Claim 11:
12. A method for driving an aiming assembly of a barcode imager, the method comprising:
obtaining, at a controller, an operating mode of the barcode imager having an imager configured to capture plurality of images over a field of view of the barcode imager, each image is to be captured during a frame duration of the barcode imager;
in response to the operating mode, determining, at the controller, a duty cycle of a single aiming pulse per frame duration, the single aiming pulse comprising a green laser aiming pattern generated by a green laser source of the aiming assembly and comprising an emission having a wavelength within 495 nm-570 nm,
wherein determining the duty cycle of the green laser aiming pattern comprises identifying the duty cycle that simultaneously satisfies a frame duration-independent, peak pulse optical power constraint and a frame duration-dependent heat dissipation constraint, and
wherein obtaining the operating mode comprises determining if the barcode imager is in (i) a trigger-level mode in which the imager captures the images in response to actionable trigger or (ii) a presentation mode in which the imager captures images over a continuous time period containing a Plurality of consecutive frame durations, wherein the heat dissipation constraint differs for the trigger-level mode from the heat dissipation constraint for the presentation mode.
