ABSTRACT:
A miniaturized diffractive imaging spectrometer (DIS) has a footprint less than 2×1 mm2, is about 2.5 mm tall (excluding an image detector, which in some embodiments may be a CCD matrix), and covers the entire visible spectral range from 400 nm to 700 nm with resolution of approximately from 2 nm to 4 nm across the field. The DIS is able to function with multiple input waveguide channels, and is flexible in its various possible configurations, as it can be designed to achieve better resolution or higher number of channels or wider spectral range or smaller size.
