1 Introduction

1.1 Atlas

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

with a spectrophotometer. The Atlas combines two fundamentally different

devices in one solution giving it unprecedented capabilities and flexibility.

Because of the software the operation of the Atlas is very user-friendly.

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

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

2D CCD choices

2MP RGB CCD

8MP RGB CCD

16MP RGB CCD

Spectrophotometer choices

Spectral engine (380nm-780nm)

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

This Atlas has been developed for two markets:

Display market

LED panel market

1.2 Atlas highlights

Luminance & colour uniformity measurements

Mura measurements

White point adjustment

Self-calibrating 2D part by integrated spectrophotometer

High accuracy due to spectrophotometer

2D and spectrophotometer auto-range measure function

Dark current compensated

Programmable regions of interest

2 Interfaces

2.1 Communication interfaces

2.2 Power connection

The Atlas is powered by a single power supply. Only use the power supply

provided by Admesy. The use of other power supplies is not supported

and may result to damage to the device.

3 Installation

The installation sequence is represented in the flow below.

4 Atlas communication

4.1 Atlas Core

The Atlas requires both Ethernet port and USB port being connected. In

order to control the Atlas the following items are required:

GIGE driver –for communication with the 2D CCD imager.

VISA driver –for communication with the spectrometer.

Atlas Core –this is the control software which operates the Atlas

and does all the calculations. It can be accessed by SCPI

commands through Ethernet.

Atlas GUI –the graphical interface communicates through TCP/IP

with the Core. Installation of the provided GUI is optional. It is also

possible to develop a GUI based on the measurement needs.

The Atlas Core 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 the Atlas Core as for example

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

GUI. Installation of the Atlas Core on a computer is required to operate the

Atlas.

Atlas Core

4.2 Atlas GUI

Installation of the Atlas GUI provided on the USB stick is optional. It is also

possible to develop a GUI based on measurement needs (examples are

available). The purpose of the GUI is to send commands trough TCP/IP to

the Atlas Core that provides the communication to the device.

4.3 Atlas controlled locally

The Atlas can be controlled locally if both Atlas Core and Atlas GUI are

installed on the same computer. In this case, TCP/IP communication is

locally and can be considered a virtual connection.

4.4 Atlas controlled remotely

For remote control, the Atlas Core and Atlas GUI do not have to be

installed on the same computer. The GUI sends commands through

TCP/IP from one computer to the Atlas Core on another computer. The

computer with Atlas Core executes received commands from the GUI and

sends back data to the GUI. As Atlas Core and GUI are installed on

different computers, a physical connection between two computers is

required for remote control.

5 Device drivers

5.1 Atlas Core

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

necessary. Atlas is only supported by 64 bit systems and can be used only

on operating systems as shown in the table below. Support for other

operating systems is currently in progress.

NI-VISA

GigE

Windows 7 (64 bit)

Windows 8 (64 bit)

Windows 10 (64 bit)

6 Command set structure

6.1 Commands

The functions of the Atlas can be divided into the following categories:

System commands

Project settings commands

Configuration commands

Measurement commands

Calibration commands

The Atlas Core 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, 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 carriage return and line feed character “\r\n”.
