Abstract
A machine learning-based digital holography device and a method for operating same are disclosed. The digital holography method according to one embodiment comprises the steps of: obtaining an optical image including two-dimensional information about a sample; and on the basis of the optical image, generating a holographic image including three-dimensional information about the sample.
Claims12
A digital holographic method including:
- obtaining a bright-field (BF) image comprising two-dimensional (2D) information of a sample;
- and
- generating a hologram image comprising three-dimensional (3D) information of the sample by inputting the BF image to a neural network, the neural network being trained by statistically learning a relationship between a training BF image according to a depth of a training sample and a corresponding training hologram image of the training sample.
A digital holographic apparatus comprising:
- a memory containing instructions;
- and
- a processor configured to execute the instructions,
- wherein, when the instructions are executed by the processor, the processor is configured to:
- generate a hologram image comprising three-dimensional (3D) information of a sample by inputting bright-field (BF) image comprising two-dimensional (2D) information of the sample to a neural network, the neural network being trained by statistically learning a relationship between a training BF image according to a depth of a training sample and a corresponding training hologram image of the training sample.
