BACKGROUND [0001] This present application is a continuation-in-part of U.S. patent application Ser. No. 10/324,314, filed Dec. 19, 2002, by R. A. Wood, and entitled "MULTI-BAND SENSOR". [0002] The invention may pertain to sensors and in particular to sensors for detecting the presence of fluids and other substances. More particularly, the invention may pertain to sensors that have detector sensitivities of several bandwidths. "Fluid" is a generic term that includes liquids and gases as species. For instance, air, water, oil, gas and agents may be fluids. [0003] The related art might detect at several wavelengths; however, the results of detection may not be sufficiently accurate because of sensor structure or other impediments resulting in different fields of view for detection at different wavelengths. SUMMARY [0004] The invention may be a multi-band sensor for detecting various fluids having emissions with various wavelengths and intensities. BRIEF DESCRIPTION OF THE DRAWING [0005] FIGS. 1a, 1b and 1c show upward and downward fields of view for a sensor; [0006] FIG. 2 shows the sensor relative to a gas cloud and the sky. [0007] FIG. 3 illustrates a thermoelectric detector; [0008] FIGS. 4a and 4b reveal the sensor in conjunction with a vacuum package; [0009] FIG. 5 is a layout of the detectors and filters of the sensor; [0010] FIG. 6 is a graph showing transmission peaks of two thin-film interference filters; [0011] FIG. 7 is a layout of detectors and their connections into groups; [0012] FIG. 8 is a side view of several detectors and their corresponding filters; [0013] FIG. 9 is a schematic of some electronics for the sensor; [0014] FIGS. 10a, 10b and 10c show absorptivity coefficients of an agent and two interferents; [0015] FIG. 11 shows the effect of variation of an angle of incidence on a narrow-band filter; [0016] FIG. 12 reveals a light integrating sphere; [0017] FIG. 13 is a table of dimensions for a sensor; [0018] FIG. 14 is a diagram of a multi-band gas sensor; [0019] FIG. 15 is a graph of an interference pattern of light that impinges a linear detector array; and [0020] FIG. 16 is a graph of a spectrum of a detected gas or gases.
