Paper Abstract

The work was devoted to optimization of time integrated acoustooptical correlators (TIAOC) parameters. To increase time bandwidth product acoustooptical properties of nontraditional cuts for lithium niobate have been investigated. The cut for SAW velocity direction has the most wideband diffraction efficiency. During the work influence of laser diode aperture function, optical path losses, units position accuracy on TIAOC dynamic range has been investigated. Special software gave the opportunity to calculate value of each factor in total TIAOC dynamic range. Computer simulation results of the TIAOC showed the laser diode aperture function in total TIAOC dynamic range. Computer simulation results of the TIAOC showed the laser diode aperture function non-uniformity and optical path losses decreased TIAOC dynamic range up to 12 dB. Optical elements position accuracy for the TIAOC experimental sample was analyzed with the special simulation computer program. The program simulates the device correlator function. The CCD position exactness is about 2.5 mm.
