SQUAL
Access: Read
Data Type
USAGE : SQUAL (Surface Quality) is a measure of the number of valid features visible by the sensor in the current
frame.
The maximum SQUAL register value is 162. Since small changes in the current frame can result in changes in SQUAL,
variations in SQUAL when looking at a surface are expected. The graph below shows 800 sequentially acquired
SQUAL values, while a sensor was moved slowly over white paper. SQUAL is nearly equal to zero, if there is no
surface below the sensor. SQUAL is typically maximized when the navigation surface is at the optimum distance
from the imaging lens (the nominal Z-height).
