LD3500 Series Low-Cost Digital Linescan Camera
512, 1024 and 2048 Pixels,
and Parallel LVDS Outputs
Features
electronic design enables the
LD3500-series to deliver consistent,
reliable performance while the
sturdy metal housing provides
maximum protection in a variety of
harsh environment and factory floor
conditions.
Description
• 20 and 40 MHz output rate models
• Geometrically precise 14 µm square
pixel linear CCD
• Small size: 2.5" H x 2.5" W x 3.2" L
• High dynamic range (250:1)
• CameraLink and Parallel LVDS
video output models
• 8-bit grey scale resolution
• Antiblooming control
• Single power supply operation
• Electronic exposure control
• Adjustable gain levels
In the LD3500-series digital linescan
camera, PerkinElmer has combined the
best features of photodiode array
detection, high-speed charge-coupled
scanning, and digital line scan camera
technology to offer an uncompromising
solution to the increasing demands of
advanced imaging applications.
The LD3500-series linescan cameras
transform light imaged during a
scene into a digital video signal.
Antiblooming structures within the
sensor ensure superior performance
over a wide range of lighting
conditions. User-defined control is
possible for line rate, integration
time and video data rate.
The LD3500-series are high perform-
ance, low-cost, digital linescan cameras.
The LD3500 features a CameraLink™ or
Parallel LVDS (RS-644) style video
output with resolutions of 512, 1024 or
2048 pixels, which can achieve data
rates of up to 20 or 40 MHz with excep-
tional noise immunity. The cameras are
designed for volume applications where
small size and low cost are required.
• CE mark certified
• Line scan rates to 68 kHz
The LD3500 cameras may be
interfaced to most frame grabber
cards, allowing for a tested, plug and
play solution. Typical high
performance line scan applications
include lumber processing, non-
contact measurement, document
scanning, dimensional gauging,
biomedical imaging, bar code
scanning and many other industrial
and scientific applications.
In order to allow the user to compensate
for variations in illumination found in
"real-world" application environments,
the cameras feature adjustable gain
levels. The LD3500-series cameras
feature a geometrically precise photo-
diode CCD image sensor with 14µm
photo-elements. State of the art

Operating Modes
The LD3500 series cameras can operate
in Master or Slave Mode. When the
camera is set to Master Mode, the camera
operates at its maximum line scan and
data rate. When the camera is set to
Slave Mode, the cameras scan and data
rates are determined by the users input
signals to the camera. The opertaing
mode is set via the serial connection on
the CameraLink models, and is auto-
detected on the LVDS models. Auto-
detection is accomplished by looking for
either a Line Transfer (LT) and/or
External Clock signal. If the camera
receives a LT signal, but no external
clock, it will continue to run a the
maximum data rate, but will only intiate
a LT upon signal. If the camera recieves
an external clock signal, it will run at
that clock signal with either an internal
or external LT signal.

The rising edge of the LT signal
transfers the charge from each
photosite to the readout registers.
The readout registers, in turn,
Should a data rate slower than that
default rate be necessary, an
externally supplied master clock can
be used. The data rate may be run
from 2 MHz to cameras maximum
clock rate. The Line Transfer input
signal transfers the charge from each
photosite to the readout registers.
The readout registers, in turn,
transport the charge from each
photosite in succession to the video
outputs.
transport the charge from each
photosite in succession to the video
outputs. The exposure time of the
camera can be externally controlled
using the LR input. The LR input is
active low (ON) in polarity and
therefore, when not in use, must be
held high or left unattended (OFF).
In this condition, the exposure time is
defined by the period of the LT signal.
Input/Output Signal
Specifications
The exposure time of a LD3500-series
camera can be controlled by using the
external LR input. The LR input is
active low (ON) in polarity and
therefore, when not in use, must be
held high or left unattended (OFF).
In this condition, the exposure time
is defined by the period of the LT
signal. When using the LR input
signal, the exposure period is defined
to be the time between the rising edge
of LT to the rising edge of LR.
Output signals are compliant with
CameraLink specifications.
The LD3500 camera requires a single
DC supply (+12 to 24V) for operation.
An internal oscillator sets the default
data output rate to default model rate
(20 or 40 MHz).
Parallel LVDS (RS-644) Models:
Parallel LVDS models of the LD3500
provide Master Clock (MCLK), Line
Transfer (LT) and Line Reset (LR)
input signals. The MCLK input
determines the data rate frequency for
values up to maximum clock of the
camera. The MCLK input is optional,
as the camera is preset to run off of
the internal oscillator at the default
maximum data rate.
CameraLink Models:
CameraLink allows for 4
manufacturer-defined camera control
signals (CC1-CC4). CC1 is a Line
Transfer (LT) signal. CC2 is a Line
Reset (LR) signal. CC3 and CC4 are
reserved for future assignment.
The LD3500-series camera provides
two output synchronization signals:

The Camera Clock (CCLK) operates at
either the MCLK frequency or default
camera frequency, and is synchronized to
the analog video. The output of the CCLK
signal can be used to capture digital video
data by a frame grabber or digitizer.

pixel and goes low one CCLK period before
the last valid pixel.

In all modes of operation on the LVDS

to the necessity of storing all video data
into memory before the video is output.

The LD3500-series camera features an
adjustable video gain. This allows users
to amplify the video signals for individual
application needs. Photo Response Non-

connector. Gain can be set from 0 to
24.5 dB in increments of 3.5 dB. Gain
settings are not lost when the camera is
powered down.

Gain levels are set by differential RS-644
gain control inputs on the camera
connector. The gain levels can be set at 1,
2, 4 and 8X full-scale gain, allowing the
user to easily configure the camera output
to suit their application needs. Gain
settings are not held after power down;
proper input signals must be given at
start-up, and held throughout operation
for gain settings to remain at desired
levels.
