Zusammenfassung:	Methods and systems for using spectrally separated light pulses to collect more LIDAR information are presented. In one example, a laser pulse may be directed to a point on an object and a corresponding return light signal may be received. The return light signal may be wavelength separated into a plurality of spectral pulse components. Each of the spectral pulse components may be propagated down a separate fiber optic delay line each having a different length to provide a plurality of time-separated spectral pulse components. The time-separated spectral pulse components may be combined to provide a recombined spectral pulse signal. The recombined spectral pulse signal can be provided to an intensity-related measuring/detection circuitry to generate corresponding object location information and object spectral information regarding the point on the object.
