IR sensor for a scanned staggered element linear array having improved cold shielding |
摘要 |
The invention relates to a cold shielding arrangement for use with either an individual staggered element linear IR array or a staggered arrangement of a plurality of such arrays. The cold shielding arrangement consists of a slitted plate spaced from the arrays, each slit being arranged to restrict the field of view of the pixels in both columns of one array in the scanning direction, and a pair of interdigitated pixel level cold shields set on the surface of each array to restrict the field of view of the pixels in the resolution direction.
