2125046 9311444 PCTABScor01 An incident optical signal from a potential enemy threat is captured by an array of apertures (1, 16) which are connected to a number of broadband filters (21-24). The broadband filters (21-24) have overlapping band pass regions to cover the wavelength spectrum of potential threats, but not with the spectral resolution of a larger number of narrowband filters. To further increase resolution without adding additional filters, each broadband filter is connected to an optical delay line (31-34) which converts wavelength into a time delay. To enable measurement of the time delay, additional optical lines (91-94) with no relative delay are connected directly from the apertures (1-16). The time difference between when a signal arrives over optical delay lines (31-34) from the filters and when a signal arrives over optical lines (91-94) directly from the array of apertures (1, 16) is then reconverted to wavelength to a high degree of resolution.
