DMPTS IR FPA Detector Multi Parameters Testing System

The DMPTS is an integrated test station, provides the ultra-low noise driving electronics and high quality radiometric stimuli, perform accurate evaluation and testing for IR focal plane arrays detector.

The DMPTS is designed with data acquisition systems, provide powerful, menu driven and flexible GUI software to perform tests and analysis, provide exhaustive and accurate measurement results.

The DMPTS achieves a high degree of versatility, easy to operating. Parameters user defined by GUI software, automatically generate test reports with data and charts.

The DMPTS can interface with the user’s own detector support electronics to perform detector testing and analysis.

Functions

• Noise tests:
• Fixed pattern noise
• Temporal noise
• NETD
• Responsively
• Dynamic range
• Linearity
• Non-uniformity correction
• Bad pixel localization

The DMPTS bench consists of:

• An electronic unit equipped with a set of ultra-low noise electronics.
• A low temperature uniform and highly stabilized IR reference source for noise measurements, NUC and bad pixel tests.
• An optical bench to place the translation stages, blackbodies and detector, also the function to adjust these device location to accurate and calibrated optical signals.
• Two low-noise DC power supply modules for detector and circuit.

The DMPTS  software has the following features:

• User-friendly interface for parameter setting, control operation, pixel remapping.
• Parameters user defined by GUI software, apply these parameters and signals to detector, such as:
• Bias voltage,
• Frame rate,
• Integration time,
• Region of interest,
• Temperature of blackbody,
• A/D parameter definition.
• Setting of parameters for testing functions, simulation test, test item threshold, such as:
• Temperatures for noise measurement and NUC,
• Criteria for bad pixel localization.
• Automatic control of the blackbody depending on the selected functions and the corresponding settings.
• Acquisition and processing of the detector’s video signal, including the exclusive noise and responsively optimization.
• Display and recording of the complete tests results.
• Automatically generate test reports with data and charts.
