IB’s LES Technology vs Traditional Prism Based Sensors
Light Emitting Sensor (LES) technology is changing the biometric identity landscape.
Based on the science of electroluminescence, LES devices generate fingerprint
images by energizing particles of dielectric phosphor suspended in a thin film substrate. The resulting images are captured using proven digital photography optics.
Integrated Biometrics (IB), a US-based company, and its subsidiaries have been
perfecting the development of LES technology in fingerprint sensors for nearly
20 years. They are the first and only provider of FBI-certified optical fingerprint
sensors based on LES technology. The sensor design, used in dozens of biometric
manufacturers products around the world, offer Appendix F and PIV certified
images in extremely low power consuming, lightweight, rugged devices and
qualify as an optical sensor as required by most project specifications.
How does LES technology work?
LES technology uses energy to excite phosphorus particles suspended across a
thin film substrate. These electroluminescent particles glow via the conductive
properties of a human finger to produce an image of the fingers ridges and valleys.

It takes only a small amount of energy,
transferred using the conductive
properties of a human finger across
the sensor’s bezel and platen, to excite
the phosphor particles in the film. The
result is an image so detailed that even
the body’s sweat pores are evident within
the fingertip’s ridges and valleys.
Capture Optics
Images produced by LES film are
captured via high speed digital
camera optics. Depending on the
imaging sensor type, either a
CMOS camera and traditional glass
lens or a thin film transistor (TFT)
camera are used. Both options
capture high quality images of
the acquired fingerprint(s).
The resulting image file is then transferred using a USB interface to the host PC,
tablet, or smartphone. In addition, this USB connection also acts as the sensor’s
power source. Separate power supplies are not required. The low power requirements of LES technology make these scanners ideal for smartphone and tablet
applications, as these devices can operate for hours without auxiliary power.

Why is LES technology better than traditional prism-based scanners?
While LES technology is optical, it does differ in positive ways from traditional technologies that employ a clear glass platen and prism. Traditional optical sensors only “see”
the surface topography of the finger (or fake finger) presented on the glass. This technology is susceptible to image spoofing. LES sensors inherently guard against spoofing
as they require the friction ridge of the finger to contact the film while simultaneously
contacting the device’s bezel. The connection between LES film and bezel complete
a circuit and create the fingerprint image. Without the conductivity properties of the
human finger, fake fingers will not work. Additionally, the oils, latent prints, and dirt that
are often left behind and ruin images on a traditional glass platen, are simply not “visible” when using the LES sensor. This simple difference between LES and prism-based
sensors means no more cleaning the platen after every single use – LES technology
excels in unattended applications.
