| Abstract: | In this paper, a representation of transfer function is presentecl for scanning mechanism which exists nonlinear scanning rate. Taking an objective oscillating mirror for example, the paper discuusses the transfer function of the scanning mechanism when scanning angle rate shows high-frequency periodic variation, Low-frequency periodic varication and random motion. The relationships between the tranfser function and the scanning angle departure, scanning rate nonlinearity are also discussed. The results are very significant to guide the disign of scanning mechanism for spaceborne multispectral scanner. |
