FIELD: physics.
SUBSTANCE: multispectral camera comprises a diaphragm, a dispersing element, a lens, a microlens array, a photodetector and a processor. Radiation enters the multispectral camera through the diaphragm, which has at least one opening, and is directed by the dispersing element in different, wavelength-dependent directions. The lens focuses the radiation from the dispersing element on an image plane. The microlens array receives radiation from the lens and directs the radiation to the photodetector. The processor forms a multispectral image based on values of signals from the photosensitive elements of the photodetector.
EFFECT: forming multispectral images without using scanning systems and removable filters, improved time resolution and simple design of the device.
