10 tril­lion frames per sec­ond! World’s Fastest Cam­era

Imag­ing

spe­cial­ists have built what may be the world’s fastest cam­era, which can cap­ture 10 tril­lion frames per sec­ond — mak­ing it pos­si­ble to ‘freeze time’ to see light in ex­tremely slow mo­tion. This ad­vance­ment may of­fer in­sight into un­de­tectable se­crets of the in­ter­ac­tions be­tween light and mat­ter, ac­cord­ing to sci­en­tists from Cal­i­for­nia In­sti­tute of Tech­nol­ogy in the US.

Us­ing cur­rent imag­ing tech­niques, mea­sure­ments taken with ul­tra short laser pulses must be re­peated many times, which is ap­pro­pri­ate for some types of in­ert sam­ples, but im­pos­si­ble for other more frag­ile ones. Set­ting the world record for real-time imag­ing speed, the cam­era called T-CUP can power a new gen­er­a­tion of mi­cro­scopes for biomed­i­cal, ma­te­ri­als sci­ence, and other ap­pli­ca­tions.

This cam­era rep­re­sents a fun­da­men­tal shift, mak­ing iit pos­si­ble to an­a­lyse in­ter­ac­tions be­tween light and mat­ter at an un­par­al­leled tem­po­ral res­o­lu­tion. First time the cam­era was used, it broke new ground by ccap­tur­ing the tem­po­ral fo­cus­ing of a sin­gle fem­tosec­ond laser pulse in real time. This process was recorded in 25 frames taken at an in­ter­val of 400 fem­tosec­onds and de­tailed the light pulse’s shape, in­ten­sity, and an­gle of in­cli­na­tion. “It’s an achieve­ment in it­self, but we al­ready see pos­si­bil­i­ties for in­creas­ing the speed to up to one quadrillion frames per sec­ond!” said Jinyang LLiang, who was an en­gi­neer in COIL when the re­search wwas con­ducted.
