Abstract: There is provided a laser energy measuring unit whose laser energy measuring range is widened. The laser energy measuring unit has a filter provided within an optical path of laser to attenuate energy of the laser, a calculating section for measuring the energy of the laser passing through the filter and a condenser lens provided on one side of the filter for condensing the laser. The filter has a shading portion for blocking a center part of the laser beam from transmitting through the filter at position coincident with the center of the laser. The center part of the laser where its energy is large is cut by the shading portion and the calculating section measures the part where its energy is not so large. Thereby, it is possible to widen the laser energy measuring range.

Abstract: A correction LED is provided to illuminate a light receiving sensor array, and a calculation controlling circuit calculates correction values at the respective illuminance levels based on sensor output levels expected at the respective illuminance levels and actual sensor output levels while successively turning the correction LED on at a plurality of illuminance levels whose illuminance ratios are at least known, and corrects a sensor output level by the corresponding correction value to obtain a measurement output at the time of an actual measurement. The discontinuity of an input/output characteristic resulting from the switching of gains of an amplifier for amplifying a photocurrent and the non-linearity caused by the saturation of the photoelectrically converting characteristic of the optical sensor and the exponential characteristics of the optical sensor and the amplifier can be corrected without employing a large-scale construction such as a bench. The non-linearity can be highly precisely and efficiently corrected in a measuring apparatus realized as a spectral luminometer or a spectral colorimeter without requiring a special facility.

Abstract: An optical measurement device calibration tool includes an optical probe suitable for calibrating various optical imaging devices, for example, low coherence reflectometers and optical coherence tomography devices. In a preferred embodiment the calibration tool comprises a container containing a calibration substance with stable optical scattering and absorption properties. The calibration substance includes a gel, paste or grease substance and is covered a protective seal, which is at least partially transparent providing optical contact between the optical probe and the calibration substance. The protective seal is covered with a viscous complementary material. Another protective seal made at least partially removable is placed above the viscous complementary material and may serve as a cover for the container. The calibration tool maintains the advantages of calibration tools using liquids and solid states as calibration substance and is more cost-effective and more convenient for calibrating optical measuring devices such as in medical applications.

Abstract: The optical wavelength standard comprises a diffraction grating having a diffractive surface, an input arrangement and an output optical arrangement. The input optical arrangement is located to illuminate the diffractive surface of the diffraction grating with incident light at an angle of incidence at which absorption of the incident light at a resonance wavelength generates surface plasmons. The output optical arrangement is located to receive the incident light specularly reflected from the diffractive surface of the diffraction grating as reflected light. The reflected light includes an absorption line at the resonance wavelength. The absorption line provides the wavelength reference. The resonance wavelength is defined by the angle of incidence and the physical characteristics of the diffraction grating. A desired resonance wavelength can be obtained by appropriately defining the angle of incidence and the physical characteristics of the diffraction grating. Moreover, the resonance wavelength can be changed by changing either or both of the angle of incidence and the diffraction grating.

Abstract: A fiber optic sensing device uses a Fabry-Perot cavity to sense a physical parameter. The cavity modulates the incident polychromatic light. The modulated light is recorded by an optical spectrometer means. The spectrum is analyzed in a signal processing unit which normalizes the spectrum and determines the phase of the modulated signal. The phase, accumulated over whole range of wavelengths, has been used for identification of the physical parameter using a look-up-table. The cavity, the polychromatic light source and the spectroscope means are connected by fiber optic means.
