Also, due to –OH group, it has the ability to form hydrogen bonds.Įthanol is used as a beverage. According to the ethanol percentage, there are different types of beverages such as wine, beer, whiskey, brandy, arrack, etc. Ethanol can be easily obtained by the sugar fermentation process using zymase enzyme. This enzyme naturally presents in yeast, so in the anaerobic respiration, yeast can produce ethanol. Ethanol is toxic to the body, and it is converted to acetaldehyde in the liver, which is also toxic. Other than a beverage ethanol can be used as an antiseptic to clean surfaces from microorganisms, and it is mainly used as a fuel and a fuel additive in vehicles. Isopropyl has three carbon atoms, and ethanol has only two carbon atoms.Ethanol is stable, and isopropyl is not stable.Ethanol is an organic molecule and isopropyl is only a part of organic molecule.Ethanol is miscible with water, and also it serves as a good solvent. In ethanol, there is an oxygen atom instead of hydrogen and carbon.The Compressive Sensing (CS) is an emergent theory that provides an alternative to Shannon/Nyquist Sampling Theorem. By CS, a sparse signal can be perfectly recovered from a number of measurements, which is significantly lower than the number of periodic samples required by Sampling Theorem. The THz radiation is nowadays of high interest due to its capability to emphasize the molecular structure of matter.

In imaging applications, one of the problems is the sensing device: the THz detectors are slow and bulky and cannot be integrated in large arrays like the CCD. The CS can provide an efficient solution for THz imaging. This solution is the single pixel camera with CS, a concept developed at Rice University that has materialized in several laboratory models and an IR camera released on the market in 2013.
