Abstract: Method and arrangements for obtaining and associating 2D image data with 3D image data are provided. the image data being based on light triangulation, performed by an imaging system, where a measure object with first light and an image sensor senses reflected first light from a measure object, during a first exposure period resulting in a first image with first intensity peaks occurring at first sensor positions, SP1. The measure object is also illuminated with second light(s) and any reflected second light is sensed from the measure object by the image sensor during third exposure period(s) resulting in one or more third images. For respective first sensor position, SP1, in the first image it is selected a respective third sensor position, SP3, in said one or more third images.

Abstract: Method and arrangements for inspection of a drinking straw (101; 201) involving use of the drinking straw (101; 201) as a light guide for inspection of a sidewall (102; 202) of the drinking straw (101; 201) based on light leakage of guided light out from the drinking straw (101; 201) via the sidewall (102), such a through a damage (204) in the sidewall (102). It is illuminated (601), by means of one or more light sources (123), a first portion (131) of the drinking straw (101; 201) so that at least some of the light (127) on the first portion (131) is transmitted through a sidewall (102; 202) of the drinking straw (101; 201) into the drinking straw (101), and is guided therein. It is provided (602) one or more digital images (241) imaging another, second, portion (133; 233) of the drinking straw (101; 201) during said illumination.

Abstract: System and sensor (10) for imaging characteristics of an object (2). The sensor comprises at least a first area (11) and a second area (12) of pixel elements arranged to absorb electromagnetic radiation from the object (2) and to convert the radiation absorbed into electrical charges. The first area (11) has a first degree of resolution and the second area (12) has a second degree of resolution different from the first degree of resolution and the first area (11) is arranged to image one type of characteristics and the second area (12) is arranged to image another type of characteristics.
