description Method for viewing a laser spot included in a multispectral image representing an optical field composed of pixels including a plurality of components, the laser spot being produced by a laser pointer and having a wavelength taking values in a range of wavelengths dependent on operating temperatures of the laser pointer. The method includes: obtaining a multispectral image in which each component corresponds to the same instant of acquisition and represents a spectral band in a plurality of spectral bands covering continuously a spectral domain comprising said range of wavelengths; applying a contrast-accentuation procedure to a subpart of the multispectral image comprising the laser spot in order to obtain a subpart in which a contrast between the laser spot and a background is improved; and generating an image allowing display of the laser spot using information obtained following the application of said procedure.
