Abstract: The present invention relates to an inspection apparatus and an inspection method which selectively adjust a numerical aperture of illuminating light in the form of collimated light when inspecting a target object, such as a wafer or the like, using a spectrum, thereby preventing a diffraction phenomenon caused by the illuminating light. The inspection apparatus may include: a camera unit disposed above a target object; an illumination unit configured to illuminate the target object with illuminating light; and a light detection unit configured to detect reflection light of the target object illuminated with the illuminating light, wherein the illumination unit comprises a numerical aperture adjustment device which has a first optical member having a first numerical aperture that is replaceable with a second optical member having a second numerical aperture different from the first numerical aperture so as to reduce a diffraction phenomenon caused by the illuminating light.

Abstract: Described herein are systems and methods for noninvasive functional brain imaging using low-coherence interferometry (e.g., for the purpose of creating a brain computer interface with higher spatiotemporal resolution). One variation of a system and method comprises optical interference components and techniques using a lock-in camera. The system comprises a light source and a processor configured to rapidly phase-shift the reference light beam across a pre-selected set of phase shifts or offsets, to store a set of interference patterns associated with each of these pre-selected phase shifts, and to process these stored interference patterns to compute an estimate of the number of photons traveling between a light source and the lock-in camera detector for which the path length falls within a user-defined path length range.

Abstract: A sample cell apparatus for use in spectroscopic determination of an analyte in a body fluid sample includes a first plate member made from an optically clear material and a second plate member made from an optically clear material and opposing the first plate member. A channel extending into a surface of the first plate member and an opposing surface of the second plate member houses a floating seal. The floating seal surrounds a fluid chamber that retains a sample of body fluid for optical measurement. The fluid chamber may be opened for flushing by separating the first plate member from the second plate member. During measurements the fluid chamber is closed to define a repeatable optical path-length therethrough by urging the first plate member against the second plate member without compressing the floating seal between the first plate member and the second plate member.

The fluid chamber is closed to define a repeatable optical path-length therethrough by urging the first plate member against the second plate member without compressing the floating seal between the first plate member and the second plate member. The seal channel is vented to prevent fluid pressure from flexing the first plate member or the second plate member. An actuator having an extended foot portion extends over the fluid chamber to help prevent flexing of the first plate member or the second plate member.

Abstract: A method is used to determine an absorption behavior of a medium. The method includes establishing an absorption coefficient of the medium using a first intensity value and at least one second intensity value and a length different between a first measurement distance and a second measurement distance. The first intensity value represents a measured first light intensity after passing over a first measurement distance in the medium. The second intensity value represents a measured second light intensity after passing over a second measurement distance in the medium. The first intensity value and the second intensity value are measured using light with a common initial intensity.
