1 Introduction

1.1 Atlas

The Atlas 2D analysis system is the ultimate 2D imaging CCD combined

with a spectrometer. The Atlas combines two fundamentally different

devices in one solution giving it unprecedented capabilities and flexibility.

Due to the software the operation of the Atlas is very user-friendly.

The Atlas consists of a 2D RGB imaging CCD and a spectrometer

(spectral range between 380-780nm) with the following camera choices:

2D CCD choices

2MP RGB CCD

8MP RGB CCD

16MP RGB CCD

Spectrometer choices

Spectral engine (380nm-780nm)

Spectral engine (380nm-780nm) + luminance photodiode (flicker)

This Atlas has been developed for two markets:

1) Display market

2) LED panel market

1.2 Atlas highlights

Luminance & colour uniformity measurements

Mura measurements

White point adjustment

Self-calibrating 2D part due to the spectrometer

High accuracy due to spectrometer

2D and spectrometer Auto-range measure function

Dark current compensated

Programmable regions of interest

2 Interfaces

2.2 Power connections

Atlas has a single power supply. Always make sure to use the one

supplied by Admesy. Others are not guaranteed to work and may even

damage the Atlas.

4 Atlas communication

4.1 Atlas generic engine

The Atlas should be connected by the Ethernet port and the USB port. In

order to control the Atlas the following items are required:

1) GIGE driver –for communication with the 2D CCD imager

2) VISA driver –for communication with the spectrometer

3) Generic engine software –this is the control software which

operates the Atlas and does all the calculations. It can be

accessed by SCPI commands through Ethernet.

4) GUI –the graphical interface communicates through TCP/IP with

the engine. You can install our standard GUI or you can make you

own GUI.

The engine software is the heart of the Atlas, it takes care of everything. It

controls the Atlas, it takes care of the calculation necessary for 2D

analysis (mura, uniformity…etc).

The GUI sends a command to Generic engine as for example

CAPture:image. The Engine will on its turn send back the image to the

GUI. The Atlas engine needs to be installed on a pc.

4.2 GUI

The graphical user interface can be made by your own software (examples

are available) or you can use our standard GUI. The graphical user

interface sends commands trough TCP/IP to the Atlas engine which on its

turn takes care.

4.3 Atlas controlled locally

The graphical user interface sends commands trough TCP/IP to the Atlas

engine which on its turn takes care of the received command and sends

back data to the GUI if applicable. Both software packages are on the

same PC. This means the TCP/IP communication is locally and can be

seen as a virtual connection.

4.4 Atlas controlled remotely

The graphical user interface sends commands trough TCP/IP from a

different PC to the Atlas engine which on its turn takes care of the received

command and sends back data to the GUI if applicable. Each software

packages is on a different PC. This means there is a physical connection

between over TCP/IP which enables you to control the Atlas remotely.

5 Device drivers

5.1 Atlas engine

In order to run the Atlas both the GigE driver and the NI-VISA are

necessary. Atlas is only supported under 64 bit systems.

NI-VISA

GigE

Windows 7 (64 bit)

Windows 8 (64 bit)

Not tested¹

Windows 10 (64 bit)

Not tested¹

1 Not tested: expectation is that this will be soon available

We are still working on other platforms, this table will be updated on a

regular basis.

6 Command set structure

6.1 Commands

The functions of the Atlas can be best described via the following

categories.

System commands

Project settings commands

Configuration commands

Measurement commands

Calibration commands

The Atlas engine uses SCPI like commands for control and measurement.

These are ASCII based commands and follow specific rules regarding

syntax. Although the Atlas uses SCPI like commands, they deviate slightly

from the SCPI standard in some cases.

All data communication with the Atlas software can be done with TCP_IP

and is ASCII based. Every command should be followed by a CRLF (\r\n).

Data send back will also be send with a CRLF.

6.2 Command structure

Every command starts with a colon “ : ”, which identifies the root of the

command tree. Each further keyword is also separated a colon. In case

parameters need to be specified, the last keyword and parameters are

separated by a single space character. In case more than one parameter

needs to be specified, the parameters need to be separated by a comma.

The command tables show commands in long and short format. The short

format is specified by upper case characters. It is allowed to use long and

short format or a mixed format. Optional keywords are shown between

brackets [...]. Commands are not case sensitive, so it is allowed to use

both or a mix of upper and lower case. The command structure is valid for

all communication interfaces of the Atlas. It is necessary to terminate a

command by a newline character “\r\n”.

6.3 Data communication

Every command starts with a colon “ : ”, which identifies the root of the

command tree. Each further keyword is also separated by a colon. In case

parameters need to be specified, the first parameters is separated by a

single space character, following parameters are separated by a comma

“,”. There are three possible combinations of write and read:

Only write

Write and read for non 2D data commands (most commands)

Write and read for 2D data commands

The result can be send back as two formats:

ASCII string with CRLF as termination character

In case of 2D data, a flattened string in single float format with no

termination character

In most cases the result will be send back as an ASCII string. However in

the case of 2D data the result is different because of speed

considerations. Transferring such an amount of data in ASCII format would

case a large latency in communication.

When only case 1 is used the first package usually is data which is not of

importance. However in order to support also 2D image transfer we have

implemented this method, whereby the first read indicated the length of the

result.

Send ASCII command terminated with CRLF.

First read is the result and data is in ASCII, terminated

with CRLF.

Send ASCII command terminated with CRLF.

First read is 4 bytes long and is the length of the result in

I32 format. No termination character is used.

Second read, this is the 2D data result. This is a flattened

string (float format). Data is not terminated.
