… FP rings and allow the diameters to be measured accurately, the telescope must be of good
… A limited amount of lateral movement of the eyepiece is required to allow the FP rings to be …

… To begin it is instructive to study a simplified optical system used to project the FP rings which
can be found in most texts on optics, and is reproduced in Fig. 1. The pattern on the screen …

… In the experiment, the grid was a negative plate, obtained by contact, in white light, from
the negative photograph of the FP rings. Both plates used were Agfa Gevaert 10 E 75-type. …

… In such a setup, a grid cannot be employed because the radii of the FP rings are given by ρ
= f λ / e K 0 − K = f 2 / R m K 0 − K , , the radius of the source illuminating the FP is given by r = …

… Quantitative determination of the linewidth was determined from diode array measurements
of the FP rings. Pulse durations and output energies were measured with a photodiode and …

… Having the spatial spectrum located on thin FP rings can also be used to multiplex a number
of sequentially addressable spatial filters in the Fourier plane . Ideally, one would like to …

… The diameter of the FP rings are recorded as a function of temperature and plotted[4] [5]. The
graph shows abrupt changes in the diameter of the FP rings indicating the PTTS and giving …

Illusion is a software package designed to synthesize Fabry-Perot data for the Brazilian Tunable
Imager Filter (BTFI) project which is developing an instrument for the SOAR telescope at …

… all the FP rings will be illuminated. Kastler also proposed that laser action would be possible
in these FP modes. This paper reports observation of intense emission into the FP rings of a …

… FP results were grouped into concentric rings at 1, 3, 6 and 10 from central fixation for
analysis (FP rings 1–4, respectively), and the mean sensitivity of each ring used for analysis. MP …
