Claim One:
1. A multi-spectral camera comprising: a light blocking element having at least one hole configured to allow light from an object being imaged to pass through the light blocking element, the at least one hole having a maximum dimension wherein an angle or direction of light rays from a same spatial point of the object being imaged do not vary more than 1° across the at least one hole; a dispersive element for spreading light from the at least one hole in different wavelength dependent directions; a lens for focusing light from the dispersive element on an image plane; a microlens array for receiving light from the lens; an image sensor for receiving light from the microlens array, wherein the microlens array is located at the image plane or located in a plane between the image plane and the image sensor, further wherein the microlens array and the image sensor are arranged in different planes such that light passing through the at least one hole is distributed across a plurality of pixels of the image sensor, still further wherein an F-number of microlenses of the microlens array does not match an F-number of the lens, but matches a desired spectral range that provides a unique light path for each pixel of the image sensor, without overlap, the image sensor further for generating a pixel value signal comprising incident light values for pixels of the image sensor; and a processor for generating a multi-spectral image from the pixel value signal.
