Study report on the in orbit calibration of the EUSO telescope

The purpose of carrying out in-orbit calibration of the EUSO instrument requires a careful design of the optical setup to measure the performance of lenses and detectors during the EUSO lifetime. Several requirements drive the design, such as weight, power consumption and payload structure, as well as the need of decoupling the optical performance of the lenses from the responsivity of the foca...

Advanced CCD imaging spectrometer (ACIS) instrument on the Chandra X-ray Observatory

The ACIS instrument has been operating for three years in orbit, producing high quality scientific data on a wide variety of X-ray emitting astronomical objects. Except for a brief period at the very beginning of the mission when the CCDs were exposed to the radiation environment of the Outer van Allen Belts which resulted in substantial radiation damage to the front illuminated CCDs, the instr...

Refractive Index of ZnSe at Cryogenic Temperatures†

This report describes an extensive data set on the refractive index of ZnSe that provides full high resolution coverage of the CRIRES operating range in both wavelength and temperature. By combining our prototype instrument model of CRIRES with these data our project to provide wavelength calibration for IR Echelle spectrographs (WIRE) has reached an important milestone and is ready to support ...

Virtual Musical Instruments

The virtual musical instrument is an interface that allows users to simulate a musical instrument by printing a template on a sheet of paper, placing it in view of the webcam of their laptop, and running the console application. The user then ’plays’ the virtual instrument as if it were a real one, and appropriate music is generated. This is achieved by calibration of the template, detecting th...
