+49 170 716 2482
Profile  4-year industrial experience in design of image processing
algorithms, conventional camera module, depth-sensing
camera module, and embedded Linux software.
 Learn things quickly and initiatively – expertise in the whole
camera module manufacturing process, and developed the
key algorithms to improve the optical performance and
product quality of camera module.
 Experience in developing complex system, including
algorithm design and HW/SW integration. The recent
project is 6-axis active alignment – control a 15 degree-of-
freedom machine to align two 7x7mm components and
eliminate the tilt angle between the two components to
0.03˚.
Experience
and Major
