Quiroga Mellado, Juan Antonio ; Vargas, Javier ; González Fernández, Luis M. ; Belenguer Dávila, Tomás | Optical Society of America | 2010-06-01We demonstrate a method to calibrate a Shack-Hartmann sensor as an orthographic camera. This calibration method permits us to obtain the distance, the rotation matrix between the microlens array and CCD imaging planes, and the projection matrix,[...]texto impreso
González Fernández, Luis M. ; Pastor Sempere, Carmen ; Belenguer Dávila, Tomás ; Arrazola, David ; Fernández, Marianela ; González, Concha | 2016Space optics is present in almost all instruments embarked in spatial missions. Among others large-aperture long-focal length optical systems, spectrometers and visible/IR cameras are common instruments. Operation in the hostile spatial environm[...]texto impreso
Pastor Sempere, Carmen ; Jellema, Willem ; Zuluaga Ramírez, Pablo ; Arrazola, David ; Fernández Rodríguez, M. ; Belenguer Dávila, Tomás ; González Fernández, Luis M. ; Audley, Michael D. ; Evers, Jaap ; Eggens, Martin ; Torres Redondo, Josefina ; Najarro, Francisco ; Roelfsema, Peter | SPIE | 2016SpicA FAR infrared Instrument, SAFARI, is one of the instruments planned for the SPICA mission. The SPICA mission is the next great leap forward in space-based far-infrared astronomy and will study the evolution of galaxies, stars and planetary [...]texto impreso
Quiroga Mellado, Juan Antonio ; Vargas, Javier ; González Fernández, Luis M. ; Belenguer Dávila, Tomás | The Optical Society Of America | 2010-05-01In the optical quality measuring process of an optical system, including diamond-turning components, the use of a laser light source can produce an undesirable speckle effect in a Shack-Hartmann (SH) CCD sensor. This speckle noise can deteriorat[...]texto impreso
Pastor Sempere, Carmen ; Zuluaga, Pablo ; Jellerma, Willem ; González Fernández, Luis M. ; Belenguer Dávila, Tomás ; Torres Redondo, Josefina ; Kooijman, Peter Paul ; Najarro, Francisco ; Eggens, Martin ; Roelfsema, Peter ; Nakagawa, Takao | The Society of Photo-Optical Instrumentation Engineers (SPIE) | 2014-08This paper describes the optical design of the far infrared imaging spectrometer for the JAXA's SPICA mission. The SAFARI instrument, is a cryogenic imaging Fourier transform spectrometer (iFTS), designed to perform backgroundlimited spectroscop[...]
