摘要： A microlens array includes N lenses ranging from a 1st lens to an Nth lens and a lens arrangement area. N is a positive integer. The lens arrangement area has the N lenses arranged in array. The lens arrangement area receives light emitted from a light source. An ith (i being 1st to Nth) lens satisfies a conditional expression below: −20°≤θ≤20° where θ denotes an angle formed by a main-axis orientation of double refraction and a reference orientation.

摘要： An object detecting apparatus includes: a light projection unit that is an array light source in which each of a plurality of light emission areas emits light, an optical scanning unit that performs scanning with the light, which is emitted from the light projection unit, in a first direction, and a light receiving unit that receives reflected light which is the light, with which the scanning is performed, being reflected by an object, and an object information acquiring unit that detects presence/absence of the object based on emission timing at which the light is emitted from the light projection unit and light receiving timing at which the light receiving unit receives the reflected light.

摘要： A light irradiation apparatus includes an irradiation unit including a light source to emit light to a process-target object, a light source driving circuit to drive the light source, a light source controller to control the light source driving circuit to change a light output level of the light source, and a light spot controller to control energy or energy density of a beam spot of the light on the process-target object depending on an operation mode, and a transition mode that one operation mode is being changed to another mode. The light spot controller sets the energy or energy density during the transition mode lower compared to either of the energy or energy density during the one operation mode before the transition mode and the energy or energy density during the another mode after the transition mode.
