Abstract

The invention discloses a view field diaphragm installation adjustment structure of a one-dimensional imaging heterodyne spectrometer and a view filed detection method. The installation adjustment structure consists of a cylindrical mirror assembly, a work wave band optical filter, a spectrum dimension view field diaphragm, a collimating lens, an interferometer assembly, an imaging lens and a spatial dimension view field diaphragm; and the devices related to the installation adjustment structure and the view field detection method include a star tester, a supervision wave band filter sheet, a collimator, a movable reticle and a gauss ocular lens. The invention adopts the installation and adjustment of the spectrum dimension view field diaphragm under the supervision wave band and the view field detection, and obtains the size of the spectrum dimension through cropping the positioning of the spectrum dimension view field in the optical axis under the isolation ring thickness working wave band and correcting the formula. The invention utilizes the imaging characteristics of one-dimension imaging space outer difference spectrometer, enables the spectrometer to image at different positions of the spatial dimension view field diaphragm through changing the positions of the star points of the real image face of the collimator and calculates the size of the spatial dimension view field through the theory.

Description

technical field [0001] The invention relates to the field of field of view optical systems, in particular to a field diaphragm installation structure and a field of view detection method of a one-dimensional imaging heterodyne spectrometer. Background technique [0002] Spatial heterodyne spectroscopy has been widely concerned and applied in astronomical observations, especially the quantitative detection of trace gases. Spatial heterodyne spectroscopy is mainly used in the quantitative detection of trace gases such as methane, carbon dioxide, oxygen, and water vapor in the atmosphere. [0003] In recent years, the traditional non-imaging spatial heterodyne spectroscopy technology has been developed into one-dimensional imaging, two-dimensional imaging and other forms of spatial heterodyne spectroscopy, in order to obtain high spectral resolution and higher spatial resolution at the same time. Compared with two-dimensional imaging spatial heterodyne spectroscopy, whose spec...
