A multi-mode optical fiber delivers light from a radiation source to a multi-focal confocal microscope with reasonable efficiency. A core diameter of the multi-mode fiber is selected such that an etendue of light emitted from the fiber is not substantially greater than a total etendue of light passing through a plurality of pinholes in a pinhole array of the multi-focal confocal microscope. The core diameter may be selected taking into account a specific optical geometry of the multi-focal confocal microscope, including pinhole diameter and focal lengths of relevant optical elements. For coherent radiation sources, phase randomization may be included. A multi-mode fiber enables the use of a variety of radiation sources and wavelengths in a multi-focal confocal microscope, since the coupling of the radiation source to the multi-mode fiber is less sensitive to mechanical and temperature influences than coupling the radiation source to a single mode fiber.

PURPOSE: To compensate a measuring error due to a humidity difference and a temperature difference by subtracting an influence portion due to the humidify difference and the temperature difference of a standard gas and a gas to be measured and the offset component of an odorant sensor from the output of the odorant sensor. CONSTITUTION: The characteristic of an odorant sensor 5 is decided in such a way that a function f 1 which depends only on the concentration (c) of an odorant substance and a function which corresponds to a change and a change with the elapsed time due to temperature and humidity are added. A changeover means 2 changes over the connection to supply the output of a standard-gas generation means 1 to a measuring cell 4, the temperature and the humidity of a standard gas are measured by sensors 6, 7, and an arithmetic circuit 10 operates and outputs an influence portion due to a temperature difference and a humidity difference so as to be 0. A subtraction circuit 11 to which values are input from the sensor 5 and the circuit 10 subtracts them, and an output 102a becomes 0. Then, the means 2 changes over the connection to feed gas to be measured 4 from an inlet 100, the circuit 10 operates an influence portion due to the temperature difference and the humidity difference of the standard gas and a gas to be measured, it is subtracted by the circuit 11 in the same manner, and the output 102a≈f 1 (c) is output. Consequently, the output depends only on the concentration of the odorant substance. COPYRIGHT: (C)1995,JPO

Gas measuring apparatus

PURPOSE:To measure a frequency change even with a counter having a small number of bits by subtracting new measured value from preceding new measured value by (n) and dividing the cumulative difference by (n). CONSTITUTION:A sensor 1 which sucks smells, etc., and the resonance frequency of which changes is set in a gas to be measured and resonates when an oscillation circuit 2 is driven. A counter 11 inputs the resonance frequency signal of the sensor 1 and measures the frequency of the signal. A storage circuit 13 and subtracting circuit 14 input the measured value of the counter 11. The circuit 13 stores past (n) measured values and, when a new measured value is inputted, outputs the oldest value among the storing measured values, namely, the measured value preceding the new measured value by (n) measured values to the circuit 14. The circuit 14 subtracts the oldest measured value from the new measured value and outputs the difference to an adding circuit 15 and the circuit 15 adds the output signal of the circuit 14 to a cumulative value stored in a storage circuit 16 and stores the new cumulative value in the circuit 16. Then a dividing circuit 8 divides the output signal of the circuit 16 by (n) and a frequency converting circuit 9 converts the output of the circuit 8 into a frequency value from the count value and outputs a signal 100a.

Frequency change measuring instrument

PURPOSE: To provide a densitometer for measuring the density of each phase of a multiphase fluid accurately through simple structure by determining the volume ratio among respective phases based on the dielectric constant depending on the frequency. CONSTITUTION: A multiphase fluid mixed with water oil or gas flows through a duct 10 in the direction shown by an arrow Y and passes between the electrodes 21a, 21b of a multiphase densitometer 20. In the multiphase densitometer 20, a high frequency sine wave having variable frequency is applied from an impedance measuring circuit 22 between the electrodes 21a, 21b secured to the duct 10 and the capacitive impedance between the electrodes is measured. Since a predetermined relationship is satisfied between the dielectric constant of a dielectric and the capacitance between the electrodes, the density of the fluid can be determined for each phase by measuring the variation in the capacitance, i.e., impedance, for each phase of water, oil or gas when the frequency is varied and then determining the volume ratio among respective phases through an arithmetic circuit 23.

PROBLEM TO BE SOLVED: To provide a confocal microscope system that can display a slice image at a designated Z position as a live image after completing fetching one three-dimensional image when a sample is repeatedly three-dimensionally measured. SOLUTION: The confocal microscope system includes steps of: irradiating a sample with a laser beam which is input to a confocal scanner via an objective lens of a microscope; and fetching a confocal image of the returned fluorescent light from the sample as a three-dimensional slice image while the focus position of the objective lens is shifted toward the focus. The system is equipped with a Z-position image processing means which makes the focus position of the objective lens shift to a specified Z position toward the focus during a halt period in the cycle time of three-dimensional measurement, and which displays a slice image of the sample at the current Z position.
