-time, contrasting gray-scale images that
correspond to the scene projected onto the focal plane of the sensor.
The main optical-electronic components of the Cipher include: an objective lens, an eyepiece, a gray-
scale CCD camera, a display, a control card, and a button control panel. The image is projected by the
output lens from the display to infinity, and the resulting image is magnified when viewed through
the day scope. As such, when the Cipher mounted in front of the day scope, it converts it into a night
vision sight.
The Cipher has a digitally-controlled adjustment of display brightness. Because the Cipher displays in-
formation on the current operating state (battery status, active function, etc.), field operation is simple
and convenient.
Manufactured for high tolerances, the Cipher has a lightweight and robust aluminum body.
A side Picatinny/Weaver rail allows an optional Armasight DT Digital Video Recorder or other equip-
ment to be installed on the Cipher.
A detachable Platform Ring makes it possible to mount additional equipment to the top of the Cipher,
such as an IR illuminator or Armasight MCS Miniature Collimating Sight.
A standard NTSC video input/output connector enables an external video display (a monitor, TV) or
video recorder to be connected to the Cipher. An external 6 VDC/1 A power source can also be con-
nected to the Cipher.
The Cipher’s quick-release mount fits any Picatinny, MIL-STD-1913, or Weaver weapon rail. The mount’s
lever-cam clamping device ensures easy, quick, and reliable mounting and removal.
The Cipher is powered by two CR 123A (2×3V) batteries.
The Cipher is shown in Figure 2-1. The ITEM NO. column of Table 2-1 indicates the number used to
identify items in Figure 2-1.
