Title: Light wavemeter and light wavelength regulator
Inventor: LECKEL EDGAR
IPC: G01J9/02
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To measure the signal wavelength of a light source inexpensively and accurately and regulate the wavelength automatically by measuring the optical power of a light beam emitted from an optical component and comparing the measured optical power with a correction data of a light wavemeter thereby regulating the wavelength of the light source. SOLUTION: A light beam from a light source is split through a beam splitter 7 and about 5% thereof is delivered to a beam splitter 6 where it is further split and one split beam is delivered to a photodiode 5 while about 50% of the other split beam is delivered to a birefrigent delay plate 1. The delay plate 1 delays a polarized light in parallel with the low speed axis by π/4 behind a polarized light in parallel with the high speed axis before it is delivered to a polarizing beam splitter 2 and split into two light beams corresponding to the polarization of the delay plate 1. Intensity of the light beam is converted through photodiodes 3, 4 into a current and delivered from a connector 10 through an electric circuit 9 to a data processor, along with the output from the diode 5, in order to calculate the wavelength of the light source.  The calculated wavelength is compared with a previously regulated wavelength of the light source and the signal wavelength of the light source is regulated based on the difference.

Filed: 1993-05-11
Abstract: PURPOSE:To optimize the discretized lattice while inhibiting the generation of a redundant discretized lattice point by giving a practical means simultaneously evaluating the error information and directional properties of current density and simply evaluating an error regarding current density. CONSTITUTION:A cell displays a rectangle in two dimensions and a rectangular parallelopiped in three dimensions to a partial differential equation. Discretization error indices at every axial direction regarding current density are determined from the difference of current density along sides in a pair of mutually parallel sides vertical in the aimed direction and different by positions regarding the axes to the cells in a semiconductor region. The evaluation of the discretization error and estimation of the direction for making the lattice compact are conducted simultaneously. For example, the partial differential equation is solved numerically in the processing of the evaluation of the error of current density, and each current density is obtained (a step 1). Objects to be processed are limited in the cells in the semiconductor region (steps 2, 3, 5, 6). Error indices in each axial direction are acquired (a step 4). Accordingly, the error can be optimized.
