An access control system (ACS) and method controls access to a secure asset. The ACS includes a light emitting unit configured to emit light, an electronically addressable element configured to be electronically switched between a first optical state and a second optical state, an optical sensor configured to sense light, and a controller. The controller is configured to cause the electronically addressable element to switch between a first optical state, which produces non-patterned light at an illumination target, and a second optical state, which produces patterned light at the illumination target, receive, from the optical sensor, data indicative of light reflected from a presentation illuminated at the illumination target, and determine access to a secure asset based on the data indicative of light reflected from the presentation.
An access control system (ACS) configured to control access to a secure asset, comprising:
A non-transitory computer readable medium comprising instructions which, when implemented by a processor, cause the processor to perform operations comprising:
A controller-implemented method of controlling access to a secure asset, the method comprising:
