Abstract

An apparatus for receiving data through the atmosphere at rates greater than 1 gigabit/sec. is provided (Figure 1). The apparatus includes a holographic unit (reference numeral 116 in Figure 1) and a detector assembly (reference numeral 106 in Figure 1). The holographic unit receives light having different wavelengths representative of data at different frequencies. The holographic unit focuses the light on the detector assembly, preferably, a plurality of pick-off mirrors spaced from each other (reference numeral 120 in Figure 1). Each pick-off mirror collects light at a predetermined wavelength. Each pick-off mirror directs the light at its associated wavelength to a very fast, high refractive index focusing lens (reference numeral 124 in Figure 1). The detector assembly also includes a plurality of detector units (reference numeral 128 in Figure 1). Each detector unit is in contact with one of the lenses. The detector units are able to receive tightly focused light having the transmitted data for subsequent processing.
