Modulation transfer function

Quick MTF checks the quality of images taken with an imaging device, letting you test the device's performance in different conditions and settings. This enables you to make an informed decision about whether the device meets your needs.

Quick MTF lets you test the quality of digital images. It has a precise computing engine and intuitive user interface that is easy to use without special training. Simply open the test image with Quick MTF and select the target region.

IR, also infrared, is light just outside of the visible range. The name “infrared” comes from the Latin prefix “infra”, meaning “below” and the word “red”. The word directly means "below red", which is exactly what infrared is in terms of its frequency.

Far-infrared, on the other hand, cannot be registered with any of the human senses. The frequency is used in remote control technology to transmit information. The most popular devices using this technology are TV remote controls.

The infrared light ranges from near- to far-infrared, first being closer to the visible light and the latter - microwaves. Near-infrared is what we know as heat, so although we cannot see it, we can most certainly feel it.

The technology is also used in night-vision devices. It allows users to see in the dark, without being seen themselves - at least not without special equipment. At Wiseled, infrared is used in our Xtruder RAVEN - an aid to driver’s vision enhancement.

The trial version of Quick MTF allows you to perform 40 tests for free. You can start right now by taking a picture with your device and downloading the application here.

The test table contains slanted-edge areas. By analyzing such areas, Quick MTF can calculate the device's resolution, chromatic aberration, and noise. The technique is described in the ISO 12233 standard and fully implemented in Quick MTF. Image analysis using the modulation transfer function (MTF) provides more accurate and objective information on the resolution than many other approaches. MTF modelling through slanted-edge analysis is one of the most effective techniques.

Quick MTF can be used to check virtually any imaging equipment; it is successfully used for testing the quality of lenses, cameras, medical imaging devices, night vision systems, microscopes, surveillance systems, and so on.
