PROBLEM TO BE SOLVED: To provide a sensing system needed to gather both visible and infrared light, where consolidation of sensors reduces optical complexity and allows creation of a single multifunction semiconductor.SOLUTION: A multispectral staring array 10 comprises, among other things: at least two sensors 28, 30, where each sensor is adapted to detect an image in a different predetermined spectral sensitivity; a first lens 14 to focus and capture incident spectral bands; a spectral filter 20, 22 between the lens and the sensors to subdivide the incident spectral bands; and a second lens 24, 26 to direct and focus the subdivided incident spectral bands onto each of the sensors.

PROBLEM TO BE SOLVED: To provide a virtual microscope system capable of acquiring a photographed image of a dyed sample and a spectral statistical data in a short time. SOLUTION: The virtual microscope system includes an image acquisition section 110 acquiring a 1-band or more dyed sample image of the dyed sample 11; a spectrum acquisition section 130 acquiring a spectrum of one or more predetermined parts of the dyed sample image; an optical path setting section 150 setting an optical path of a luminous flux passing through the dyed sample for the image acquisition section 110 and the spectrum acquisition section 130 so that the spectrum acquisition section 130 can acquire the spectrum of the dyed sample image every time the image acquisition section 110 acquires the dyed sample image; and a control section 210 repeatedly controlling acquisition of the dyed sample image by the image acquisition section 110 and acquisition of the spectrum of the dyed sample image by the spectrum acquisition section 130 in two or more observation fields of the dyed sample 11 so as to create a virtual slide and a spectrum table of the dyed sample 11.

Abstract:
PURPOSE:To enhance the stability of measurement and the efficiency of light, by setting the rotating surface of a chopper at a specified angle other than 90 deg. with respect to the light incident direction, and alternately providing slits for obtaining sample light and mirrors for obtaining reference light. CONSTITUTION:Slits and mirrors are alternately arranged on a concentric circle of a chopper 2. Output light (a) from a laser tube 1 is inputted on the concentric circle. The rotating surface of a rotary body including the concentric circle is arranged at an arbitrary angle other than 90 deg. with respect to the incident direction of the output light (a). When the mirrors 5 and an intermediate region 6 reach the light path, the sample light (a) and reference light (b) are divided into time series. Even though far infrared rays are used, the stability of the measurement and the efficiency of the light can be enhanced in this way.
Abstract:
PURPOSE:To perform spectral photometry in a short time with sufficient measuring accuracy being maintained, by performing time division modulation of the emission from (n) pieces of light sources by the same frequency with the phase being shifted by 360 deg./n sequentially, and simultaneously performing spectral photometry. CONSTITUTION:Light beams emitted from first and second light sources 1 and 2 are modulated by the same frequency so that the phase is shifted by 180 deg. each other by first and second rotary sectors 3 and 4. The light beams are guided to a double monochrometer 8 through a BaSO4 diffuser plate 5 and a mirror 7. The light beams, whose spectrums are divided by the monochrometer 8, which is set at a specified wavelength, are inputted to a photoelectric multiplier tube 9. Its outputs are detected by first and second lock in amplifiers 11 and 12, which are synchronized with the rotary sectors 3 and 4. the measurement is performed by sequentially moving the preset wavelength. Thus the distribution of the spectral emissions of the visual parts from the two light sources 1 and 2 is simultaneously obtained. Therefore the spectral photometry can be performed in a short time, with sufficient accuracy.
