  • Patent number: 6835933
    Abstract: A spectrum measuring apparatus for measuring infrared, Raman and fluorescence spectra. The spectrum measuring apparatus includes an infrared source, a laser source, an infrared up-conversion object lens, an object lens, a dual color lens, an ocular, a narrow band filter, a visible light image capturing device and a sample pedestal. The infrared spectrum is measured by the infrared up-conversion object lens. The Raman and fluorescence spectra are measured by the object lens.

  • Patent number: 6687051
    Abstract: A microscopic image apparatus for converting infrared light into visible light. The microscopic image apparatus includes a sample stage, an infrared source, an object lens for converting infrared light into visible light, a visible light source, a dichroic mirror, a visible light imaging lens and a visible light image capturing device. The object lens further includes an optical crystal and an infrared object lens. After the infrared source outputs infrared light to a sample placed on the sample stage, the object lens converts infrared light spectrum image into visible light spectrum image. Then, the visible light spectrum image is obtained by the visible light imaging lens and the visible light image capturing device.

  • Publication number: 20030122058
    Abstract: An image-sensing method uses a modulated light as the light source. The image sensing method comprises the steps of using the modulated light to a sample to generate a modulated light signal, transmitting the modulated light signal to a light sensing element to convert the modulated light signal to an AC image signal, transmitting the AC image signal to an AC/DC conversion circuit to convert the AC image signal to a DC image signal according to the modulation frequency of the modulated light and forming the DC image signal. The image-sensing method effectively prevents interference of stray light and electronic noise.

  • Patent number: 5243317
    Abstract: A digitizer whose sensing elements are made of magnetoresistive materials is designed for use with a computer system. The digitizer board includes a substrate made of dielectric material; a first array of strip-shaped magneto-resistors arranged on the front surface of the substrate; a second array of strip-shaped magneto-resistors arranged on the reverse surface of the substrate; a plurality of analog comparators coupled to the magneto-resistors; and a pen with a magnetic pinpoint used for pointing to a particular location on the front side of the digitizer board. The resistance of the magneto-resistors will vary due to a magnetic field emerging from the nearby pinpoint, and the magnetic-resistors will be effected, and subsequently the comparators connected to the magneto-resistors will send digital signals to the computer system.
