Precautions
Read the Manual
Please read the manual carefully before using the camera for the first time.
Do Not Drop
Camera
The camera is a sensitive optical device, handle with care at all times. Do not drop the camera
and avoid mechanical shock to the camera.
Keep Foreign
Matters Outside
the Camera
Do not spill liquids on the camera. The camera is not liquid or waterproof.
Do not drop metallic objects into the camera. This might cause a short-circuit and damage the
camera.
Cleaning
Keep the shade cap on the camera head when it is not in use to avoid contaminating the
prism.
It is recommended that the camera be serviced by Atmel if the front surface of the prism is
very dirty because the surface area of the prism cannot be fully accessed from the front.
If there are small amounts of contaminants or dust on the prism surface, use a clean lint free
cotton swab or other non abrasive medium dipped in acetone or pure alcohol to clean the
prism surface. Shake excess solvent off before touching the surface of the prism to avoid
streaking. Atmel is not responsible for any scratches or damage inflicted by the customer to
the front surface of the prism.
To clean the exterior casing of the camera, use a soft, dry cloth. In case of severe stains use a
small amount of pure alcohol or isopropyl alcohol. Do not use acetone or other volatile sol-
vents such as benzene or thinners.
Do Not Open the
Camera
Do not open camera. The warranty of the camera expires immediately upon opening. Only
authorized service personnel may open the camera.
Ventilation
Allow sufficient air circulation around the camera. If this condition is not met, the camera might
shut down during operation because it is designed to do so in order to prevent damage to the
optical assemblies since a further temperature increase may damage the camera.
Storage
Do not store the camera in temperatures over +55
C. There is a permanent temperature indi-
cator inside the camera, which is installed to ensure that if the camera is damaged due to over
temperature, the warranty of the camera may be void.
Electromagnetic
Fields
Do not operate the camera in the vicinity of strong electromagnetic fields (above the require-
ments of CE conformity). This may cause erroneous operation of the camera.
Transporting
Transport the camera in its original packaging. If the original packaging has been discarded,
package the camera with care in a thick layer of soft, preferably anti-static material when
transporting. Do not use material that allows the camera to fall to the bottom of the package
while transporting. Do not transport with optics attached.

Camera
Overview
Color Separation
The incoming light is separated to three (Red, Green and Blue) color images by an RGB beam
splitter (Figure 1). The spectral distribution of each color is standardized and well known. By
attaching a CCD to each of these color outputs, it is possible to measure the intensity of each
color image.
Figure 1. RGB Color Separation Beam Splitter
The CCDs are aligned to each other to get the perfect image of the three measured color com-
ponents. All three CCDs see exactly the same area of the object at the same time.
Corresponding pixels of all three sensors are very precisely positioned optically in the same
place (Figure 2). This makes the color analysis simpler and does not require any line matching
or synchronizing. The resolution of the camera is the same as for the individual CCD array.

Camera Operation
The CCDs convert the incoming light to electrical charges. The amount of charge generated in
each of the individual pixels is directly proportional to the intensity of light they receive. The
resulting charge packets are transferred into two high-speed CCD shift registers and trans-
ferred to the output charge-to-voltage converters of the CCDs. The output video generated is
Correlate Double Sampled (CDS) and the result is amplified by the user accessible gain factor
prior to digitization to 10-bit.
Figure 3. Camera Synoptic
The AKYLA cameras operate in a mono-shot mode. For each rising edge of the NewLine sig-
nal the camera responds by sending out the digital data stream of the previous exposure time.
The output frequency is constant. The distance in time between two NewLine edges can be
set to any value above the specified minimum. The reciprocal of this time is the line rate (Hz).
Other programmable functions include:
Color channel specific programmable exposure control
Color channel specific programmable analog gain
Color channel specific programmable digital gain
Programmable offset
Retrieval of the PROM version number
Non-volatile memory banks for programmable settings
