Small Pixel Advantages
Digital Zoom reduces size weight and power and allows for dynamic image enhancement
Custom User-defined Region-of-Interests Allow Multiple Window Selection over FHD Scene
Small Pixel High Sensitivity Results in Better Imaging in All Seeing Conditions
NYQUIST-SHANNON
SAMPLING CRITERION
OVERSAMPLING WITH SMALLER PIXELS
Benefits of Smaller Pixel Pitch
Minimized aliasing
Negligible noise modulation
Improved Noise Equivalent Power (NEP)
Reduced false alarm rates
Lower missed detections
Deeper tracking into the noise histogram
Less detector material required for same pixel format
Use smaller, lightweight optics
Potential for lower systems cost
Correlation improved surveillance and detection range
improved optical flow and related motion processing
UNDERSAMPLING WITH LARGER PIXELS
Limitations of Larger Pixel Pitch
Increased aliasing
Signal Modulation
Diminished NEP
Increased false alarm rate
Increased missed detections
requires larger heavier optics
Potential for higher system cost
Higher integrated background signal
Tracker target dropout
