In this study, we present a novel approach for the measurement of modulation transfer function (MTF) of fisheye lenses. Fisheye lenses are known for their extreme wide-angle views, and pose unique challenges for MTF testing due to their complex optical properties, and the need for a large space for testing. The objective of this research is to devise a compact testing setup that enables MTF analysis of fisheye lenses within a compact controlled environment. To achieve this, we designed a setup using an adapter lens that reduces the required testing space from a full room to a compact 0.5m × 0.5m × 0.5m enclosure. We show an MTF analysis on one fisheye lens within this controlled environment.
