摘要： An objective is to achieve a positional change measurement device which measures positional change of a dynamic measured surface by using speckle patterns while easily reducing influence of fluctuations in a measurement environment temperature. Provided is a positional change measurement device including: a light source; an illuminating optical system configured to guide light from the light source to a measured surface; an imaging optical system; an image pickup device configured to acquire a speckle pattern by receiving reflection light from the measured surface via the imaging optical system; and detected-length compensation means for compensating for fluctuations in a detected length caused by temperature fluctuations. Positional change of the measured surface is measured based on a result of cross-correlation computation performed on multiple speckle patterns acquired at predetermined time intervals.

摘要： A light scanning apparatus is provided that has plural light sources which scan plural light beams in a main scanning direction. The light scanning apparatus comprises a light source control unit that controls the plural light sources. Where an array of N (N≧2) light sources aligned in a sub scanning direction and capable of scanning different positions in the sub scanning direction is called a virtual light source array, and where L (L≧2) virtual light source arrays aligned in the sub scanning direction are formed, the light source control unit causes M ((N−1)≧M≧1) light sources out of the N light sources of each of the L virtual light source arrays to emit light to form a pixel and thereby to form a total of L pixels aligned in the sub scanning direction by giving the same data to the M light sources of each of the L virtual light source arrays.

摘要： A pixel clock generating apparatus comprises a data offset circuit and a pixel generator. The data offset circuit defines multiple data blocks, each data block consisting of a predetermined number of successive clocks, and produces phase data for each data block. The phase data represents an amount and a direction of phase shift to be carried out for a certain clock in each data block. The pixel generator receives the phase data from the data offset circuit and generates a phase-shifted pixel clock a predetermined number of times in each data block based on the phase data.
