Cut­ting-edge crime scene tech­nol­ogy

Public Sector Manager - - Trailblazer -

The CSIR's new-gen­er­a­tion fin­ger­print­ing sens­ing tech­nol­ogy, launched in 2016, uses high-speed, largevol­ume op­ti­cal co­her­ence to­mog­ra­phy (OCT).

OCT uses light to cap­ture, in 3D, the finest of de­tails from bi­o­log­i­cal tis­sue.

It could be likened to ul­tra­sound, but us­ing light.

The OCT de­vice will con­trib­ute to law en­force­ment and foren­sics.

Crime-scene per­son­nel can use the OCT de­vice to scan ar­eas and lift fin­ger­prints with­out the use of dust­ing and the risk of con­tam­i­na­tion.

The con­tact­less na­ture of the scan means that mul­ti­ple ac­qui­si­tions are pos­si­ble. Since OCT is non­de­struc­tive, sec­ondary analy­ses can be per­formed and used to iden­tify crim­i­nals.

It can also de­tect sweat glands and can also de­tect if the sub­ject be­ing scanned is dead or alive.

These im­por­tant qual­i­ties en­hance bio­met­ric se­cu­rity fea­tures for high-end ap­pli­ca­tions such as mil­i­tary, na­tional se­cu­rity points, and foren­sics.
