Deconvolution is a mathematical operation used in signal processing to recover a signal (e.g. an image) that is degraded by a physical process than can be described with a convolution.
For example, in optical devices (microscopes or telescopes) deconvolution attempts to reconstruct an object from an image that is degraded by blurring and noise. In these cases the blurring is largely due to optical or atmospheric aberrations; the noise is usually photon noise or electronic noise manifesting in low intensity acquisitions. All images are subject to some sort of degrading process. Consider as a 2D example a moving camera that creates a vague picture (the measured image) of a scene (the object). Here the camera displacement is an a priori known degrading process. Restoration by deconvolution applies the inverse process on the degraded image in order to recover the true object. In microscopy the same technique is applied on 2D or even 3D images where the degrading process is the diffraction and aberration of the microscope lens.

Info about single way overlap in multicompent analysis?
Single-way overlap in multicomponent analysis refers to the situation where two or more components in a mixture are partially or fully overlapping in their signal responses, making it challenging to accurately quantify these components individually. This overlap can lead to inaccuracies in the quantification of each component, requiring advanced analytical techniques such as deconvolution or spectral resolution methods to separate the overlapping signals and quantify each component accurately. The extent of overlap and the complexity of the signals will determine the appropriate approach to address this issue in multicomponent analysis.
Seismic data processing?
Seismic data processing involves the analysis and manipulation of data collected from seismographs to create images of subsurface structures. It includes steps like filtering, deconvolution, stacking, and migration to enhance the quality and resolution of seismic images. This processed data is used to interpret geologic features and identify potential hydrocarbon reservoirs in the Earth's subsurface.
Why are pictures from a hubble space telescope clearer and brighter?
Because the Hubble Space Telescope was designed for periodic servicing, the items to be replaced are easily accessible. Ranging in size from a shoebox to a telephone booth, most of these items can be removed or installed using special wrenches and power tools.
