Provided is a detection system for a luminaire fixture including a sensor and a laser meter to allow positioning of a sensor for precise positioning toward a viewing area. The sensor includes a sensor mount to attach the detection system to an existing luminaire, a sensor lens to perceive a viewing area, and a sensor housing to protect the sensor lens. The laser meter includes a laser to project a focused light path for positioning, and a laser housing to protect the laser. The sensor lens is positioned with respect to the laser, causing the sensor lens to move with respect to the laser. Also provided is a method for configuring an adjustable detection system for a luminaire.

According to an embodiment, an inspection apparatus includes an irradiation mechanism, an imaging device, a movable mechanism, and a control processor. The irradiation mechanism irradiates an inspection target with light. The imaging device captures an image of the inspection target through a lens. The movable mechanism changes, with respect to an axis extending in an inspection direction for the inspection target, an angle between the lens and a horizontal plane or an angle between the imaging device and the horizontal plane such that a sample surface of the inspection target, a principal face of the lens, and an imaging face of the imaging device conform to the Scheimpflug principle. The control processor adjusts sensitivities in an image of the sample surface captured by the imaging device at different levels in the image depending on a position in a perpendicular direction to the inspection direction.

Inspection apparatus and inspection method

A print apparatus is disclosed. In some examples, the print apparatus comprises a print head to deposit print agent onto a substrate; a detector to detect a fiducial; a first light source to back-illuminate the substrate, such that light from the first light source is to be detected by the detector through the substrate; and processing apparatus. The processing apparatus is to operate the print head to deposit print agent to form a first fiducial on a first side of the substrate, the first fiducial comprising a shape of a first colour and having a first dimension, and a background of print agent of a second, different colour, wherein the first dimension of the shape does not exceed a corresponding dimension of the background; operate the print head to deposit print agent to form a second fiducial on a second, opposite side of the substrate, the second fiducial comprising an inverted version of the shape of the first colour; operate the first light source to back-illuminate the substrate; operate the detector to detect the first and second fiducials; and determine whether the first fiducial is aligned with the second fiducial. A method and a machine-readable medium are also disclosed.

Determining alignment using fiducials

The present disclosure relates to a measure system, which includes a photographic device and a processing unit. The photographic device is configured to capture a first plane at a first angle and capture a second plane image at a second angle. The processing unit is electrically coupled to the photographic device and configured to calculate a first spacing between a target object and a reference object based on the first plane image. The processing unit is also configured to calculate a second spacing between the target object and a reference object based on the second plane image. According to the first spacing, the second spacing and an ideal position which is stored in the processing unit, the processing unit can accurately calculate an error spacing between the target object and the ideal position.

Measure system and method thereof

The disclosed apparatus, systems, and methods provide for a displacement sensor with a multi-position image sensor. The displacement sensor includes an optical lens. The displacement sensor includes an image sensor configured to view an object through the lens along a plane of focus that is not parallel to an image plane of the image sensor. The displacement sensor includes a laser for illuminating the object by the displacement sensor, wherein the laser is: spaced from the lens at a fixed distance, and configured to project a line of light along the plane of focus of the image sensor. The displacement sensor comprises a first configuration wherein the image sensor is at a first location along an image plane with a first field of view along the plane of focus, and a second configuration at a second location with a different field of view.
