A slide on which an observation object by a microscope is placed, is provided. A first mark indicating a reference line along a first direction and a second mark indicating a specific position on an extension of the reference line along the first direction are separately arranged in a vacant area between a label area used to arrange a label and a cover glass area used to arrange the observation object and a cover glass. A position reference is provided by the specific position on the extension of the reference line along the first direction.

Sample handling, processing and analysis methods and apparatus are described. According to one aspect, a sample processing method includes providing a sample, providing a reference frame which comprises a plurality of markers arranged in a predefined pattern, wherein individual ones of the markers are uniquely identifiable from others of the markers, and associating the reference frame comprising the markers with the sample. The markers are amenable to human or machine reading and for computational manipulation in some examples.

A display panel bonding device and a correction apparatus and method thereof. The correction apparatus includes: a fixture assembly including a first fixture and a second fixture coordinating with each other. The first fixture is provided with a first alignment mark, the second fixture is provided with a second alignment mark, and alignment between the first fixture and the second fixture is achieved via the first alignment mark and the second alignment mark; and an image acquisition assembly configured to acquire a first image of the first alignment mark of the first fixture and a second image of the second alignment mark of the second fixture respectively. The first image and the second image are used for acquiring an alignment parameter of the first alignment mark and the second alignment mark to correct alignment between the first fixture and the second fixture.

Methods and apparatuses related to fiducial designs for fiducial markers on glass substrates, or other transparent or translucent substrates, are disclosed. Example fiducial designs can facilitate visual recognition by enhancing edge detection in visual perception. In example fiducial designs, optical features on glass substrates can re-direct light so as to present a bright image region. Such optical features can include surface relief patterns formed in a coating on the surface of glass substrates. An exemplary method for manufacturing the fiducial markers can involve transfers of a fiducial design across a master mold or plate, a submaster mold or plate, and a target glass substrate. A fiducial marker can facilitate the use of the substrate in a variety of applications, including machine vision systems that facilitate automated performance of manufacturing processes on input working material.

A kinematically engaged yoke system (KEYS) for multiple-order-diffraction engineered material may comprise a harness comprising a frame and a plurality of semi-kinematic keys disposed on the frame, wherein the semi-kinematic keys are configured based on a MOD-side mechanical profile of a plurality of segments of a multiple-order-diffraction engineered material, and wherein the MOD-side mechanical profile, when engaged with the semi-kinematic keys, functions as a fiducial that provides alignment between neighboring segments; and one or more shims disposed between one or more pairs of neighboring segments of the plurality of segments of the multiple-order-diffraction engineered material, wherein the one or more shims facilitate alignment of the one or more pairs of neighboring segments of the plurality of segments based on a translation across one or more surfaces of the one or more shims.

A scale includes a substrate, a metal layer of Ni formed on one principal surface of the substrate, and a scale grating formed on the metal layer. A plurality of gratings of Cr are disposed at a predetermined interval in the scale grating.

A reference position setting method according to the present disclosure is a reference position setting method for setting a reference position for recognizing whether or not an operation unit displayed as a virtual image has been operated. The reference position setting method includes: a step of displaying a marker displayed as a virtual image larger than an object approaching the marker; a step of detecting the object approaching the marker; and a step of making a color or shade of the outer edge of the marker different from a color or shade of the center of the marker after the step of detecting the object.
