Abstract: An apparatus for providing temperature-dependent movement of an optical element, the apparatus comprising: a moveable mount for the optical element; a mount moving component attached to the moveable mount; and a guide attached to the mount moving component and configured to guide a movement of the moveable mount. The apparatus is configured such that a difference in thermal contraction or thermal expansion between the mount moving component and the guide in response to a change in temperature of the apparatus causes the mount moving component to move the moveable mount relative to the guide.

Abstract: A differential interference imaging system capable of rapidly changing shear direction and amount includes: a light source (101), a filter (102), a polarizer (103), a sample stage (104), an infinite imaging microobjective (105), a tube lens (106), a shear component, an analyzer (113), and an image sensor (114). After the light intensity and a polarization direction is adjusted, the linearly polarized light passes through a transparent sample, to be collected by the infinite imaging microobjective (105) and to implement imaging through the tube lens (106). An imaging beam is divided into two linearly polarized light fields which are perpendicular to each other in the polarization directions and have tiny shear amount, then they are further combined into an interference light filed by the analyzer (103) to form a differential interference image in the image sensor (114). The system may be flexibly assembled, is simple in structure and easy to implement.

Abstract: Systems and methods for hyperspectral and multispectral imaging are disclosed. A system includes a lens and an imaging device having a plurality of pixel sensors. A focus corrector is located within the optical path to refract at least a portion of the incoming light and change the focusing distance of specific wavelengths of light to converge at a focal plane. The focal corrector is selected based upon the imaging system to reduce an overall measure of deviation between a focal length curve for the lens and a focus position curve for pixel sensors to produce focused imaging data for a broad spectrum of light, including beyond the visible range.

Abstract: A spectroscopy system (10) for analyzing in-elastic scattered electromagnetic radiation from an object being irradiated by electromagnetic radiation is provided. The system comprises a tunable lens assembly (13) having a tunable lens provided in the beam path between an electromagnetic radiation source (11) and the object (0) and arranged to project a beam of electromagnetic radiation emitted from the electromagnetic radiation source onto an area of the object and receive and collimate the in-elastic scattered electromagnetic radiation from the object. Based on electromagnetic radiation detected by at least a first detector (121) a control unit (14) is capable making a decision to change the operational settings of the tunable lens.

Abstract: Color information obtained by an optical sensor of a stylus can be displayed at a pen tip of the stylus with good visibility, and visual feedback is provided as a suitable user interface when the color information is transmitted from the stylus to an electronic apparatus. A stylus includes: a trigger signal generating circuit; an optical sensor that detects incident light; a memory circuit that stores color information of the incident light detected by the optical sensor; a color presenting circuit which is disposed at a pen tip of the stylus and which presents a color corresponding to the color information; and a control circuit. The control circuit presents the color information detected by the optical sensor using the color presenting circuit at the pen tip, and controls the color presenting circuit in response to a trigger signal from the trigger signal generating circuit when transmitting the color information to the electronic apparatus.

Abstract: Identifying a location of a focal point of an optical system includes, in some implementations, using a sensor system to detect light that passed through the optical system, and determining a location of a focal point of the optical system based on a location of a focal point of the sensor system that substantially matches the location of the focal point of the optical system.

Abstract: In multiplex CARS, a fingerprint region is a region where signals are densely concentrated. Information about the intensities and spatial distribution of these signals is important in cell analysis. However, there has been a problem in that the signal intensities are low. Accordingly, mechanisms 702 and 703 for adjusting the power branching ratio between light that enters a photonic crystal fiber 705 and pumping light; mechanisms 710 and 711 for adjusting the divergence/convergence state of the pumping light; and mechanisms 706 and 2101 for adjusting the divergence/convergence state of Stokes light are provided to enable adjustment for emphasizing a desired wavelength band.

Abstract: Implementations of the present disclosure relate to a plasma chamber having an optical device for measuring emission intensity of plasma species. In one implementation, the plasma chamber includes a chamber body defining a substrate processing region therein, the chamber body having a sidewall, a viewing window disposed in the sidewall, and a plasma monitoring device coupled to the viewing window. The plasma monitoring device includes an objective lens and an aperture member having a pinhole, wherein the aperture member is movable relative to the objective lens by an actuator to adjust the focal point in the plasma using principles of optics, allowing only the light rays from the focal point in the plasma to reach the pinhole. The plasma monitoring device therefore enables an existing OES (coupled to the plasma monitoring device through an optical fiber) to monitor emission intensity of the species at any specific locations of the plasma.
