Digital holographic microscopy (DHM) is a method of microscopy in which digital holography is combined with microscopy to enable transparent cells to be visualized with classic cell culture plates. This technology differs from other methods of microscopy in which it does not replicate a projected image of the specimen or sample but instead generates a visual hologram in 2D and 3D views from light waves that have passed through the specimen. In microscopy, digital holographic microscopy (DHM) is applied. Rising demand for digital holography in medical industry for advanced diagnosis is acting as a major driving factor for digital holographic microscopy in medical market. In digital holographic microscopy there is a whole different function in which it does not record the projected image and this is why this function is very much different from other methods. Digital holographic microscopy is very much of its own kind and hence it differentiates itself from others.
What is used in this technology is very unique and time saving as a hologram is recorded digitally when the light waves comes in front. Information originating from the object is digitally recorded and then a computer assumes the object image by using a numerical reconstruction algorithm. That’s why it is totally algorithm based. By a computer algorithm the image forming lens in traditional microscopy is replaced. Other closely relevant microscopy methods to digital holographic microscopy are interferometric microscopy, optical coherence tomography and diffraction phase microscopy.
Common to all methods is the use of a reference wave front to obtain amplitude (intensity) and phase information. The information is recorded by a digital image sensor or a photo detector, from which a computer creates (reconstructs) an image of the object. In microscopy, in which no reference wave front is used, only intensity information is recorded and essential information about the object is lost.
In Europe, the trends have been changing and hence it is affecting many individuals positively and the market is also growing rapidly. In this technique of microscopy there are different types of process type which includes digital recording and reconstruction. The configurations of microscopy are Gabor Holography which is also known as inline holography and then comes the image plane holography, Fresnel holography, Fourier holography and off axis holography. These different types of configuration use different types of technologies. Thus, every configuration is unique.
The digital holographic microscopy in medical market is expected to gain market growth in the forecast period of 2021 to 2028. Researchers have analyzed that the market is growing with the CAGR of 31.8% in the forecast period of 2021 to 2028 and expected to reach USD 263,628.25 thousands by 2028.
