- Inhalt
- The performance of optical instruments is typically limited by radiometric constraints as well by non-ideal behavior of the system, comprising noise, straylight, tolerances and aberrations. For the industrial development of optical products, these effects need to be analyzed carefully.
The lab course “Industrial applications of optics" works out two examples which focus on different aspects of such “non-ideal” optical systems.
In the first part (two sessions) we lay out and analyze a laser range finder. We start with radiometric calculations to estimate the nominal signal, the amount of straylight from the environment, and the signal-to-noise ratio. Based on these findings we set up a simplified optical design for the laser range finder.
In the second part of the lab course we will talk about the modulation transfer function (MTF) which is commonly used as a measure to assess the image quality of camera lenses (contrast, sharpness, resolution). We will have a look on influences on image quality like image aberrations, understand the meaning and interpretation of the MTF, learn how to calculate and measure MTF curves and we will take some images of test charts to evaluate them in Matlab to apply the theory and get a better understanding of MTF values and the pitfalls in measurement.
Course prerequisites:
• basic knowledge in geometrical optics and Matlab
• Mobile phone with camera
• Laptop with a running installation of Matlab

- Contents
- The intention of this seminar is to transfer the theoretical optical knowledge acquired from lectures to industrial and scientific applications.
It will cover a selection of the following topics: optical distance measurement, evaluation of the image quality of photographic lenses, the tailored design of illumination systems,
or optical particle sizing by laser diffraction.
