Test Engineer, 06/2015 to Current Google – 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, gain, full
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 chief ray angle, through focus, image
distortion, Modulation transfer function.
Provide feedback on feature
lens selection for upcoming devices.
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
