摘要:
A method of generating 3D information of a sample using an optical microscope includes: varying the distance between the sample and an objective lens of the optical microscope at predetermined steps, capturing an image at each predetermined step. In one example, the method further includes: determining a characteristic of each pixel in each captured image; determining, for each captured image, the greatest characteristic across all pixels in the captured image; and comparing the greatest characteristic for each captured image to determine if a surface of the sample is present at each step. In another example, the method further includes: determining a characteristic of each pixel in each captured image; determining, for each captured image, a count of pixels that have a characteristic value within a first range; and determining if a surface of the sample is present at each step based on the count of pixels for each captured image.

An object of the invention is an arrangement for determining four-dimensional properties of an interface (100) of an object, the arrangement comprising a light source (102). The arrangement comprises means (104) for forming photonic jets to be utilized in imaging of the interface (100), means (105a,b) for performing large field of view interferometric imaging of the interface (100) and their (104, 106) combination, means (108) for passing said light being close to the interface (100) and direct the light to the interface, and said means (108) create an image. The arrangement comprises means (106) for performing phase shifting interferometric imaging of the interface (100), imaging means (110) for receiving light from the interface (100) modulated by e.g. microspheres (108) for forming super-resolution image information by combining light interferometry with the photonic jets, and a processor unit (112) for determining four-dimensional properties of the interface (100) on the basis of the image information formed by said phase shifting interferometric imaging by utilizing effect of the photonic jets. The arrangement also can also comprise means to carry out the measurement using polarized light.

A method involving providing incident radiation of a first polarization state by an optical component into an interface of an object with an external environment, wherein a surface is provided adjacent the interface and separated by a gap from the interface, detecting, from incident radiation reflected from the interface and from the surface, radiation of a second different polarization state arising from the reflection of incident radiation of the first polarization at the interface as distinct from the radiation of the first polarization state in the reflected radiation, and producing a position signal representative of a relative position between the focus of the optical component and the object.
摘要:
A method and apparatus for position control of a component relative to a surface is disclosed. The method may include calculating an estimated effect of, or derived from, Casimir force acting between the component and the surface, and compensating positioning of the component relative to the surface using the estimated effect.
摘要:
An inspection system that is effective to collect images of a part (7) under inspection. This inspection system includes (a) a three axis linear motion stage (10); (b) a rotary fourth axis stage (11) configured to hold and rotate an object (7) to be inspected. This rotary fourth axis stage (11) is mounted on the three axis linear stage (10); (c) a fifth axis camera (1) and optical system (4) mounted to one of the axes of the three axis linear motion stage (10). This fifth axis camera (1) has an optical axis substantially parallel to the axis of linear motion; (d) a 45 degree mirror (6) configured to bend the optical axis of the fifth axis camera (1) by 90° to point towards the object (7); and (e) a motor (3) configured to rotate the mirror (6) over a range of angles to obtain a fifth axis of viewing orientation.
