Abstract

The present invention relates to the technical field of digital holographic imaging, and specifically discloses a holographic telescopic device, which comprises: splitting the incident light into two identical light waves through a beam splitter, and reflecting by two concave mirrors with different focal lengths to form two light waves with different phases. The two light waves with different phases are combined by the beam splitter, and self-interference occurs on the surface of the image sensor. The image sensor obtains the complete light wave information (including amplitude and phase) of the light wave of the observed scene by recording the light intensity of the interference fringe, and then realizes three-dimensional observation. The combination of two optical paths is used to achieve interference, and then the three-dimensional detection of the telescopic scene is realized. The utility model has the advantages of simple structure, low cost, and the ability to realize three-dimensional observation.

Description

Technical field [0001] The invention relates to the technical field of digital holographic imaging, in particular to a holographic telescope device and a telescope. Background technique [0002] People can observe distant scenes through telescopes. Traditional telescopes can only observe the light intensity information (amplitude) of the light waves emitted by the scene, but cannot obtain the three-dimensional information. The digital holography technology records the intensity of the interference fringes between the detected object light and the reference light, thereby retaining the phase information of the detected object light. The application of digital holography technology to the telescope can realize three-dimensional imaging of distant objects. [0003] Since the light wave emitted by the detected scene is incoherent light, it cannot interfere with the reference light. But for incoherent light, it is coherent with respect to the light wave itself. For this reason, the ...
