Abstract:
A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.

Abstract:
In general, an imaging system to synchronously record a spatial image and a spectral image of a portion of the spatial image is described. In some examples, a beam splitter of the imaging system splits an optical beam, obtained from a viewing device, into a first split beam directed by the imaging system to a spatial camera and a second split beam directed by the imaging system to the entrance slit of an imaging spectrograph that is coupled to a spectral camera. An electronic apparatus synchronously triggers the spatial camera and the spectral camera to synchronously record a spatial image and a spectral image, respectively.

Abstract:
The present invention relates to a device for the discrimination of biological tissues, such that it is capable of carrying out the discrimination of tissue under complicated operating conditions, for example due to the presence of contaminating elements given off by a cutting operation, due to the presence of moisture in the biological tissue, or due to the presence of a non-controlled atmosphere that interferes with the results of the readings. The invention allows building more complex devices, including cutting instruments, such that it is possible to carry out a surgical intervention in a safe manner by preventing cutting into tissues that are to be avoided during said cutting operation.
