Embodiment Construction

[0042] Such as figure 1 and figure 2As shown, it discloses the first preferred embodiment of the optical measurement aid with an elliptical surface structure of the present invention. The optical measurement aid with an elliptic surface structure includes a rotating reflective member 1 and a rotating drive mechanism 2, in:

[0043] The rotating reflective member 1 includes an internal reflection elliptical surface 10, a first focal point 11 and a second focal point 12, the internal reflection elliptical surface 10 is a part of an ellipsoid internal surface and has a reference center Axis 13, that is, an ellipse-shaped inner curved surface is divided into one-Nth (N is a positive integer) block with respect to the reference central axis 13, so that the rotating reflection member 1 has small volume, low material cost, and internal reflection. The elliptical surface 10 is easy to do surface treatment, and the surface is highly accurate; the first focal point 11 and the second ...

Abstract

The invention provides an optical measurement assist device with an oval calotte structure and an optical measurement system. The optical measurement system includes an optical measurement assist device and an optical measurement instrument. The optical measurement system mainly utilizes a first reflection cavity inside provided with an oval calotte inner reflection curve. In another embodiment, a second reflection cavity with an oval calotte inner reflection curve is connected to an end of the first reflection cavity in series. In another embodiment, the reflection oval curve of an oval sphere part is formed through being driven to rotate. By utilizing the oval calotte inner reflection curve, all-directional light beams of a light emitting point can be transmitted to an optical measuring instrument, so that the measurement can be finished quickly. And whole-reflective optical paths can be provided in measurement, and no aberration problems occur. And moving detection is not needed no matter the size of an incoming angle of the light source is and required optical characteristics of a to-be-measured object can be measured.

Description

technical field [0001] The present invention relates to an optical measurement system, especially an optical measurement auxiliary device with an elliptic surface structure in the optical measurement system and an optical measurement system including the optical measurement auxiliary device. Background technique [0002] Items such as liquid crystal display devices must be inspected with an appropriate optical measurement system in order to analyze their optical characteristics, and a specific jig must be used to fix the liquid crystal display device corresponding to an optical measurement instrument for optical measurement operations. Next, the optical characteristics of the liquid crystal display device at various angles are measured at various predetermined angles by using the optical measuring instrument. In order to measure at various predetermined angles, the operator needs to change the position of the optical measuring instrument or liquid crystal display device to d...
