SQUAL
Access: Read Only
Data Type: Upper 8bits of a 10-bit unsigned integer
USAGE: SQUAL (Surface Quality) is a measure of ¼ of the number of valid features visible by the sensor in the current

frame. Use the following formula to find the total number of valid features. The values range from 0 to 144.
Number of features = SQUAL register value * 4
Since small changes in the current frame can result in changes in SQUAL, slight variations in SQUAL on one
surface is 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 typi-
cally maximized when the navigation surface is at the optimum distance from the imaging lens (the nominal
Z-height).
