Abstract: An observation device captures images at focal positions inside a sample container with an optical system that includes an objective lens; an objective lens actuator; an irradiation unit; a reflection light intensity detector; a focus controller that positions the focal point of the objective lens on a reflection surface imparting a peak in the reflected light intensity; and a counting unit. The focus control unit drives the objective lens actuator and positions the focal point on a reflection surface when a peak is detected in the reflected light intensity; and the counting unit counts the reflection surface when the focus control unit has positioned the focal point on the reflection surface. The computation unit determines whether or not the focal point is positioned at the focal position, and causes the optical system to capture images if the focal point is positioned at the focal position.

Abstract: The present invention provides a sensor having, one or more optical slab waveguides having one or more target regions. The target regions may interact with gas molecules or trap, entrain or capture one or more targets of interest. The optical slab waveguides are adapted to receive one or more input optical beams from one or more light sources to create a plurality of propagating optical waves in optical slab waveguide. The propagating optical waves interact with said one or more target regions to create an optical output wavefront that may be in the form of a diffraction pattern.

Abstract: It is therefore an objective to provide an object multi-perspective inspection apparatus and a method therefor. The apparatus includes an image capture device; an inspection site and at least two reflection devices, being arranged for reflecting simultaneously to the image capture device at least two different side views of the object located in the inspection site; wherein: the image capture device has a field of view including the at least two different side views of the reflection. By introducing reflection devices into the inspection apparatus to enable the image capture device to “see” the part from multiple views at once, multiple surfaces can be inspected at once, in one image frame, without having the need to reposition the reflection device, the camera and/or the object for every single surface. There are more than one reflection devices placed in the camera's field of view to assist the inspection process by exploiting otherwise hidden surfaces of any given solid object. The effort inspecting every single part form multiple sides is reduced. Therefore, the period of the inspection cycle time can be reduced and inspection on the level of multi-surfaces becomes possible increasing overall quality.

Abstract: MIR spectroscopy systems comprising hierarchical spectral dispersion that enables fine spectral resolution and high sensitivity spectroscopy are disclosed. Hierarchical spectral dispersion is derived by employing at least two diffractive lens arrays, located on either side of a test sample, each receiving input radiation having an input spectral range and distributing the input radiation into a plurality of output signals, each having a fraction of the spectral range of the input radiation. As a result, the signal multiplication factor of the two arrays is multiplied in a manner that mitigates the propagation of wavelength harmonics through the system. In some embodiments, an emitter array comprising a plurality of spectrally selective emitters provides the input MIR radiation to a spectroscopy system. In some embodiments, spectrally selective detectors are used to detect narrow spectral components in the radiation after they have passed through the test sample.
