What is Bio, medical, dental & pharmaceutical infrared imaging?

Infrared cameras are used in a variety of bio(medical), dental and pharmaceutical applications. Here we will give an overview of some applications and list the necessary key features of infrared cameras that are used for these applications.

 

 

Bio(medical) infrared imaging

The best-known application is probably fever detection in (air)ports. To reduce the spread of infectious diseases or viruses, thermal LWIR cameras measure the skin (face) temperature of every passenger. To contain the spread of the disease, people with an elevated skin temperature need to go through further medical examination.
The cameras that are used for fever detection are thermal LWIR cameras, with temperature calibrations in order to determine the skin (face) temperature of a human person as accurate as possible. Often a black body reference source is used to improve accuracy of the measurement. Our Gobi thermal camera offers the thermal stability and temperature measurement accuracy that is needed for this application.

Another interesting biomedical application is SWIR fluorescence imaging for deep tissue in-vivo imaging. This technique is used in cancer research and offers a resolution of a few milimeters.
After optical excitation, the fluorescence of organic dyes, fluorescent proteins or quantum dots are detectable in the low-loss window for biological tissue (1000 – 1700 nm).
This is exactly where our Xeva-1.7-320 TE3 and Cheetah-640CL TE3 score best. Due to theirThermo-Electric cooling and their high sensitivity in this wavelength range, they are a perfect solution for this application. 

Dental infrared imaging

SWIR cameras in an OCT (optical coherence tomography) setup are used in dental applications. For example, they can be used to identify caries in an early stage by seeing inside teeth and gums (up to a few mm). For dental infrared imaging we offer our Bobcat-640 series, with both GigE and CameraLink interfaces. 

Pharmaceutical infrared imaging

SWIR cameras are commonly used in hyperspectral imaging systems for pharmaceutical applications. For example, similar tablets of generic drug compounds such as aspirin, acetaminophen, vitamin C and vitamin D can be inspected. Based on their spectral signatures in the SWIR band, the presence (or absence), or spectral homogeneity of multiple compounds is detectable. This technique finds application in quality control, or detection of counterfeit medicines.

What features are needed?

  • Extended SWIR wavelength range
    SWIR InGaAs detectors can be extended into the visible (0.4 - 1.7 μm) band; other SWIR detectors operate in the (1 - 2.35 μm) band
  • High image resolution
    The amount of pixels has an important impact on the image. The higher the resolution, the more detail your image contains
  • High frame rate
    High frame rates allow us to capture fast moving objects
  • Easy connectivity
    We offer several different interfaces for an easy integration into your system
  • Advanced image processing for high quality images
    Autogain, automatic exposure control and contrast enhancement result in the best image quality in any condition

Extreme compact size and low weight

Given the extremely compact size and low weight of the Xenics XS-1.7-320 SWIR camera it was extremely easy to integrate it into our existing optical setup.
