Abstract

In a method for operating a microscope, a lens unit transmits a first image laser to an object, and acquire a first scan image on the basis of a first reflection signal reflected from a first area included in the object. An ultrasound conversion unit transmits an ultrasound signal to the first area and focuses same so as to form air bubbles in the first area. The lens unit transmits a second image laser to the object, and can acquire a second scan image on the basis of a second reflection signal reflected from the second area included in the object. The ultrasound conversion unit transmits an ultrasound signal to the first area included in the object and focuses same so as to form air bubbles in the first area, thereby enabling an increase in the imageable depth of a microscope.

First claim

The invention claimed is:

1. A method of operating a microscope, the method comprising:
transmitting a first image laser to a target and acquiring a first scan image based on a first reflection signal reflected from a first region included in the target by a lens unit;
transmitting and focusing an ultrasound signal onto the first region to form air bubbles in the first region by an ultrasound conversion unit; and
transmitting a second image laser to the target and acquiring a second scan image based on a second reflection signal reflected from a second region included in the target by the lens unit.

2. The method according to claim 1 , wherein
the lens unit is disposed in a first direction relative to the target, and the ultrasound conversion unit is disposed in the first direction relative to the target.

3. The method according to claim 1 , wherein
the lens unit is disposed in a first direction relative to the target, and the ultrasound conversion unit is disposed in a second direction relative to the target.

4. The method according to claim 1 , further comprising determining whether the air bubbles have been formed in the first region.

5. The method according to claim 4 , wherein, upon determining that the air bubbles have not been formed in the first region, the ultrasound conversion unit focuses and retransmits an ultrasound signal to the first region.

6. The method according to claim 1 , wherein an area of the second region varies depending on a size of each of the air bubbles.

7. The method according to claim 6 , wherein the area of the second region is increased as the size of each of the air bubbles is increased.

8. The method according to claim 7 , wherein the size of each of the air bubbles varies depending on a magnitude, pulse width, and pulse repetition time of the ultrasound signal.

9. The method according to claim 1 , further comprising synthesizing the first scan image and the second scan image to acquire a synthetic image for the first region and the second region.

10. A microscope device comprising:
a lens unit configured to transmit a first image laser to a target, to acquire a first scan image based on a first reflection signal reflected from a first region included in the target, to transmit a second image laser to the target after air bubbles are formed in the first region, and to acquire a second scan image based on a second reflection signal reflected from a second region included in the target; and
an ultrasound conversion unit configured to transmit and focus an ultrasound signal onto the first region to form the air bubbles in the first region.

11. The microscope device according to claim 10 , wherein
the lens unit is disposed in a first direction relative to the target, and the ultrasound conversion unit is disposed in the first direction relative to the target.

12. The microscope device according to claim 10 , wherein
the lens unit is disposed in a first direction relative to the target, and the ultrasound conversion unit is disposed in a second direction relative to the target.

13. The microscope device according to claim 10 , wherein, in a case in which the air bubbles have not been formed in the first region, the ultrasound conversion unit focuses and retransmits an ultrasound signal to the first region.

14. The microscope device according to claim 10 , wherein the microscope device synthesizes the first scan image and the second scan image to acquire a synthetic image for the first region and the second region.

15. A method of operating a microscope, the method comprising:
transmitting and focusing an ultrasound signal onto a first region included in a target to form air bubbles in the first region by an ultrasound conversion unit; and
transmitting an image laser to the target and acquiring a scan image based on a reflection signal reflected from the first region and a second region included in the target by a lens unit.

16. A microscope device comprising:
an ultrasound conversion unit configured to transmit and focus an ultrasound signal onto a first region included in a target to form air bubbles in the first region; and
a lens unit configured to transmit an image laser to the target and to acquire a scan image based on a reflection signal reflected from the first region and a second region included in the target.
