| dc.description | Both a high level of developing the spatially spot-like and one-dimensional input devices and the
flexibility of a design inherent in two-dimensional optical systems with similar modulating
components make it possible to realize various opto-electronic processing systems with an
improved productivity. This is why a one-dimension acousto-optic technique can be successfully
involved into developing an extremely high-bit-rate data processor based on the algorithm of triple
product correlations. Practically, triple product correlations originate within an optical scheme
including the modulated light source, representing the first input port, and two wide-aperture
acousto-optical cells forming two other input ports. Due to specifically constructed lens system,
initially modulated light beam is crossing sequentially the apertures of acousto-optical cells oriented
at right angle to each other. Finally, a CCD-matrix integrates the received optical signal with
respect to time and registers the resulting triple product correlations. In a view of arranging similar
acousto-optical processor for modeling triple product correlations, potential performances of the
progressed design for similar processor are estimated as well.
This triple product acousto-optical processor is oriented to studies in the extra-galactic
astronomy as well as to searching the extra-solar planets, so that algorithm of the space-and-time
integrating is desirable for a wideband spectrum analysis with an improved resolution. It includes
1D-acousto-optic cells as the input devices for a 2D -optical data processing. The importance of this
algorithm is based on exploiting the chirp Z-transform technique providing a 2D-Fourier
transform of the input signals. The system produces the folded spectrum, accumulating advantages
of both space and time integrating. Its frequency bandwidth is practically equal to the bandwidth of
transducers inherent in acousto-optical cells. Then, similar processor is able to provide really high
frequency resolution, which is practically equal to the reciprocal of the CCD-matrix photo-detector
integration time. Here, the current state of designing the triple product acousto-optical processor in
frames of the astrophysical instrumentation is presented. | |
