Abstract: Provided is a sample property detecting apparatus including: a wave source configured to irradiate a wave towards a sample; a detector configured to detect a laser speckle that is generated when the wave is multiple-scattered by the sample, at every time point that is set in advance; and a controller configured to obtain a temporal correlation that is a variation in the detected laser speckle according to time, and to detect properties of the sample in real-time based on the temporal correlation, wherein the detector detects the laser speckle between the sample and the detector or from a region in the detector.

Abstract: An apparatus and method for detecting microbes use laser speckles. The apparatus includes a light source configured to irradiate light into a sample to detect microbes, and a measuring part configured to measure laser speckles, which are formed due to a multiple scattering of the light which is incident into the sample, every reference time and to measure concentration of the microbes contained in the sample based on temporal correlation of the measured laser speckles.

Abstract: Disclosed herein are an apparatus and method for forming a 3D holographic image using non-periodically structured optical elements. The 3D holographic image apparatus includes a light source configured to radiate light, a spatial light modulator configured to modulate the light projected by the light source, and a non-periodic optical element configured to modulate incident light by refracting, diffracting or reflecting the direction of the incident light in a plurality of directions when the light modulated by the spatial light modulator is incident. A 3D holographic image may be formed based on the light modulated by the non-periodic optical element.
