Correctability and long-term stability of infrared focal plane arrays
The temperature resolution of infrared focal plane arrays is limited by temporal and spatial noise. The spatial noise usually is partially removed by correction procedures. These correctionExpand
Capturing the sampling effects: a TOD sensor performance model
Preliminary results suggest that the model can be developed into a model which predicts the TOD for all kinds of sensor systems, which may include sampling effects, noise, blur and (local) image enhancement methods. Expand
