Abstract
A measurement device with front lit (FL) architecture includes a sensor, a mirror-angle to light converter (ALC) and a receiver. The sensor can be configured to convert a physical signal into a sensor output signal. The ALC can be configured to control a mirror angle of at least one mirror within the ALC according to the sensor output signal, in order to redirect a light beam from the FL architecture with the at least one mirror, wherein the FL architecture is integrated into the ALC. The receiver can be configured to receive the redirected light beam as a light spot on a detection area of the receiver, wherein a displacement of the light spot is used as a measurement result for indicating a magnitude of the physical signal.
