Hybrid linear array detector

Spectrometers Based on Hybrid Linear Array Detectors... 

Mapping experiments in which the sample is moved in both x andy dimensions should not be properly called imaging, since the spectra have not been acquired by an array detector. However, the spectra that are obtained can be treated in exactly the same way as if these spectra had been acquired with an array detector. Commercially available hybrid mapping/imaging instruments have also been described in which a linear array of, say, 32 detectors is used to acquire a line map after which the sample is moved and the process is repeated.

Dhe detector array is a bulk 10X64 pixel Si As hybrid device manufac- d by Hu es Aircraft Co. The detector is assembled from a wafer of tnide-doped silicon material bump-bonded with a matrix of indium con- s to a Hughes CRC-310 direct readout (DRO) integrated circuit mul-exer dup.The array operates as 10 linear rows of detectors in parallel, ii 10 readout chains. The pixel size is 100X100 /aa with a separation of /xm center to center,and the operating temperature of the array is 10-12 The optical system of the camera consisting of two convex ZnSe lenses, ndes a pixel field of view onto the array of 1.23 /pix.
