20.500.12556/RUL-100567 Zasnova in izvedba optične tarče Design and implementation of an optical target Cilj magistrske naloge je bil razviti optično občutljivo tarčo za lasersko pištolo za varen strelski trening doma. Na tarčo streljamo z laserskim žarkom, ki je amplitudno moduliran s frekvenco 1 kHz. Laserska svetloba se odbije od difuzno bele tarčne ploščice do štirih simetrično postavljenih fotodiod. Dobljene štiri signale vzorčimo z okoli 40k vzorci na sekundo, se fazno vpnemo na njihovo vsoto, izprojiciramo njihove amplitude in jih preračunamo v položaj laserske pike na tarčni ploščici. Na ta način smo dosegli 1,2 mm ločljivost lege laserske pike. The purpose of the thesis was to develop an optically sensitive target for a laser gun for safe sports shooting training at home. The target is shot at with a laser beam modulated at 1 kHz. The laser light scatters off a diffuse white target disc and arrives at four symmetrically positioned photodiodes. We sample the four signals at 40 kS/s, phase-lock on their sum and calculate their amplitudes. By comparing the amplitudes we determine the position of the laser spot on the target disc. In this way we achieved a 1.2 mm resolution of the laser spot position.
