Coded Ptychography for Lens Free High Resolution Imaging

Description

Lens-free imaging hasemerged as a promising alternative to traditional microscopy, offering compacthardware, large field-of-view, and substantial cost and form-factor reductions.In coded ptychography, a patterned layer positioned near the sensor introducesspatial modulation that allows high-resolution phase retrieval without the needfor lenses.

In this internship,you will develop and evaluate a coded lens-free ptychographic imaging system.The focus will be on investigating different coded surface concepts and exploringptychographic reconstruction approaches to achieve improved resolution,stability, and imaging speed.

Expected LearningOutcomes

By the end of theinternship, the student will gain experience in:

• Computational imaging & lens-free microscopy
• Optical system modelling and simulation
• Ptychographic phase retrieval
• Image reconstruction algorithms and optimization
• Experimental optical coded surfaces and data acquisition
• Working with imec hardware and Python-based reconstruction pipelines

Required Skills

• Background in electrical engineering, optics/photonics, applied physics, or computer science.
• Experience in Python.
• (Optional but beneficial) Knowledge of Fourier optics, inverse problems, or machine learning.

Type of internship: Master internship

Required educational background: Electrotechnics/Electrical Engineering, Physics, Computer Science
