Electro-optical leveler using CMOS image sensor

A low cost, compact electronic image leveler using a CMOS image sensor is developed for level measurement. Optical system with two lenses is designed to get tilt information of total system. One lens is designed in bowl shape that can hold liquid. The gravity of the light spot on CMOS image sensor is converted into pixel coordinates proportional to the tilt angle to be measured. The reading tilt angle could be estimated with resolution better than 8 sec of arc.
