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.
