Optical Test Engineer H/F

Within the Core equipments team, you contribute to the development, characterization and calibration of current and future space camera systems. This position covers optical engineering, electro-optical characterization, image processing and experimental work. You will take ownership of camera characterization benches, from their development and improvement to the execution and analysis of test campaigns. Beyond measuring camera performance, the objective is to understand system limitations and propose improvements to both the test facilities and the camera itself.

Job Description

• Definition of calibration procedures and camera performance models.
• Characterization of optical performance, including PSF, MTF, focus, field dependence, distortion, vignetting, boresight.
• Characterization of radiometric and detector performance, including linearity, sensitivity, dynamic range, read noise, dark current, DSNU/PRNU, gain and SNR.
• Characterization under representative operating condition, including variations in illumination, exposure, focus and temperature.
• Development of automated acquisition and data-analysis tools.
• Analysis of unexpected or limiting performance, identification of its origin, and design of experiments to investigate it.
• Review and improvement of existing test methods to increase accuracy, repeatability and/or efficiency.
• Use of characterization results to provide feedback on the camera architecture, including optical design, detector operating conditions, calibration strategy, mechanical alignment, acquisition parameters and image-processing approaches.
