HPD – TA | High-Performance Digital Temporal Analyzer Overview The HPD-TA Temporal Analyzer software is a high-performance control & imaging software, designed specifically for controlling streak systems and performing streak measurements in a wide variety of application fields. It provides precise data acquisition and pre-processing of two-dimensional streak data, including a full range of data correction and calibration possibilities. It integrates the various hardware devices belonging to a complete streak measurement setup into a single coherent system by controlling all system components...

Data acquisition Live imaging Live Mode allows viewing the streak image on the PC monitor in real-time. It is mainly used for monitoring the light signal during jobs such as optical alignment, focusing, laser adjustment, and so on. The example picture shows the time-resolved spectrum of a pulsed laser diode in real-time. Event synchronization In case of single-sweep streak setups the image grabbing must typically be synchronized with the streak camera and external events. HPD-TA supports versatile trigger schemes facilitating this task, including handshake signaling with the streak camera in...

HPD – TA | High-Performance Digital Temporal Analyzer Image display Dim image of a plasma discharge (by courtesy of Kyushu University) Frequently, images are very faint due to very low signal levels, which makes them difficult to inspect visually. The look-up-table (LUT) tool provides easy control over the image appearance by adjusting brightness, contrast and pseudo-colors, without affecting any measurement data. By this means even the dimmest phenomena can be visualized clearly and brightly. Image zoom & scroll allow inspecting tiny details when desired. All these features work in real-time...

Data correction HPD-TA offers a full range of data correction and pre-processing functions. These are used to eliminate data artifacts caused by the characteristics of the experimental setup and measuring apparatus. Background correction Background correction is a subtractive correction eliminating offset signal caused by camera dark current or any other unwanted background signal such as stray light. Time-resolved fluorescence spectrum After background subtraction After shading correction Oscillating laser diode After curvature correction Oscillating LD, integration with large jitter After jitter...

HPD – TA | High-Performance Digital Temporal Analyzer Data calibration Major data formats: 2-D data (images): format (HPD-TA default format, IMG up to 32 bits/pixel) IFF format (mainly for presentation, T publishing, printing) SCII format (for easy import into data A analysis software, spreadsheets, etc.) different image sequence formats Two (IMG file collection; HIS container) 1-D data (profiles): SCII format, 2-columns (for easy A import into data analysis software, spreadsheets, etc.) All data formats are fully documented in the extensive user manual. HPD-TA automatically attaches calibration...

Application-specific modules (optional) Some application-specific add-on modules for the HPD-TA software are available as options. They are seamlessly integrated into the HPD-TA and can be used without leaving the main program. TA-Fit: Module for fluorescence lifetime data fitting This is a tool for quantitative analysis of the intensity profiles from fluorescence decay emissions. Features Fitting engine with adaptive least-square fitting algorithm Optional deconvolution with excitation pulse Determination of multiple lifetime components Quality of fit control via residuals, chi-square, autocorrelation...
