1.3 System Capabilities 
The SeaFLIR II Imaging System is a gyro-stabilized platform that can 
rotate a continuous 360
o 
in both azimuth and elevation.  The stabilization 
enables the internal fiber optic gyroscopes to sense and remove 
unwanted effects of motion and vibration in the elevation and azimuth 
axes.    
1.3.1 Key Features 
Key features of the SeaFLIR II Imaging System are: 
 Fiber Optic Gyroscope Stabilization – minimizing the effect of craft 
vibration and motion. 
  Continuous zoom IR and CCD optical systems – allowing 
uninterrupted viewing of the imaging scene while zooming between 
the maximum Wide and Narrow fields of view.   
  1.8X IR Optical Extender (optional) – extends target recognition 
capability and detection range. 
  IR and CCD Auto focus systems – reducing the operator workload. 
  Directional control – allows control of both azimuth and elevation 
through a full 360 degrees. 
  Ergonomic Hand Control Unit (HCU) – The SeaFLIR II Imaging 
System’s HCU is designed to be held in the right hand but its 
operation does not favor either a right or left-handed operator.  The 
pointing of the system is accomplished with the right thumb while all 
other controls such as focus and zoom are accessible with either 
hand.  The controls on the face of the HCU are normally operated 
with the left hand. 
  Video Output – black and white standard for IR, and color for CCD 
camera. 
  National Television System Committee (NTSC) – 60 hertz (Hz) color 
standard (United States) 
  Phase Alternation by Line (PAL) – 50 Hz color standard (European) 
  Closed Cycle Cooling – the IR detector is cooled by a built-in Sterling 
micro-cooler.
