An Eye for Detail
Concepts for increasing the geometrical resolution of thermographic cameras have belonged to the state of the art of
technology for years. InfraTec is now taking this one step further. With MicroScan, the company is introducing an
option to quadruple the image format for a radiometric thermography camera used in the civil sector with cooled FPA
photon detector for the first time. For models of the ImageIR® high-end camera series, this means that images can be
recorded with up to (2,560 × 2,048) IR pixels (5.2 Megapixels). Users profit from a greatly improved resolution of fine
structures in the thermogram.
Fast and efficient solution
Behind the function is a newly developed, fast-rotating MicroScan wheel, which is integrated into the camera. It
ensures that four different individual exposures are taken per wheel revolution, which are offset laterally by half a
pixel each. These individual exposures are brought together in real time into a thermogram with quadruple image
format. Each pixel in the image represents a genuine temperature measured value and not an interpolated image
point. In this way, thermography achieves a new quality. Through the spatial oversampling of the MicroScan, images
gain in quality noticeably. For example, creation of aliasing artefacts in the image can be prevented.
All this is done not only precisely, but also at enormous speed. How quickly this happens is shown by the example of
the ImageIR® 8300 hp. If the camera is in full-frame mode with its (640 × 512) IR pixels, the MicroScan wheel turns
much faster than 5,000 revolutions per minute. Thanks to such high speeds, users with MicroScan can
thermographically analyse processes with moving measurement objects or changing temperatures. The technology is
not only predestined for use in micro-thermography, but also for a wide variety of security applications.
New quality in recognition of details
Regardless of whether the measurement has a static or dynamic character – the unusual richness of detail in the
thermogram's image representation is very impressive. The exposures are extremely low in noise and show the
measurement objects with very fine resolution. A look at the edge transitions of the objects shows this especially well.
Angular object edges or curves are also reproduced exactly even when digital zoom expands the image section greatly.
Use of MicroScan simplifies evaluation and analysis of thermograms for the user, as considerably more details can be
recognised on the images.
The InfraTec infrared sensor and measuring technology company was founded in 1991 and has its headquarters
in Dresden, Germany. The privately held company employs more than 200 employees and has its own design,
manufacturing and distribution capabilities.
With its Infrared Measurement business unit, InfraTec is one of the leading suppliers of commercial thermal
imaging technology. In addition to the high-end camera series ImageIR® and the VarioCAM® High Definition
series, InfraTec offers turnkey thermographic automation solutions.
Spectrally single and multi channel infrared detectors, next to infrared sensors with electrically tunable filters
based on MOEMS, count among the products of the infrared sensor division. These detectors can be used in gas
analysis, fire and flame sensor technology and spectroscopy.
