06/2015 to 06/2017
Test EngineerGoogle － Mountain View, CA
Daily Task includes:
Characterize image sensors and modules which includes: Capturing raw image in controlled
environment, calculate performance metric using an in house algorithms, compare sensors
across various test (Blooming, photon transfer, quantum efficiency, Dark current.
Perform power supply noise rejection test which focuses on determining the noise on the
power supply on image taken with a camera module by sweeping frequencies at a
predetermined noise level and capture images.
Focused on taking consistent data to help track sensor performance from different
vendors/technologies.
Participate on sensor selection from different vendors/selection based on consistent
measurement.
Test and validate fully integrated mobile phone camera and use Imatest (Image Quality
Software) to determine performance in low light condition, auto white balance accuracy,
focus speed and sharpness on android and/or IOS application.
Perform multiple test on camera lens which consist of checking: lens MTF(Modulation
transfer function) chief ray angle, through focus, image distortion.
Provide feedback on feature lens selection for upcoming devices.
Perform lens flare performance in which we check the flare ratio on various angle anfd
tilt positiomn.
Perform Power supply rejection ratio (PSRR) measurements to determine the effects of
noise on the power supply on image taken with a camera module or evaluation board by
sweeping frequencies at a predetermined noise level and capture images.
Analyst images to determine the ratio of temporal noise to raw temporal noise.
Perform various temperature test of image sensors in a controlled thermal chamber with
fix integration time and different gain level increment to evaluate noise level.

Sr. Engineering TechnicianTopcon Positioning Systems － Livermore, CA
Mainly responsible for performing various functionality tests from board level to finish
unit level.
Tests include and are not limited to:
For 3D mapping systems units:
Checked first all system components and wiring before performing tests including checking
and configuring the rotating Long Range Lidar sensor for visual details, IMU (Inertial
Measurement Unit) and for positional accuracy and reliability, GNSS receiver frequencies,
and wheel encoders
Calibrated the 360 spherical cameras to work with the rest of the system.
For machine control:
Performed various tests to ensure that automation software is functioning properly
checking LCD backlight, valve current output, Can Buses, Sounds systems, RS232
communication, and loads the final firmware.
For Application (User Interface)
Performed an extensive GUI testing base on the functionality requirements.
Opened defects and classified them by priority.
Performed regression testing after defects were fixed.
Prepared and distributed the daily test status reports.
03/2005 to 09/2005
Test/Debug TechnicianIBM － San Jose, CA
As a Test/Debug Technician, I received defective drives from customers and performed the
