Scientific paper

The results of the Crab pulsar observations with the photometrical MANIA (Multichannel Analysis of Nanosecond Intensity Alterations) comlex at the 6-m telescope are presented. More than 12 millions photons in UBVR-bands simultaneously with time resolution of 10^(-7) s were detected. Using the original software for search for optical pulsar period, we obtained the light curves of the object with time resolution of about 3.3 mu s. Their detailed analysis gives the spectral change during pulse and subpulse, the shape of the pulse peaks, which are plateaus (with the duration of about 50 mu s for the main pulse), limits for an amplitude of fine temporal (stochastic and regular) structure of pulse and subpulse and the interpulse space intensity. The results of CCD-spectroscopy of the Crab pulsar show that its summarized spectrum is flat. There are no lines, neither emission nor absorbtion ones. Upper limit for line intensity or depth is 3.5 % with the confidence probability of 95 %.
