Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth etc. dimension--rather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wavelength, polarization state, or one or more spatial dimensions--or indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these.

I claim: 1. A spatial mapping system for mapping a region; said system comprising: a light source for emitting at least one thin, fan-shaped beam from a moving emission location toward such region, a thin dimension of the beam being oriented generally parallel to a direction of motion of the emission location; an imaging device for receiving light reflected from such region and forming an image of the reflected light; means for separating the reflected light to form plural reflected beam images representing different aspects of such region, respectively; and an image-responsive element for receiving and responding to the plural beam images. 2. The system of claim 1, wherein: the separating means comprise means for discriminating between spatially different aspects of such region. 3. The system of claim 1, wherein: the separating means comprise means for discriminating between aspects of such region that are carried in portions of the beam received at different angles. 4. The system of claim 3, wherein: the discriminating means comprise means for forming discrete plural reflected beam images from portions of the beam received at different angular ranges, respectively. 5. The system of claim 1, wherein: the separating means comprise means for discriminating between aspects of such region that are carried in different polarization states of the beam. 6. The system of claim 1, wherein: the separating means comprise means for discriminating between aspects of such region that are carried in different spectral components of the beam. 7. The system of claim 1, wherein: the separating means comprise means for discriminating between combinations of two or more different aspects of such region that are carried in different characteristics of the beam, at least one of which characteristics is selected from among: spatially different aspects of the beam, different polarization states of the beam, and different spectral components of the beam. 8. The system of claim 7, wherein: at least two of said characteristics are selected from said spatial, polarization and spectral characteristics. 9. The system of claim 1, wherein the emission location is selected from the group consisting of: a spacecraft; an aircraft; another type of vehicle; and another type of moving platform. 10. The system of claim 1, wherein: the emission location is a fixed light source cooperating with a scanning system to provide a moving image of the light source. 11. The system of claim 1, wherein: the light source comprises means for emitting the at least one beam into such medium that is a generally clear fluid above a generally hard surface. 12. The system of claim 1, wherein: the light source comprises means for emitting the at least one beam into such medium that is a turbid medium, including but not limited to ocean water, wastewater, fog, clouds, smoke or other particulate suspensions. 13. The system of claim 1, wherein: the light source comprises means for emitting the at least one beam into such medium that is a diffuse medium, including but not limited to foliage at least partially obscuring a landscape. 14. A spatial mapping system for mapping a region; said system comprising: a light source for emitting a beam whose cross-section has an aspect ratio on the order of 1:1, from a moving emission location toward such region; an imaging device for receiving light reflected from such region and forming an image of the reflected light; means for separating the reflected light to form plural reflected beam images representing different aspects of such region, respectively; and an image-responsive element for receiving and responding to the plural beam images. 15.
