Title: Fast projection data computing apparatus
Inventor: NAGAI HIDEO
IPC: G01N23/04
Filed: 1988-11-30
Abstract: PURPOSE:To achieve a higher speed of a projection data generating computation by Fourier transform by reducing any one part or the whole part of the number of data, operand and the like out of the number of control data. CONSTITUTION:An orthogonal coordinates-polar coordinates data converter SRPC utilizes a nature that the results of two-dimensional Fourier transform presents a complex conjugation symmetry concerning an origin in a frequency space xsieta plane to perform a total projection data generation from data at an upper half (eta>=0) or at a lower half (eta<=0) or at a right half (xsi>=0) or at a left half (xsi<=0) in Fig. (a). When a frequency component is known on polar coordinates at omega>=0 (or omega<=0), a component of the remaining omega<0 (or omega>0) can be determined from a required expression. An SIFFT is a Fourier inverted transform device which applies a Fourier inverted transform to an input frequency component omegan>0 (or omegan<=0) in a direction thetam on polar coordinates to generate a projection data in this direction. An output data is stored into a data memory DS4 and this computation is processed at a high speed as discrete Fourier transform.

Abstract: PROBLEM TO BE SOLVED: To cut down the rise time and the fall time of a light emitting element, and to increase the switching speed of the photooutput of the light emitting element. SOLUTION: A signal Vb , which is in the logical condition reverse to a signal Va of the logical condition same as an inputted digital signal, is outputted from an input circuit 2. Reference voltage Vrefa and Vrefb , which level changes to the inverse direction and to the same direction of the logic level of the digital signal based on the Va and Vb , are generated by reference voltage generators 3a and 3b. The changing range of reference voltage of the Vrefb is larger than that of the Vrefa . The magnitude relation between Va and Vb against the Vrefa and the Vrefb is judged by differential comparators 4a and 4b, and comparative judgment signals Vb1 (positive logic) and Vb2 (negative logic) for the two values are outputted. As a result, the Vb2 becomes a lag phase against the Bb1 .  Pulse currents Ia and Ib are grown from the Vb1 and Vb2 , and a driving current Id , which is formed by combining the above-mentioned pulse currents, is allowed to flow to the b2, light emitting diode 1. A peaking part is added to the rising and the falling of the driving current Id based on the above-mentioned phase difference.
