Compact type ground object image and spectrum detecting instrument with spectrum electronic speed controller selectable

Abstract

The invention discloses a compact type ground object image and spectrum detecting instrument with a spectrum electronic speed controller selectable. The compact type ground object image and spectrum detecting instrument with the spectrum electronic speed controller selectable comprises a spectral imaging module with different spectrum sections, a spectrum detecting module, a shared data collection circuit, a spectrum control circuit, a main control circuit and software. According to the compact type ground object image and spectrum detecting instrument with the spectrum electronic speed controller selectable, the spectral imaging module and the spectrum detecting module are combined to achieve parallel and integrated detection of an image and the wide spectrum section of a spectrum of a ground object target, a fixed view filed matching relation exists between the spectral imaging module and the spectrum detecting module, the spectrum electronic speed controller is selectable by means of novel optical splitting devices--electrical modulation optical splitters such as an acousto-optic tunable filter and a liquid crystal tunable filter, and due to multi-module control and collection of circuits for integration and reutilization, the compact structure, flexible detection and high efficiency of data are achieved.

Description

Technical field: [0001] The present invention relates to a ground feature map detector, in particular to a compact ground feature map detector with optional electric spectrum adjustment. Detection of remote sensing detection instruments. Background technique: [0002] Morphology and spectrometry are the main methods to study the structure and composition of ground objects, which are based on the spectral characteristics of different ground objects, as well as the different sizes and shapes of particles. The imaging spectrometer can obtain the spectral information of the target pixel with high spectral resolution while obtaining the two-dimensional spatial information of the observed target. It is possible to directly distinguish and identify the target on the spectral image cube. Disaster monitoring, marine, digital city and other national economic aspects and military applications such as camouflage recognition and combat environment reconnaissance have important applicati...

Problems solved by technology

[0005] In summary, due to the high spatial resolution, high spectral resolution, wide spectral range and large field of view of the existing imaging spectrometer, it is not suitable for portable ground object map detection due to the large amount of data, large volume and heavy weight of the instrument. Requirements for volume and weight of instrument and deep space exploration spectrometer
