The hyperspectral MR Series of spectroradiometers consist of a FTIR Michelson interferometer configured with dual output ports used to cover the LWIR and the MWIR + SWIR spectral range simultaneously.
MR Series FTIR Spectroradiometers
In terms of reliability and performance, the MR Series are the leading field infrared spectroradiometers, with undisputed market dominance since its launch in 1989 (more than 150 systems installed globally). An extreme high spectral resolution and radiometric reproducibility, sensitivity, and wavelength accuracy have helped the MR Series of spectroradiometers earn a positive reputation.
The combination of the high-performance FTIR technology and the high radiometric accuracy has made the MR series the preferred FTIR spectroradiometer. Some of the clients stated that they prefer the ABB MR Series instrument because it has capacity to provide spectral measurement precision to meet their expectations.
Specifically, the high resolution provides narrow spectral structure in the infrared radiation domain that is highly critical to military characterization requirements. The MR spectroradiometers series were used by many defense research organizations in more than 20 countries around the world.
Superior Design
Equipment reliability and confidence in device performance is required for efficient and smooth measurement campaigns or field trials. The MR series spectroradiometers are distinguished from other commercial FTIR spectroradiometers for their durability and robustness.
The rotary scanning mechanism uses corner-cube-retroreflectors and frictionless flex-pivots. The interferometer design has been proven with over 3600 units produced and more than 400 billion scan cycles successfully realized. The permanently aligned interferometer (patented rotary scanning mechanism) demonstrates high reliability as well as exceptional stability of radiometric response.
As the MR interferometer is well balanced with respect to its center of rotation, it can be operated in any orientation, and it is useful for airborne operation.

Capturing Fast Moving Targets
Quickly evolving targets are moving in space and/or feature unsteady radiated intensity. They are a combination of unsteady radiated energy and unstable position in space, which make it difficult to capture the radiated energy with good radiometric accuracy.
Considering a rocket, a missile, a plane, a flare, or explosions as examples, the rapidly evolving targets are traveling in position within the instrument FOV and their spatial size and radiant intensity change over time. Explosions stay at the same place, however, the size and the radiated intensity differ over time.
Rapid Characterization using Simultaneous Bands
Quickly evolving target measurements require very short measurement interval of time and measurement of all the spectral bands at the same time so the relative intensity of all the spectral bands remain in good agreements. Consecutive measurement of the spectral bands (i.e. filter-based spectroradiometer) can result in spectral band relative intensity errors as the radiant intensity of the target alters during the measurement period.
The MR series FTIR spectroradiometer technology is perfect for retaining an excellent relative agreement between the spectral bands, as all of the wavelengths are simultaneously measured through the measurement time.
