  • Publication number: 20170251149
    Abstract: The present invention discloses a method of determining a whole-scene image by using multiple image-capturing devices, and the method has two main features including non-contact formation digital image method and the parallax elimination process for captured images. The former feature uses a concyclic fitting calculation to easily determine the locations and orientations of the image-capturing devices, so as to achieve the objective of assisting in capturing the whole-scene image. The latter feature can effectively improve the image quality, so as to effectively solve the problems in conventional technology.

  • Publication number: 20170154418
    Abstract: A method is provided to label invisible fluorescence by a visible light. A surgeon gets rid of screen for direct observation without repeated location confirmations between surgical site and onscreen mark. Fluid movement of a fluorescent dye can be observed in a real-time mode. Through projecting a visible-light spot at a fluorescent area at real time, the surgeon observes the fluorescent area the visible-light spot projecting to. Hence, the problem that fluorescence imaging technology must rely on screen to see the location of the fluorescent area is solved. When a patient moves or fluorescent areas changes, an image sensor automatically adjusts an area labeled by a visible-light spot through changing a photographing area with a focus automatically set. In addition, the method adjusts a projecting angle of the visible-light spot with an initial mirror and a final mirror only. Adjustment of lens group is not required the saving money.

  • Patent number: 9644947
    Abstract: A device for real-time thickness inspection is provided. An optical interferometric technique is used. Measurement requirements in rapid online thickness inspection can be satisfied. An object is measured in a non-contact and non-destructive way. For measuring, an optical spherical wavefront is radiated on the object in an oblique angle. The interference fringe pattern (IFP) thus imaged on a screen is directly related to the thickness distribution of the object. The phase difference on the same horizontal cross section in the IFP monotonically decreases from the light source side to the other side. Accordingly, phase unwrapping can be effectively performed without using phase shift. The present invention achieves rapid on-line thickness inspection through the optical path of interference without using optical lens groups and special optical elements.

  • Publication number: 20170016769
    Abstract: The present invention provides a measurement system of real-time spatially-resolved spectrum and time-resolved spectrum and a measurement module thereof. The measurement system includes an excitation light and a measurement module. The excitation light excites a fluorescent sample and the measurement module receives and analyzes fluorescence emitted by the fluorescent sample. The measurement module includes a single-photon linear scanner and a linear CCD spectrometer. The single-photon linear scanner selectively intercepts a light beam component of a multi-wavelength light beam that has a predetermined wavelength to generate a single-wavelength time-resolved signal, wherein the multi-wavelength light beam is generated by splitting the fluorescence. The linear CCD spectrometer receives the multi-wavelength light beam and generates a spatially-resolved full-spectrum fluorescence signal.

  • Patent number: 9398286
    Abstract: A multi-image capture device capturing images by means of circular motion controls the shift movement, along a semi-circular measuring rod, of a moving mechanism by a location control device. Furthermore, a rotary control device is used to control the positioning and image-capturing angle of a second image capture device fixed on the rotary mechanism. Thereby, a first image capture device and the second image capture device are of a co-circle configuration where the optical axis of the first image capture device and the second image capture device overlap to form a center of the co-circle. Such a configuration can broaden the visual range of the image capture device, and allows quick calibration of the image capture device according to positioning of shift movement and image-capturing angles.

  • Patent number: 9116854
    Abstract: An image correlation for images having speckle pattern is evaluated. Modulation transfer function (MTF) curves of speckle-pattern images captured at different times are figured out. Whether a correlation value between the MTF curves meets a threshold is checked. If the correlation value is smaller than the threshold, speckle-pattern images are re-selected for re-figuring out the MTF curves and the correlation value. Thus, error of strain and displacement for digital image correlation owing to blurring images of the on-moving target object is figured out; calculation time of the digital image correlation is reduced; and accuracy on measuring physical parameters of the target object before and after movement is improved for digital image correlation.
