    摘要: The polarization angle θ1 of a polarizer (14) is set, and the reflection intensity S1 in a cross Nicol state and the reference reflection intensity Ref1 of a liquid crystal cell (15) are measured. A different polarization angle θ2 is then set, and the reflection intensity S2 in a cross Nicol state and the reference reflection intensity Ref2 of the liquid crystal cell are measured. The rations S1/Ref1, S2/Ref2 of measured intensities and the ratio S1 · Ref2/S2 · Ref1 is determined in order to cancel the background components of the reference reflection intensities Ref1, Ref2 thus determining the value of cell gap accurately (Fig. 1).

    摘要: The constitution of a probe for measuring light scattering according to this invention is as follows: a light input optical fiber 4 and a scattered light measuring optical fiber 6 for collecting and transmitting scattered light are inserted into a main body of the probe 3; the optical fiber 4 is passed through a hole provided in the probe 3 for measuring light scattering to extend outward; an end portion of each of the optical fibers 4, 6 is covered with a ferrule 66 or 67; an end of each of the ferrules 66, 67 is cut into the shape of a truncated cone such that a part of or the entire end face of the optical fiber 4 or 6 remains; and the ferrules 66, 67 are held by a support body 70 and the like in such a manner that the end faces of the optical fibers 4, 6 are disposed to be adjacent to each other at a predetermined angle with a predetermined distance in between. Accordingly, the end portions of the optical fibers can be reinforced and protected by the ferrules even when they have poor strength. In addition, cutting the ends of the ferrules into the shape of a truncated cone allows the distance between the end faces of the optical fibers to be reduced. (Fig. 2)

    摘要: In an automatic optical measurement method according to the invention, with a movable reflection plate 6 moved to place under an optical axis, light projected from a light projecting portion 3a is received by a light receiving portion 3b via the movable reflection plate 6, a stationary reflection plate 11 and the movable reflection plate 6, whereas with the movable reflection plate 6 moved away from the optical axis and a reference 8 set on a sample stage 10, light projected from the light projecting portion 3a is received by the light receiving portion 3b via the reference 8 whereby a ratio between the intensities of the received lights is determined. During a sample measurement, light projected from the light projecting portion 3a with the movable reflection plate 6 moved to place under the optical axis is received by the light receiving portion 3b via the movable reflection plate 6, stationary reflection plate 11 and movable reflection plate 6 so that the intensity of light thus received and the above ratio are used for estimating an intensity of light to be measured with the reference, the estimated intensity of light being used for correcting an intensity of light received via a sample.

    摘要: A spectral characteristic measurement apparatus (1) includes a spectrometer (24) for spatially dispersing incident light depending on wavelengths and a detection portion (25) for receiving light dispersed by the spectrometer. The detection portion includes a first detection area (25a) on which a component in a first wavelength range is incident and a second detection area (25b) on which a component in a second wavelength range on a longer wavelength side of the first wavelength range is incident. The spectral characteristic measurement apparatus includes a correction portion (100; 226, 228, 230, 232, 234) for correcting stray light detected by the detection portion derived from light to be measured. The correction portion corrects a stray light pattern based on a first amount of change with respect to wavelengths in the first wavelength range of the stray light pattern and a second amount of change with respect to wavelengths included in a result of detection in the first detection area of the detection portion, to calculate a stray light component derived from the light to be measured.
