Optical dating recuperation after bleaching

These traps are steadily refilled after sediment deposition and the longer the grains remain buried, the more TL they will emit when measured.

In 1985, Huntley and colleagues proposed ‘optical dating’ as a simpler and superior means of stimulating the light-sensitive traps in Quaternary sediments, and this is now the principal luminescence-based method of dating geological and archaeological deposits.

Attention was turning from the use of thermoluminescence (TL) dating to estimate the time of last heating of archaeological objects, such as pottery and burnt flint, to the TL dating of unheated sediments that had been transported by wind and then deposited on the landscape.

Kód VIN lze vyčíst přímo v dokumentech vozidla (velký a malý technický průkaz, doklad o STK, zelená karta). Je zpravidla vytištěn na štítku nebo vyražené přímo do karosérie vozu.

VIN kód lze nalézt na několika místech v autě, liší se podle značky vozu (viz horní obrázek): Získaný kód je 17-místný a musí přesně shodovat s údaji na dokladech a na voze.

For the calculation of the Lx/Tx value the function Calc_OSLLx Tx Ratio is used.
