Patent
Confocal type laser scan microscope with integrated illumination, detection and waveguide system
TL;DR: A confocal type laser scan microscope comprises a substrate including a first channel wave guide having a first end and having the other end connected to a connecting port of a mode splitter as discussed by the authors.
Patent
Optical waveguide device and optical microscope using the same
TL;DR: In this paper, an optical waveguide was used in place of a pinhole element in an optical system of a confocal scanning optical microscopes to guide illuminating light to an object to be detected and to guide the reflected light from the object into a detector.
Patent
Structured illuminating microscopy apparatus
TL;DR: An acquiring unit of a structured illuminating microscopy apparatus acquires at least two modulated images having the same wave number vector and the different phases; and a calculating unit, in a spatial frequency spectrum of each of at least the two modulating images acquired by the acquiring unit, separates a 0th-order modulating component and ± first-order modulation components of observational light fluxes superimposed on arbitrary two observation points based on at least four observation values regarding the two observations points which are mutually displaced by an amount of the wave number vectors as mentioned in this paper.
Patent
Optical integrated device for magneto-optical reproducing head
TL;DR: In this paper, a device consisting of five wave guides and two interposed TE-TM mode splitters, formed on a substrate, is described, and the signal light beam is further split by the second mode splitter and directed to the fourth and fifth wave guides, thence to external detectors.
Patent
Confocal laser scanning microscope with dual mode waveguide
TL;DR: In this article, a double-mode transmission waveguide was proposed to detect the amplitude distribution of the electric fields in the two directions of the reflected light from the object according to amplitude distributions of electric fields.
