A laser irradiation apparatus includes a laser source configured to emit a laser beam to an object that is being conveyed to allow the object to be irradiated with the laser beam; a rotation detector configured to detect rotation of the object to obtain information on the rotation of the object; and circuitry configured to control laser irradiation onto the object based on the information on the rotation of the object.

Laser irradiation apparatus and laser irradiation method

A display device includes a light source unit, a light deflector configured to deflect light from the light source unit, an optical element array configured to be two-dimensionally scanned in a main-scanning direction and in a sub-scanning direction with light via the light deflector, the optical element array having a plurality of optical elements, and a light projecting unit configured to project light received via the optical element array. In the display device, each of a beam spot diameter in the sub-scanning direction on the optical element array and an arrangement pitch of the optical elements in the sub-scanning direction on the optical element array is equal to or greater than a scanning line pitch on the optical element array.

Display device, object apparatus, image forming unit and display method

A HUD device comprising a display device for scanning with light emitted by a light source (e.g., an LD) an optical element array (e.g., a micro lens array) including multiple optical elements (e.g., micro lenses) to form an image and for projecting the light that has formed the image. The display device includes a control unitthat is capable of changing output power of the light In this case, it is possible to provide a display device that is capable of adjusting luminance of an image while controlling against luminance unevenness of the image from occurring.

Laser scanning display with luminance adjustment

An image display device includes a light source to emit light, an image forming element to form an image with the light emitted from the light source, a micro-lens array to be irradiated with the light forming the image, the micro-lens array including a plurality of lens columns arranged in a second direction, each lens column including micro-lenses being arranged in a first direction, the first direction and the second direction being perpendicular with each other, and a projection optical system to project light passing through the micro-lens array toward a transmitting and reflecting member.
