What is Picosecond?

Picosecond is one trillion a second. It is the rate of time that comes into play with types of technologies such as lasers, microprocessors and other electronic components that work at extremely fast speeds. Nuclear physics research also includes measurements that are close to the extent of picoseconds, as well as the related depiction of nuclear medicine using positron emission tomography (PET). The home computer with a microprocessor, which runs in three Gigahertz, carries out three billion cycles per second. This means that in fact it takes about 330 picoseconds to perform a single binary operation. One of the fastest supercomputers in the US can perform 360 trillion operations per second, a little faster than one operation on Picosecond. China revealed a SuperComputer in 2010, which was able to perform 2.5 Petaflops per second, or 2.5 quadrillion operations every second, which means that each picosecond optimally performs 2,500 calculations.

Lasers intended for operation in the picosecond range radiate light pulses each up to several dozen picoseconds in time. There are several types of laser structures that can work at these speeds, including mass lasers of solid states, lasers thought -out and lasers with q. Range of 100s Picosecond.

Although such ultra -fast lasers are difficult to imagine, there is an even faster level of models. The picosecond pulse laser is 1,000 times slower than the femtosecond laser. As a result, picosecond designs are at least the tip and significantly more economical for use, such as micro-maxing components. Both types of lasers have similar levels of performance for the tasks with which they are entrusted.

in the Nuclear Medicine field, sThree PET creates an image through gamma beams that interact with scintillation crystals to produce Compton electrons at optimal speeds of approximately 170 picoseconds. In fact, it is usually much slower and lasts about 1 to 2 nanoseconds in length on the emission particle. Flight Pet (Tofpet) tries to shorten the real flight under 300 picoseconds, through improvement of photodettectors, scintillation crystals themselves and related electronics. Although these speeds are already incredibly fast, the reconstruction of the image of the human body areas from these emissions is a slow, time -consuming process that often lasts for several days.
