Abstract
The utility model discloses a color observing system which comprises a diffused reflection device. The diffused reflection device comprises a hollow cavity body; and a plurality of openings passing through the cavity body are formed on the cavity body and are connected with a light source or a measuring device through a light transmission device. Because the small diffused reflection device is adopted, the color observing system can realize color observation in tiny areas, and the measuring results thereof and the measuring results under the standard conditions are identical or approximate after being corrected.
Description
Technical field
The utility model relates to a kind of color recording geometry, can realize the color observation of d/0 condition, and be that a kind of light path volume is little, can carry out the system of color observation to tiny area.
Background technology
The d/0 observation condition is one of color observation condition of CIE (Commission International d ' Eclairage is called for short CIE) recommendation, and it uses diffuse illumination, right-angle view.
In practice, often use d/8 condition similarly, i.e. diffuse illumination, 8 ° of observations.At this moment, the direct reflection of comprising and do not comprise two kinds of conditions of direct reflection is arranged again.
The realization of above-mentioned measuring condition all needs to use integrating sphere.In practice, integrating sphere is subjected to the restriction of its structure, measures the main part of light path, often can not be very little.This has limited the color measuring of the inside of its usable range, particularly some little implements.For example, some ceramic historical relic.
When using off-gauge measuring condition, structure and volume design can be more flexible, might realize the measurement light path that volume is small and exquisite.
Utilize the canonical measure condition of integrating sphere, can realize the absolute measurement of light diffuse reflectance, also can realize comparing and measuring of light diffuse reflectance.All use the diffuse reflectance measurement of non-standard condition, can only realize comparing and measuring of light diffuse reflectance, need relative diffuse reflectance numerical value be converted into the absolute figure of diffuse reflectance by reference standard and mathematical method.Comparing and measuring and bearing calibration, all is very ripe perfect technology, and routinized (list of references: " modern color technical principle and application ", p317, p321-17, Hu Weijie etc., publishing house of Beijing Institute of Technology, Beijing, 2007.).
In view of this, need a kind of system that can realize the color observation that volume is little.
The utility model content
The utility model utilizes a kind of diffuse device, realizes that a kind of light path volume is little, and can carry out the system of color observation to tiny area.
The technical solution of the utility model is summarized as follows:
A kind of color recording geometry is characterized in that, comprises a diffuse device, and described diffuse device comprises the cavity of a hollow, has some perforates that run through cavity on the described cavity; Described perforate connects light source or measurement mechanism by the light conduction device.
