1Product profile
NUCTECH®RT1003E Raman Liquid Explosive Detection System (LEDS) has been
designed and manufactured by Nuctech Company Limited for security inspection applications.
This version has been specifically designed with the requirements of airport security lanes in mind
since a single RT1003E can be located between, and accessed from, two adjacent lanes. In this
application it meets the requirements of the ECAC Type B Liquid Explosive Detection Systems
(LEDs)
The RT1003E uses Raman spectrum technology and identifies the material at the
molecular level. RT1003E can analyse most dangerous materials in most types of container and
identifies the threat material. The inspection process is simple, rapid (a few seconds) and the False
Alarm Rate is very low. These characteristics make the RT100E very efficient in airports for
security inspection of Liquids, Aerosols and Gels (LAGs).
RT1003E employs a two sided door to enclose the laser beam whilst providing easy access
from either side. This means it can be used for between two security inspection channels and
improving efficiency by minimising the distance the Security Staff have to move.
The outer appearance of the RT1003E is shown in Figure 1. Further details are shown in
Figure 2 to Figure 5.

The Raman spectrum of a material has 'unique fingerprint' type properties, and RT1003E
assesses these to identify the material
RT1003E provides nondestructive inspection of the material and does not destroy any of
the material.
With a fast inspection throughput capability the RT1003E can complete the analysis in a
few seconds. The next inspection can be carried out without any recovery interval being
required.
Thanks to its' capability and automatic spectrogram database updating function
RT1003E can inspect and analyze most common dangerous liquids, aerosols and gels and
analyze their composition. It can automatically update the spectrogram database according to
specific requirements of users to expand the inspection scope and enhance the range of
materials it can identify.
RT1003E provides a user-friendly Operator interface that comprises a 7-inch LCD touch
display and software interfaces designed with ergonomic considerations as a key driver. It
can store analysed data and has a wide range of data interface- options to export data and
integrate with other devices.
RT1003E does not use a radioactive or ionising source and is safe for Operators to use.
3Technical principle
3.1 Technical theory of Raman spectroscopy
When a substance is irradiated, some of the scattered photons change their energy. This
phenomenon is called inelastic scattering. It was first discovered by Indian physicist C.V. Raman
in 1928 and was named Raman scattering. The energy change of the inelastic scattering depends
on the molecular energy level of the irradiated substance. Different molecules have different
rotational and vibrational energy levels, therefore, Raman spectrums have fingerprint properties,
and molecules can be identified by analyzing the spectrum of Raman scattering light.
RT1003E has a large spectra library composed of Raman spectrum of dangerous liquids.
When a substance is inspected, it is irradiated by laser light and the Raman spectrum is collected.
Substances are identified by comparing their Raman spectra with those in the library.
The RT1003E's optical part comprises the following primary parts: (A) laser transmitter (B)
external light path and (C) spectrometer.

Figure 6 Optical part
The entire inspection process of RT1003E generally includes excitation, collection, optical
filtering, spectrum splitting, examining and analyzing functions.
Excitation:
The laser transmitter emits laser light, which passes through the filter to remove the
background radiation and is then focused on the substance to be examined.
Collection:
After the substance is irradiated, the incident photons are scattered by the molecules of the
substance. The scattered light includes Rayleigh scattering whose wavelength is the same
with that of the incident light and Raman scattering whose wavelength is different from that
of the incident light. Part of the scattered light is collected by lens and collimated.
Optical Filtering:
The collected and collimated scattered light will pass through a specially coated lens which
filters out the Rayleigh scattering. The Raman scattering will pass through the lens.
Spectrum splitting:
On entering the spectrometer, the filtered Raman scattering light is diffracted by the grating
of the spectrometer into with different wavelengths which are received by different pixels of
the Charge-coupled Device (CCD).
Examining and analyzing:
The CCD can turn optical signals into electronic signals. By analyzing electronic signal
intensity on different pixels, the CCD can obtain the light signal intensity and then obtain the
Raman spectrum of the substance. By comparing the peak position and intensity of the
Raman spectrum collected with those of spectrums in the database, the device can analyze
whether the substance is dangerous and which category it is.
