Abstract

An indicia decoding device can have an image sensor and a laser diode assembly configured to project laser light onto a substrate. When a trigger signal is received by the indicia decoding device, the device can calculate a delay and enable the laser diode assembly if a delay threshold is satisfied. The indicia decoding device, in one embodiment, can include a hand held housing and an imaging module carrying the image sensor.
