Title:
MULTIBAND COMMON-OPTICAL-PATH SPECTRUM COMBINED REMOTE SENSING MEASUREMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2015/101062
Kind Code:
A1
Abstract:
A multiband common-optical-path spectrum combined remote sensing measurement system and method. The system comprises an infrared window (1), a two-dimensional rotating mirror (2), a planar mirror (3), a reflective multiband infrared lens (4), a Fourier interference spectrum module (5), a spectrum combined-processing module (6), a power supply module (7), a refrigerating module (8), and a display module (9). Incident light enters from the infrared window (1), is reflected by the two-dimensional rotating mirror (2), and then is reflected by the planar mirror (3) to the reflective multiband infrared lens (4) and then is split by a spectroscope (42). The transmitted light is focused by means of a convergent lens and is imaged on an infrared detector (43). The reflected light is focused on an infrared optical fiber coupler (44) and enters the Fourier interference spectrum module (5) through an infrared optical fiber, so as to form an interferogram, and further, spectrum data is obtained by means of a Fourier transform. The spectrum combined-processing module (6) effectively combines wide-spectrum imaging and non-imaging spectrum data, and controls the two-dimensional rotating mirror (2) to point to a target, thereby implementing intelligent remote sensing measurement. The multiband common-optical-path spectrum combined remote sensing measurement system has capabilities of measuring a spectrum of a local scene region and performing multi-target tracking spectrum measurement, and has high speed and a proper data amount, and needs low cost.
