Detector configurations for observations of gravity modes in solar radiance.
Abstract
The VIRGO (Variability of Irradiance and Gravity Oscillations) investigation has been selected to fly on the SOHO mission. One of the components of VIRGO is a small imaging instrument with limited spatial resolution. Calculations have been carried out in an attempt to find an optimal geometrical detector configuration for the observation of low degree g-modes in the solar luminosity. The constraints are given as a wish of having the largest possible sensitivity and redundancy with the smallest number of detectors. In addition the crosstalk for different modes at same frequency should be minimized.
