Topics of the department device development

The department of equipment development is concerned with the development of optical systems and processes, primarily for medical and dental applications. Here we can rely on many years of experience in public and industrial projects. Our services cover the entire value chain from the solution concept to the operational functional model.

We are looking for motivated and interested students of medical engineering, photonics, optoelectronics, physical engineering or a comparable field of study within the scope of versatile, current research and development projects

  • Internship semester
  • Bachelor Theses
  • Master Theses

Currently we can offer several works with among others the following topics:

  • Conception and realization of a lighting unit for diagnostics
  • Conception and realization of a lighting unit for therapy
  • Experimental setup and basic research on the ablation behavior of the Er:YAG laser on hard or soft tissue

For further information on current topics, please contact Dr. Karl Stock by mail or telephone.

We look forward to hearing from you!

Master thesis: Extension of a code for the simulation of light propagation under consideration of polarization

The simulation of light propagation in scattering media (e.g. biological material) has gained considerably in importance in recent years. For this purpose, a method was developed at LEMTA in Nancy (Université de Lorraine, France) without taking polarization into account. Within the scope of the work, polarization is to be added to this code and first tests of the new code are to be carried out. The work will be carried out in cooperation with the LEMTA in
Nancy.

Qualification:
Student of physics or engineering sciences
Interest in programming

Production and verification of optical phantoms based on epoxy resin

A bachelor's/master's position is offered for the further development of a process for the production of optical phantoms. The aim of this thesis is to optimize the manufacturing process of these solid state phantoms in order to be able to produce phantoms with defined optical properties (scattering and absorption) in a reproducible way. The aim is to cast different phantoms as well as to quantify their optical properties with existing measurement systems.

Qualification:
Experimental skills and innovative ideas, basic understanding of optics, knowledge of Matlab helpful.

Further development of a modular Monte Carlo simulation

A practical semester/bachelor's position is offered for the further development of the in-house framework for the calculation of light propagation using the Monte Carlo method (similar to the ray tracing methods). The focus will be on the division of the program into DLLs (or SOs for Linux): These modules shall configure themselves via an XML file.

Necessary knowledge:
C++
Helpful but not necessary knowledge: design patterns, XML, doxygen.
Additionally helpful for a bachelor thesis: compiler construction (regular expressions).

Development and test of a new type of product-related calibration routine for a measuring system

The starting point for this thesis is a measurement system developed at the ILM for the high-precision measurement of surfaces. The technology is based on chromatic confocal distance measurement.  The current system is calibrated with a customer-specific piezo motor. In the course of further development and production, the system will be made more cost-efficient and simpler. One approach is to fundamentally revise the existing calibration routine or to pursue revolutionary solutions.
The orientation of the work is very close to the product and requires a high degree of creativity in the development of new calibration methods as well as good skills in software development (Matlab,C).

Development of an optical sensor for the intraoral development of a user interface to calculate light propagation

Different solution methods can be used to calculate the light propagation in biological tissue. The choice of the optimal solution method depends on the given problem. Within the scope of this practical course, a standardized user interface will be developed, which can be used to specify the problems, start the different solution methods and analyze the results.


Requirement profile:
Programming knowledge in C/C++ and Python, knowledge in
object-oriented programming, knowledge of MATLAB

Parallel calculation of numerical simulations (Monte Carlo) with graphics cards.

Radiation transport theory is used as an approximation to calculate light propagation. Since there are only a few analytical solutions for this, solutions are determined numerically using the Monte Carlo method.
Monte Carlo simulation is a widely used method for simulating light propagation in scattering media. This relatively simple method can be parallelized well in principle. This is often necessary because long calculation times are required for precise simulation results.
The ILM has great experience in Monte Carlo simulations. Preparatory work has already been done for parallel computing on graphics cards.
The task is to implement a flexible Monte Carlo simulation for light propagation according to the theory of radiative transfer on graphics cards. As development language either CUDA or OpenCL can be used. The challenge here is to optimize the runtime.

requirements:
Interest in programming

Advantageous, but not necessary knowledge:
Optics
CUDA or OpenCL
Programming language C++ (object-oriented / procedural)
