Abstract
A spectral imaging device () includes an image sensor (), a tunable light source (), an optical assembly (), and a control system (). The optical assembly () includes a first refractive element (A) and a second refractive element (B) that are spaced apart from one another by a first separation distance. The refractive elements (A) (B) have an element optical thickness and a Fourier space component of the optical frequency dependent transmittance function. Further, the element optical thickness of each refractive element (A) (B) and the first separation distance are set such that the Fourier space components of the optical frequency dependent transmittance function of each refractive element (A) (B) fall outside a Fourier space measurement passband.
