Spectrometer image enhancement

Abstract

This document discloses scientific instrument support systems and related methods, computing devices, and computer-readable media. For example, some embodiments provide a computer-implemented method for obtaining a digital image of a spectrum from a time series of frame data of the spectrum projected onto an image sensor by an optical system of a spectrometer. The method comprises: obtaining the time series of frame data of the respective spectra recorded while the projected spectrum moves relative to the image sensor; transforming the frame data to align the recorded spectra; and combining the transformed frame data to generate the digital image.In some embodiments, the method may further include upsampling each image frame to create a respective upsampled image frame, and transforming the upsampled image frames to align the recorded spectra. The upsampling of each image frame may include computing additional pixels between the sensor pixels by interpolating the pixel array to create an interpolated pixel array.
