High frame rate, maximal number of pixels and high bit depth are powerful key words. Optimization for data rate is often necessary when standard interfaces, available computational power and their cost are considered.
Accuracy and speed of an edge detection
The precision of an edge detection depends on the number of pixels used to sample the edge. The maximum frame rate depends on the throughput of the optics. The final accuracy depends on factors like the residual error of distortion correction.
A respectful, constructive and direct communication is what I try to keep up with, so that the interplay between all involved people in the project stays efficient.
Measurement of optical properties
The scattering properties of a volume-scatterer can be modeled in a simulation software using specific Gegenbauer parameters. In this example I evaluated a measurement supplier to determine the Gegenbauer parameters that were used later for simulation. It was not possible to use better documented materials for systems relevant reasons of higher importance.
Initial sample testing
To independently verify the geometry of molded optics independent measurement suppliers were evaluated. The measurement results were reviewed, imported into the simulation software to evaluate the impact of manufacturing errors.
The combined contrast transfer function of objective and CMOS sensor was calculated and measured according to ISO 12233.

Statistical tolerance analysis
Statistical evaluation of an existing optics design. The data were used as base for later performance estimations of the entire system. The calculations include temperature dependent properties of the sensor.
