The Technical University of Denmark has an open 2.5-year Postdoctoral Researcher position as part of the Grand Solutions project, “AINDT”. AINDT aims to deliver industrial mid-IR (MIR) OCT scanners that combine ultra-high resolution sub-surface optical imaging with AI-powered real-time defect and layer thickness detection. Hereby AINDT will enable in-line non-contact, non-destructive test (NDT) of highly scattering materials and advanced components critical for today’s society.
This includes Multilayer Ceramic Chip Capacitors (MLCCs) essential to modern high-volume electronics, advanced Multi-Material 3D Printed Ceramic (MMPC) -based antenna modules as key elements for the coming e-health environment and protective multi-layer coatings, all of which remain challenging for conventional inspection techniques.
The interdisciplinary nature of the project requires that you enjoy working with both academic and industrial partners.
Responsibilities and qualifications
You will explore novel methods for up and down conversion of MIR optical light in the 3-4 µm and 6-8 µm range respectively. A first part involves pulsed, synchronous upconversion of a supercontinuum (SC) light source which eliminates the need for expensive, noisy, and cryogenic cooled MIR detectors. Upconversion is already a strong and internationally recognised scientific competence in our research group and used in numerous MIR applications such as MIR spectroscopy for biopsy screening and environmental gas sensing. Secondly a system for down conversion of a 200 nm broadband, <20 fs pulse laser, centred at 1030 nm is developed transferring it spectrum to the 6-8 µm region. Hereby a novel, low noise light source is produced.
The project will be conducted in close collaboration with NKT Photonics that supply a short pulse laser and NORBLIS developing the complete OCT system.
Key activities
Qualifications
As a formal qualification, you must hold a PhD degree (or equivalent), with a good understanding of solid-state light sources, second-order nonlinear optics (DFG and SFG). The project will include both experimental and theoretical work. Knowledge of data acquisition, electronics and signal processing is preferable.
Personal qualifications
To become successful, you must be enthusiastic and feel strongly for optical engineering and excellent designs, be able to combine theory with practical and systematic execution and enjoy sharing your passion with your colleagues. You should have a creative and positive mindset and thrive in an informal and cross-functional environment.
You will have your workplace at the Technical University of Denmark, Risø Campus. Our research group, “Optical Sensor Technology” has a long tradition for applied optics and strives to implement new scientific solutions to real world problems within healthcare and in support of a greener society. A passion that you should share.
During the project you are expected to publish and present the findings, and to coordinate the work with project academic and industrial partners.
