Recently it has been shown that it is possible to measure the two-dimensional distribution of the surface temperature of microscopic specimens. Practical limitations on etalon plate smoothness and parallelism cause the defect finesse to be relatively low, especially in the ultraviolet, and this sets upper limits to the capability of tandem etalon filters to suppress the solar background at tolerable cost to the signal.Ĭombined laser heating and tandem acousto-optical filter for two-dimensional temperature distribution on the surface of the heated microobjectīykov, A. The principal parameter governing the performance of the etalon filters is the etalon defect finesse. Attenuators placed between the etalons can improve the filter performance, at modest cost to the signal transmittance.
The role of reflective coupling between etalons is examined and shown to substantially reduce the contributions of the second and third etalons to the filter performance. Equations for evaluating this parameter are presented for single-, double-, and triple-etalon filter systems. The factor by which the signal to background ratio is enhanced is defined as a measure of the performance of the etalon as a filter. In this research methods for the design and performance analysis of Fabry-Perot etalons as solar background filters are presented.

Morshidi who will be going on retirement leave, handed over his duties to Jaul on Thursday. Morshidi has held the post since AugJaul, an Iban, will be the eighth State Secretary. He takes over from State Secretary Tan Sri Datuk Amar Mohamad Morshidi Abdul Ghani, 63, who will be retiring in August. KUCHING: Deputy State Secretary Datuk Jaul Samion has been appointed as the acting Sarawak State Secretary.
