- A new method for actively tuning FBG’s to particular infrared wavelengths for oh emission lines suppression R. Benítez-Álvarez F. Martínez-Piñón V. G. Orlov Física, Astronomía y Matemáticas general methods infrared numerical photometers This paper presents the conceptual design for a new method for the suppression of OH emission lines at near-infrared (NIR) wavelengths by actively adjusting the aperiodic fiber optic Bragg gratings tension. First, we prepared an experimental study in which we simulated an OH emission line using a semiconductor laser at 1548.43 nm and a commercial FBG, with a Bragg wavelength of 1547.76 nm. We demonstrated that the grating Bragg wavelength can be adjusted by controlling the linear deformation of the fiber with a force in the range of 0 to 53.88 gf (0.528 N) that provides a sensitivity of 0.014 nm g −1. Second, we proposed the design of a system connected to the telescope instrumentation, with the different stages that would allow monitoring the suppression of emission lines. 2019 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171631019 https://www.redalyc.org/journal/571/57171631019/ https://www.redalyc.org/journal/571/57171631019/html/ https://www.redalyc.org/journal/571/57171631019/57171631019.epub https://www.redalyc.org/journal/571/57171631019/movil 10.22201/ia.01851101p.2019.55.02.19 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.55
