Title: Controller for optical modulator
Inventor: OOI HIROMI
IPC: H04B10/556
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To efficiently control pre-chirping amount in the direction compensating waveform deterioration due to a transmission system while respectively controlling drift compensation of a modulator by maintaining characteristics excepting the pre-chirping amount of a transmission optical signal equal before/ after the pre-chirping amount is revised. SOLUTION: When the pre-chirping amount is revised, only optical modulators 11 , 12 related to giving of pre-chirping are controlled, and the pre-chirping amount is revised, and this controller is constituted so that the relevant optical modulators 11 , 12 are suppressed, and also, that the characteristics excepting the pre-chirping amount of the transmission optical signal are maintained equal before/after the pre-chirping amount is revised. Then, operation point shifts are interlocked with each other in the optical modulators 11 , 12 arranged in parallel, and the pre-chirping is performed efficiently when plural optical signals with the same light wavelength λ0 are light time division multiplexed. Thus, the pre-chirping amount is revised interlockingly and efficiently.

Title: Image reader
Inventor: KURITA MITSURU
IPC: H04N1/04
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent color slurrings caused in reading of an image in a subscanning direction due to the difference in the afterglow characteristic of each color when the luminous quantity of a white light source for emitting a light to an original is controlled by reducing the centroidal movement of read positions of each color in the subscanning direction caused, depending on the afterglow characteristic of the white light source. SOLUTION: This image reader is provided with a centroidal movement reducing means that reduces the centroidal movement of read positions of each color in the subscanning direction generated, depending on the afterglow characteristic of a white light source. The centroidal movement reducing means controls the light emission quantity based on data that are sampled for plural number of times. In this case, the centroidal movement reducing means conducts control so that the temporal center of a light control section coincides with the center of Hsync by a control signal. Thus, the afterglow amount is shared to a front side and a rear side in a light emission region and then averaged to make the centroidal movement due to the afterglow characteristic very small.  A circuit 18 of the reader delays the output of a circuit 16 for an arbitrary time, based on a setting value from a CPU 17 (so that the light emitting region comes to the center of the Hsync).
