We present a novel technique that is capable of a 3D volumetric imaging without moving an observed plane in a framework of fluorescent laser scanning microscopy. Our method is based on a 2D scanning of a Bessel beam exhibiting an optical needle spot with a long depth of focus (DOF). In addition, we utilize the non-diffracting and self-bending characteristics of an Airy beam for detection to extract the depth information of the image. In our method, 3D image construction with depth discrimination can be expected by using Airy beam conversion for detection in laser scanning microscopy with optical needle spot scanning.
