    Abstract: A compact field spectrograph is described that provides a resolution of 500 or more with no entrance aperture, providing for substantial gain in light throughput, ideal for viewing multiple distant objects with or without telescopic aid, and providing the ability to observe and distinguish a multiplex of objects simultaneously, even if in motion, with minimal or no mechanical tracking required. Spectra may be viewed directly with the unaided eye, or photographed with common consumer cameras.

    Abstract: Provided is a Fourier transform spectroscopy method that removes restrictions on spectral resolution and spectral accuracy in Fourier transform spectroscopy for observing a cyclic repeating phenomenon, that realizes, theoretically, infinitesimal spectral resolution accuracy. After accurately and sufficiently stabilizing the repetition period of a phenomenon, a temporal waveform is acquired by making a repetition period and a time width for observing the temporal waveform of a phenomenon strictly conform, and by performing a Fourier transform, acquired is a discrete separation spectrum in which the inverse number of the observation time window size T is made a frequency data gap. Measurement is repeated while causing the repetition period to change, and the gap of the discrete separation spectrum is supplemented. Thereby, in a case of an observation target in which the existence time of a phenomenon is longer than the repetition period, the spectral resolution of the obtained discrete separation spectrum becomes infinitesimal.

    Abstract: A slitless spectrograph simultaneously records spectra of transient or moving light sources along with spectral references marks positioned alongside the spectra for calibration of unknown spectral lines. The reference marks are provided by groups of optical components which cause undispersed light from the unknown source to be focused on a film above or below the spectrum. The angles at which the light beams creating the references marks strike the grating of the spectrograph are specifically selected such that the rate of movement of the reference marks caused by a change in the incident angle of light from the light source into the spectrograph is related to the rate of change of the position of dispersed light which falls at the position of the reference mark when the spectrograph is precisely aimed at the light source.
