Abstract:
1. An apparatus for scanning at least one hyper-spectral image, comprising: an optical system for focusing an optical image of a target in a focal plane thereof, wherein the focal plane contains a plurality of row portions of the optical image; a hyper-spectrometer disposed apart from the optical system; and a relay module for selectively relaying one of the row portions of the optical image to the hyper-spectrometer without moving the hyper-spectrometer, wherein the relay module comprises: a relay lens; and a micro-motion device for moving the relay lens, wherein the micro-motion device comprises: a slide rail connected with the relay lens, wherein the longitudinal direction of the slide rail parallels the row portions of the optical image; a stepper motor for shifting the relay lens along the slide rail; and a calculating module for controlling the stepper motor.
