Freeform imaging spectrometer design using a point-by-point design method

Applied Optics, 2018
In this paper, we present a novel design method of freeform imaging spectrometers. All the freeform surfaces including the grating surface are generated point-by-point. The rays coming from multiple wavelengths, multiple fields, and different pupil coordinates are all used, and the refraction/reflection as well as the diffraction of the grating are ...

Block designs on 196 points

Archiv der Mathematik, 1989
According to a result of \textit{A. Delandtsheer} and \textit{J. Doyen} [Private Communication], if G is a block-transitive automorphism group of a 2-\((v,k,\lambda)\) design, then G acts primitively on points, unless there exist two integers \(\beta\), \(\gamma\) such that \[ v=\frac{\binom{k}{2}-\beta}{\beta} \times \frac{\binom{k}{2}- \gamma}{\gamma}
