The multi-color off-axis digital holographic system comprises: a plurality of light emitting diodes, for provide a red (R) beam, a green (G) beam and a blue (B) beam; an interference object lens module, for receiving the R, G, and B beams to generate a beam containing an interference signal; a color imaging device, for receiving the beam containing the interference signal and thus forming a hologram on a surface of the color imaging device by holographic interference while registering the hologram; and a processing device, for receiving the registered hologram form the color imaging device; wherein the processing device perform a zero-filling and reconstructing operations upon the received hologram to obtain phase information of the R, G and B beams. With the aforesaid system, a three-dimensional surface profile with respect to a RG synthetic wavelength is obtained according to a calculation using the phase information of the R and G beams as well as the wavelengths thereof, and similarly, a three-dimensional surface profile with respect to a GB synthetic wavelength is obtained according to a calculation using the phase information of the G and B beams as well as the wavelengths thereof. Thereafter, by performing a calculation using the RG synthetic wavelength and its phase as well as the GB synthetic wavelength and its phase, an overall three-dimensional surface profile with respect to a complete synthetic wavelength is obtained.

    摘要： An optical system includes more than two optical interferometers that generate interference phenomena between optical waves to measure a plurality of distances, a plurality of thicknesses, and a plurality of indices of refraction of a sample. An electromagnetic detector receives an output of the optical interferometers to render a magnified image of at least a portion of the sample. A controller reduces or eliminates undesired optical signals through a hierarchical phase unwrapping of the output of the electromagnetic detector.

    摘要： A deep learning-based digital holographic continuous phase noise reduction method for microstructure measurement is provided. A MEMS microstructure is simulated to generate an object phase image through generation of random matrix superposition, noise in a digital holographic continuous phase map is simultaneously simulated to generate a noise grayscale image, and a simulation data set is thus created. An end-to-end convolutional neural network is designed, and a trained convolutional neural network is trained and obtained. A holographic interference pattern of an object under measurement is collected by photographing, and after spectrum extraction, angular spectrum diffraction, phase unwrapping, and distortion compensation, a continuous phase map containing only the object phase and noise is obtained and input into the trained convolutional neural network to obtain an object phase map. A simulation data set is accurately created in the disclosure, thereby the difficulty of collecting a large amount of experimental data is avoided.

    摘要： A holography imaging system includes a first laser, a second laser, a transmitter optical system, a receiver optical system, and a detector array. The first laser has a constant frequency, and the second laser has a non-constant frequency. The transmitter optical system can illuminate a target simultaneously using portions of the first and second laser signals. The receiver optical system can focus a returned light onto the detector array. A first and second illumination point sources can direct portions of the first and second laser signals onto the detector array. The first and second illumination point sources are located in-plane with a pupil of the receiver optical system. The system can detect simultaneously holograms formed on the detector array based on the returned light and the portions of the first and second laser signals directed by the first and second illumination point sources.
