A mounting problem: how to get the best performance from the new APS-C sensors

This article is brought to you by: 

Imaging systems are becoming ubiquitous in modern technology; camera-lens systems are almost everywhere you look. From smartphones to self-driving cars, our world is filled with computers that rely on machine vision to record, observe, and analyse their surroundings. The number of applications is continuously expanding and their needs are wide and varied. Due to the increasingly demanding performance requirements of these machine vision systems, there is almost always a need for more resolution. 

Integrated liquid lenses in machine vision

Modulation Transfer Function (MTF)

This article is brought to you by: 

The Modulation Transfer Function (MTF) curve is an information-dense metric that reflects how a lens reproduces contrast as spatial frequency (resolution) varies. MTF curves can be used to compare the performance of multiple lenses and can help determine if an application is actually feasible with the respective lens.
