5.3 LDS 6, Optics Housing CD 6
The LDS 6, Optics Housing CD 6 (shown in the figure below) is designed for in situ
measurements. It consists of a transmitter and a receiver creating a single path measurement
situation. The beam diameter is expanded to about 25 mm in order to improve performance in
high dust load (>1 g/m

The transmitter includes a lens and a connection for the optical fiber located in the focal plane
of the lens. The receiver contains a lens and the sensor electronics. The sensor electronics
consist of the detector module and the sensor card. The powering of the sensor electronics is
performed with a twisted pair copper cable delivering 24 VDC. The detector card is a detector
with pre-amplifier and the sensor card consists of driver electronics for the optical return signal
and DC/DC-converter.
The laser light is coupled from the optical fiber in the transmitter to its lens and passes through
a wedge tube (for protection of the lens) and then through the measurement volume. The lens
in the receiver (also protected with a wedge module) focuses the incoming laser light on the
detector where it is converted to an electrical signal. This signal is amplified and converted to an
