Setting

Setting of Synchronization

The synchronized measurement refers to measurement mode where measurement is made in the same timing as periodical light source pulse frequency, such as vertically synchronized frequency for the display device.

[INT SYNC]

The internal sync measurement mode is used to measure the display equipment without the input of vertically synchronized signals to the body, or to measure flicker light from a light source such as a fluorescent light. Input the frequency of vertically synchronized signals for the display equipment, or the commercial frequency (50 or 60 Hz) for flicker light from a light source such as a luminescent light. The optimal integral action time is automatically set based on the input value and the brightness of the object. For this reason, enter the correct frequency value to two places of decimals.

However, if the vertically synchronized frequency of the display equipment is not clear, accurate measurement will not be possible with an inaccurate frequency setting. In this case it is recommended to select [NO SYNC] mode without sync measurement (at 60 Hz of frequency), but to select [MULTI INTEG] mode for the measurement time (refer to p. 30).

[EXT SYNC]

The external sync measurement mode is used to measure the display equipment after the line input of a vertically synchronized signal through the input terminal for vertically synchronized signals to the body. The optimal integral action time is set automatically, based on the frequency of vertically synchronized signals and the brightness of the object. Input CMOS (5V) Level of the input signals.

• Range of synchronized frequencies : 20.00 to 200.00 Hz
• Factory default setting : NO SYNC

Explanation

Measurement Principle

Light energy passes through the objective lens. The lights from the measurement area pass through the hole in the center of the aperture mirror to the optical fiber, while the remaining light is guided to the finder optics by the aperture mirror. As a result, the part equivalent to the measurement area looks like a black circle when observed through the finder.

The light entering the optic fiber is reflected repeatedly so that it is mixed and becomes virtually uniform. It then passes through the collimator lens to the plane diffraction grating. After being dispersed by the grating, the light is focused by the condenser lens according to wavelength. An array sensor is located at this focus point.

The amount of detected energy for each wavelength is then converted to a digital value by an A/D converter, based on which the spectral radiant luminance and chromaticity are calculated by the processing section of the CS-2000.

Sensor Section

The sensor section has a photo diode array consisting of 512 elements. The array is always kept at constant temperature using a Peltier cooler, irrespective of the ambient temperature. This can reduce dark current and improve S/N ratio, thus enabling

measurement of low luminance.

Dark Measurement

Each measurement consists of "light measurement" and "dark measurement".

"Light measurement" is performed with light from the object irradiating the sensor, while "dark measurement" is performed with no light from the object irradiating the sensor, so that detector dark current is measured.

When measurement starts, first "light measurement" is performed. When "light measurement" is complete, the shutter will close automatically, then "dark measurement" starts immediately. "Dark measurement" is performed with the same integration time used for "light measurement".

The final measured data is obtained by subtracting the measured data obtained in "dark measurement" from the one obtained in "light measurement". This method eliminates influences of dark current of the array sensor, resulting in improved measurement accuracy.

Following factors can be acquired as measurement value with L_vT uv as color space of this instrument.

T :Correlated color temperature

Δuv :Color difference from blackbody locus

While L_vs stands for luminance, T and u v for color in L_vT u v

Color temperature refers to the temperature of black body (perfect radiator) which has equal chromaticity coordinates to certain light. However, color temperature only represents colors on blackbody locus.

Correlated color temperature, slightly wider interpretation of color temperature, is very useful to eliminate such problem. Here, correlated color temperature covers those which are slightly outside the range of that of blackbody locus.

If a certain color positions on isotemperature line, the intersection point of isotemperature line and blackbody locus is indicated as correlated color temperature for the color.

Isotemperature line means line on chromaticity coordinates which is a set of colors visually close to color temperature on blackbody locus.

However, since all colors on a color-matching temperature line are represented with equal correlated color temperature, it is not possible to describe color only with correlated color temperature. To solve that, u v , deviation of correlated color temperature T from blackbody locus, is to apply for that purpose.

If u v exists above blackbody locus, it is represented with ^ 一 + ^ 一 , and below, with -

Dominant wavelength/Excitation purity

In the x, y chromaticity diagram shown below, the curve VScSR is the spectrum locus, and point N is the white point (the chromaticity point of the perfect reflecting diffuser).

Colors located in the region enclosed by the spectrum locus and the straight lines VN and NR are referred to as spectral colors; colors located in the triangle NVR with the white point N at the apex and the pure purple line VR as the base are referred to as nonspectral colors.

When the chromaticity point obtained by the measurement is C, the wavelength corresponding to the intersection point S of the extension of NC with the spectrum locus (curve VScSR) is referred to as the dominant wavelength and indicated by the symbol _d . The ratio of the lengths of the straight lines NC and NS is referred to as the excitation purity of color excitation C and indicated by the symbol p_e .

When the chromaticity point obtained by measurement is C' , the extension of NC' toward C' does not intersect with the spectrum locus but only the pure-purple lines. In this case the wavelength corresponding to the intersection point S_c of the extension of NC' toward N with the spectrum locus is referred to as the complementary wavelength and indicated by the symbol c . When the intersection point of the extension of the line NC' with the line VR (pure-purple locus) is designated by S' , the ratio of the lengths of NC' to NS' is referred to as excitation purity and indicated by the symbol p_v' .

The following equations are formulated, if each point is designated as the following coordinates: (xn,y_n) : chromaticity coordinate of point N; (xc,yc) : chromaticity coordinate of point C; (x,y) : chromaticity coordinate of point S, (xc^,yc) : chromaticity coordinate of point C', and (xp,y_p) : chromaticity coordinate of point:

Excitation purity (spectral colors)

$$ p _ {e} = \frac {x _ {c} - x _ {n}}{x - x _ {n}} = \frac {y _ {c} - y _ {n}}{y - y _ {n}} $$

Excitation purity (non-spectral colors)

$$ p _ {e} ^ {\prime} = \frac {x _ {c} ^ {\prime} - x _ {n}}{x _ {p} - x _ {n}} = \frac {y _ {c} ^ {\prime} - y _ {n}}{y _ {p} - y _ {n}} $$
