According to an embodiment, a holographic microscope comprises a light source, an optical system splitting light emitted from the light source into an object and a reflective mirror and inducing interference between light reflected by the object or transmitted through the object and light reflected by the reflective mirror, a first image sensor receiving the interference light and sensing interference information for the interference light, a second image sensor receiving the light reflected by the object or transmitted through the object and sensing information for the received light, and an image processor deriving a shape of the object based on the interference information sensed by the first image sensor and the information sensed by the second image sensor.

Holographic microscope

According to an embodiment, a holographic microscope comprises a light source emitting light to an object, a beam splitter reflecting the light emitted from the light source to the object and transmitting object light reflected from the object, a holographic image sensor sensing information, including a holographic image, by receiving the object light and allowing the object light to coherently interfere with reference light, and an image processor obtaining three-dimensional (3D) information about the object based on the information sensed by the holographic image sensor. The holographic image sensor includes a lens focusing the object light to the holographic image sensor, a filter transmitting a predetermined wavelength band of light of the focused object light, a light receiving unit receiving interference light to sense a holographic image, and a reference light source directly emitting the reference light having the predetermined wavelength band to the light receiving unit.
