Abstract
A multi-spectral camera comprises a blocking element () having at least one hole () allowing light to pass through. A dispersive element () spreads light from the at least one hole () in different wavelength dependent directions and a lens () focuses light from the dispersive element () on an image plane (). A microlens array () receives light from the lens () and an image sensor () receives the light from the microlens array () and generates a pixel value signal which comprises incident light values for the pixels of the image sensor (). A processor then generates a multi-spectral image from the pixel value signal. The approach may allow a single instantaneous sensor measurement to provide a multi-spectral image comprising at least one spatial dimension and one spectral dimension. The multi-spectral image may be generated by post-processing of the sensor output and no physical filtering or moving parts are necessary.
