The first embodiment of acquiring the image signals includes the stage unit 100. ) Is fixed at a constant position and the image acquisition unit 200 acquires the left eye image signal of the subject 10 at a constant position (a) and moves a certain distance to the subject 10 at another constant position (b). By acquiring the right eye video signal of both the left eye video signal and the right eye video signal.

In a second embodiment of acquiring the image signals, the image acquisition unit 200 is fixed, and acquires a left eye image signal of the subject 10 when the stage unit 100 is at a predetermined position (a). When the stage unit 100 moves at a constant distance and is located at another constant position b, the right eye image signal of the subject 10 is acquired. Therefore, both the left eye image signal and the right eye image signal of the subject 10 are acquired.

According to a third embodiment of acquiring the image signals, the image acquisition unit 200 acquires the left eye image signal of the subject 10 at a constant position (a) and moves a certain distance to move the blood at another constant position (b). The right eye image signal of the sample 10 is obtained. On the other hand, the stage unit 100 is opposite to the direction in which the image acquisition unit 200 moves (a-> b) while the image acquisition unit 200 moves while acquiring the left eye image signal and the right eye image signal. Move in the direction (c-> d). That is, since the image acquisition unit 200 and the stage unit 100 simultaneously move in the opposite directions, the image acquisition unit 200 makes the left eye image signal and the right eye image than the first embodiment obtaining the image signals. This has the effect of reducing the time to acquire the signals by half.

The signal processor 300 converts the image signals input from the image sensor 220 into image data that can be read by the stereoscopic image display unit 400, and converts two image data of left eye image data and right eye image data.

The display devices 410 and 420 are formed by attaching polarization filters 412 and 422 having the same polarization angle to 45 degrees on the front of the display panels 411 and 421, respectively.

In addition, the display panels 411 and 421 may be provided as an LCD liquid crystal panel, a plasma display panel (PDP) panel, or an organic light emitting diode (OLED) panel. In the stereoscopic microscope according to the first embodiment of the present invention, the display panel 411 and 412 were all equipped with LCD liquid crystal panel.

In general, the LCD liquid crystal panel has a polarizing filter attached to the front and is manufactured as one display device. Therefore, the polarizing filter does not need to be attached again. However, since the polarizing filter is not attached to the PDP panel or OLED panel, the polarizing filter should be attached to the front. .

In addition, the display devices 410 and 420 may be manufactured by attaching a polarization filter having a polarization angle of 135 degrees to the front of the display panels 411 and 421.

In addition, the first display device 410 and the second display device 420 may be manufactured by attaching a polarization filter having a front polarization angle of 90 degrees, 0 degrees, 0 degrees, or 90 degrees, respectively.

As a result, the polarization angle of the polarization filter is sufficient so that when the left and right images are simultaneously formed on the half mirror 430, the polarization angles of the images form 90 degrees to each other.

However, even though the polarization angles of the left eye image and the right eye image formed on the half mirror 430 are not necessarily 90 degrees, the left eye image and the right eye image having different polarization angles are formed on the half mirror 430 to separate the polarization angles. If the polarizing glasses 20 are visible, the viewer can observe the stereoscopic image.

The first display apparatus 410 receives left eye image data from the signal processor 300 and displays a left eye image.

The second display apparatus 420 receives the right eye image data from the signal processor 300 to display the right eye image, and the lower front portion forms an edge with the front lower portion of the first display apparatus 410 at a predetermined angle. . Preferably it is installed at 90 degrees. However, the predetermined angle may be changed according to the refractive index and the reflectance of the half mirror 430 provided between the display devices 410 and 420.

In addition, the right eye image may be displayed on the first display apparatus 410 and the left eye image may be displayed on the second display apparatus 420.

In the stereoscopic microscope according to the first embodiment of the present invention, the image of the first display apparatus 410 is transmitted by the half mirror 430 and the image of the second display apparatus 420 is reflected. However, the image of the first display apparatus 410 may be reflected and the image of the second display apparatus 420 may be transmitted.

The half mirror 430 is a mirror that transmits light on one side and reflects light on the other side, and is also called a translucent mirror.

In addition, it is provided while maintaining a constant angle between the display devices (410, 420), and preferably provided with maintaining an angle of 45 degrees with the display devices (410, 420), respectively.

However, the angle of 45 degrees may be changed according to the refractive index and the reflectance of the half mirror 430 and the left and right images displayed on the display devices 410 and 420 may be simultaneously formed on the half mirror 430 without being distorted. It is enough if you can.

The image reversing circuit 440 inverts the image of the display apparatus for illuminating the image on the reflective surface of the half mirror 430 among the display apparatuses 410 and 420.

The reason is that since the reflection surface of the half mirror 430 is like a mirror, the image of the display device that is illuminated is inverted in left and right directions.

 In the stereoscopic microscope according to the first exemplary embodiment of the present invention, since the right eye image of the second display apparatus 420 is reflected by the half mirror 430, the image inversion circuit 440 of the second display apparatus 420 Inverts the right eye image from side to side.

Since the half mirror 530 has a three-dimensional image having a polarization angle of 90 degrees to each other.

However, when the front and rear polarization angles are 0 degrees, 90 degrees, 90 degrees, or 0 degrees, respectively, the front polarization angle of the third display apparatus 510 and the front polarization angle of the fourth display apparatus 520 are the same. However, the half mirror 430 has a left eye image and a right eye image having a polarization angle of 90 degrees.

Accordingly, the image and polarization of the third display apparatus 510 are transmitted to the half mirror 430, and the image and polarization of the fourth display apparatus 520 are reflected and inverted. It can achieve the same effect as 400).
