Methods and apparatuses for aligning and diagnosing the laser beam traversing an optical train in a highly space-efficient, lower cost and/or retrofit-friendly manner are disclosed. The optical components of the optical train are mounted such that one or more optical components can direct their exit laser beam to partially or wholly scan across one or more downstream sensors. Correlation data between physical disposition of optical components and the points of impact data and/or beam quality data are employed to, among others, align and/or diagnose the laser beam and/or localize failure sites and/or optimize maintenance schedule.

System, including methods and apparatus, for optical detection. The system may comprise a light source to generate a beam of light, an optical element including a light guide and an exit window, and at least one detector.

The present invention relates to an arrangement and to a method for wavefront analysis comprising a radiation source (8) that emits an electromagnetic wavefront of electromagnetic radiation (1) to be analyzed; a spatially resolving detector unit (4, 4a, 4b, 4c) for detecting the electromagnetic wavefront; and an electronic evaluation unit (5, 7) connected to the detector unit (4, 4a, 4b, 4c). The at least one beam guidance unit (3) for guiding the electromagnetic radiation (1), that is only diffractive and/or reflective, has at least one opening (3a, 3b, 3c) and the detector unit (4, 4a, 4b, 4c) is arranged behind the at least one opening (3a, 3b, 3c) of the beam guidance unit (3) in the direction of propagation of the electromagnetic radiation (1) for detecting a diffraction pattern of the electromagnetic radiation (1) diffracted at the at least one opening (3a, 3b, 3c).

An ambient-light-sensing hole structure package and a method of manufacturing the same are provided. The ambient-light-sensing hole structure package includes a transparent cover, a decorative layer, a porous structure layer, and an optical adhesive. The transparent cover has a surface. The decorative layer is disposed on the surface and the decorative layer has an opening that exposes a portion of the surface. The porous structure layer is disposed on one side of the decorative layer and the porous structure layer covers the portion of the surface. The porous structure layer includes a plurality of through holes, and the through holes overlap with the opening. The optical adhesive is interposed between the decorative layer and the porous structure layer.

System, including methods and apparatus, for optical detection. The system may comprise a light source to generate a beam of light, an optical element, and a detector. The optical element may include a light guide having a shaft and a tip, with the tip forming a beveled end of the light guide. The optical element may extend into the beam, such that the tip and at least a portion of the shaft are located inside the beam, and a window of the optical element is located outside the beam. Light of the beam incident on the tip may be transmitted longitudinally through the light guide and out the window, while light of the beam incident on the shaft may be transmitted transversely through the shaft and remains in the beam downstream. The detector may be configured to detect light received from the window.
