Camera Control Software for Time-Resolved Spectroscopy

Overview

Software for measurements that capture short-lived light in nanosecond slices and separate it by wavelength
Built for the person operating the instrument at the bench
One window for the whole run - connect, set conditions, capture, review, save and export
Capture settings and spectroscopy settings stored in the same file as the frames, so any saved run says what produced it

Vendor software handled capture only - settings written down separately and matched to result files by hand
Runs that step through several delay settings meant re-entering and re-saving at every step
Judging whether a frame was usable required opening it in another tool, so not at the bench
Converting pixel positions to wavelength repeated by hand for every run
A setting past the camera's internal memory meant failure partway through a capture

Exposure and delay timing, trigger mode, capture region, binning, gain voltage and gating set in one panel and applied together
Capture modes chosen by purpose - fixed conditions, table-driven repeats, live preview
Results shown immediately as a 2D frame and as a wavelength spectrum, either separately or both at once
Instrument state (connected, recording, reading out) and three temperature points shown continuously at the top
Warning and error signals from the instrument translated into readable lines in the log
Captures saved with their settings as a single file, with several files loadable at once for comparison

Connect camera → set conditions → capture → review on screen → save file → export in the needed format
Table-driven runs apply each row in order and advance on their own

Frames and spectra written as picture files or as numeric files
Full capture settings written as a separate table file, ready to quote in a report

Exposure and delay pairs listed in a table, with a set number of frames captured automatically per pair
Table saved and reloaded as a file, so the same conditions repeat in a later session
Each pair recorded with its frames, so the delay behind any result stays identifiable

Requested frame count checked against the camera's internal memory before capture begins
On overflow, the available and requested counts are shown and the run stops - no failure partway through

Frames darker than a set threshold across every pixel are treated as signal-free and not stored
Skipped count shown as capture runs, keeping only usable frames when signal arrives rarely

Capture one frame → transfer and display it → move to the next
A saturated frame raises a warning and stops the run, protecting the gain stage from excess light

Known reference lines paired with pixel positions, fitted with a polynomial from 1st to 4th order
Fit quality shown as a coefficient of determination, so the calibration can be judged on the spot
The resulting conversion stored with the capture, so reopening it gives the same wavelength axis

A section of the spectrum fitted with one of three line shapes, giving centre position and width
Background separated with its own polynomial from 1st to 4th order
Analysis available on averaged frames, reducing noise where signal is weak

Spectroscopy settings and the time table saved automatically and restored at the next launch
Settings held in the camera backed up before reset and restored afterwards, so reconnecting does not lose them

Capture, review, analysis and export in one program - no switching tools mid-measurement
No more writing down settings and matching them to results by hand
Any saved file states the conditions behind it, making past runs reproducible and comparable
Repeat measurements across delays defined once in a table and run unattended
Capture failures from bad settings blocked by a check before the run starts
Capture conditions once copied into a lab notebook now exported as a table file for reports

From software development to equipment integration and engineering, we can work out the approach that fits what your project needs.
