“…the optimization problem (1.1) is reduced to the search for the most intensely emitting frequency interval in the black-body radiation spectrum. This optimization task was solved in [27]. The interval [v1, v1+∆] with a maximal value of the total energy density Ep (v, T) can be found from the following conditions: , ) [28,29], the conditions (2.5) can be presented in the form:…”

“…Chapter 2 proposes a solution for this optimization task. For an ideal filter, this solution is associated with finding the most intensely emitted interval in the spectrum of thermal radiation, solved in our previous publication [27]. Here we use the previously obtained results to select the parameters of an optimized coherent filter.…”

“…This filter provides the best values of the total emitted radiation at a given width of the frequency interval. The parameters of this new filter are selected in accordance with the solution of the optimization task for finding the most intensively emitting interval of the blackbody spectrum of thermal radiation [27]. It is expected that this filter will provide the best coherent properties at a given value for the total intensity of the transmitted light.…”

A new optimized band-pass filter for wavelengths is proposed to increase the optical temporal coherence of thermal light. The choice of parameters for this filter is based on solving an optimization problem for finding the most intensely emitted frequency interval in the black-body radiation spectrum. The calculated frequency interval is also the narrowest band for the coherence filter for a given value of the total transmitted energy. As a result, the interval found can be used to achieve the highest possible coherent properties at a given level of total energy that has passed.The achieved coherence length values for such optimized band-pass filters are calculated.Analytical results are given for finding optimal intervals and calculating the coherence of optimized filters.Keywords: optimized band-pass filter; temporal coherence of thermal light; degree of the temporal coherence, filters for thermal radiation
