摘要： A range finding apparatus includes a light emission unit including a light source and a light source driver, a light detection unit, and circuitry. The light source driver supplies a plurality of drive pulses having different pulse width at different time periods. The light detection unit receives the light emitted from the light emission unit and then reflected from an object. The circuitry calculates a range to the object based on a time difference between one time point when a pulse light is emitted from the light source and another time point when light reflected from the object is received by the light detection unit. One of the drive pulses set with a smaller pulse width is set with a sine wave pattern, and another one of the drive pulses set with a greater pulse width is set with a rectangular wave pattern.

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 method for measuring a deviation in timing of start of writing in scanning lines is implemented by an optical scanning device that scans a surface to be scanned with light beams from light-emitting elements having first and second light-emitting elements which are arranged so as to be displaced from each other in a direction corresponding to a direction of the scanning lines. The method includes: detecting timing at which light from the first light-emitting element is received by a light receiving element, as a first time, the light receiving element outputting a synchronization detecting signal before start of writing; detecting timing at which light from the second light-emitting element is received by the light receiving element, as a second time; and obtaining the deviation in timing for the second light-emitting element with respect to the first light-emitting element based on a difference between the first and second time.
