Deconvolution, also known as inverse filtering, is the process of extracting the impulse response from known input and output signals. This technique is vital in scenarios where the system's characteristics are unknown, and they must be inferred from the observable signals. Deconvolution involves several mathematical techniques to derive the impulse response. One common approach is polynomial division. In this method, the input and output sequences are treated as coefficients of...

SEC-BioSAXS measurements of biological macromolecules are a standard approach for determining solution structure of macromolecules and their complexes. Here, we analyze SEC-BioSAXS data from two types of commonly encountered SEC traces—chromatograms with fully resolved and partially resolved peaks. We demonstrate the analysis and deconvolution using scatter and BioXTAS RAW.

Photoacoustic ophthalmology (PAOM), an optical-absorption-based imaging modality, provides the complementary evaluation of the retina to the currently available ophthalmic imaging technologies. We report the using of PAOM integrated with spectral-domain optical coherence tomography (SD-OCT) for simultaneous multimodal retinal imaging in rats.
FAQs
The measured spectrum is represented as a combination of component spectra, then mathematical fitting estimates how much each component contributes. Reference data can provide expected component patterns, while constraints help restrict the possible solutions. This approach is useful when the original signals cannot be resolved directly and the measured spectrum contains contributions from several substances.
Reference data give the analysis spectral patterns against which the measured signal can be compared. Constraints provide additional limits for separating contributions within the mixture, helping the fitting process distinguish plausible component estimates. Together, these elements support more specific identification and concentration estimates than interpretation based only on the visibly overlapping measured spectrum.
Identifying component contributions is only part of the analysis; estimating their concentrations indicates how strongly each component contributes to the measured sample. These estimates can strengthen biomarker analysis, process monitoring, and interpretation of complex biological measurements. In bioengineering, that quantitative perspective helps connect spectral patterns with the composition of tissues, cells, biomaterials, or molecular mixtures.
A typical workflow begins with a measured spectrum from a complex sample. The analysis then represents that spectrum using component spectra and applies mathematical fitting, reference data, or constraints to separate the contributions. The resulting estimates can be used to identify components and assess their concentrations, supporting interpretation of signals that remain combined in the original measurement.
The approach can support measurements obtained with fluorescence, Raman, and infrared spectroscopy. These techniques may generate complex signals from biological tissues, cells, biomaterials, or molecular mixtures, where multiple component contributions overlap. Applying deconvolution to such data can improve component identification and concentration estimates for downstream bioimaging, biomarker analysis, or biological measurement interpretation.
Researchers may use it when measurements from tissues, cells, biomaterials, or molecular mixtures contain overlapping contributions that are difficult to interpret directly. In those settings, the method helps separate estimated component signals and supports applications such as bioimaging, biomarker analysis, and process monitoring. Its value comes from making complex biological spectra more informative.
The analysis can provide estimates of individual component contributions and their concentrations within a complex measured spectrum. Those outputs may improve identification of substances in biological samples and clarify the meaning of fluorescence, Raman, or infrared measurements. As a result, researchers can strengthen bioimaging, biomarker analysis, process monitoring, and interpretation of complex biological data.
