ABSTRACT:
A scanning arrangement for an infra-red imaging device in which a column of I.R. detectors, and similarly a column of L.E.D.'s, scans a field broadside to produce a band of parallel line scans, a number of such band scans being provided to cover the field. Each band scan is performed by a respective mirror facet of a rotating polygonal drum, the facets being tilted at slightly different angles to provide the band displacement. Non-uniformity of the column of I.R. detectors or the L.E.D.'s or the interconnecting channels tends to produce the same pattern of non-uniformity within each band. This is overcome according to the invention by periodically tilting the drum by a random fraction of a band-width so that on successive occasions a particular element of the field is processed by different detector/L.E.D. channels.
