Abstract
A spectral imaging device (1312) for capturing one or more, two-dimensional, spectral images (1313A) of a sample (1310) including (i) an image sensor (1328), (ii) an illumination source (1314), (iii) a beam path adjuster (1362), and (iv) a control system (1330). The illumination source (1314) that generates an illumination beam (1316) that is directed along an incident sample beam path (1360) at the sample (1310). The beam path adjuster (1362) selectively adjusts the incident sample beam path (1360). The control system (1330) controls (i) the illumination source (1314) to generate the illumination beam during the first capture time, (ii) the image sensor (1328) during the first capture time to capture first information for the first spectral image (1313A), and (iii) the beam path adjuster (1362) to selectively adjust the incident sample beam path (1360) relative to the sample (1310) during the first capture time while the image sensor (1328) is accumulating the information for the first spectral image (1313A).
