We compare the perfurlrialice of the cliargecoupled device (CCD) and lateral-effect pliotocliode (LEP) as active rangefinder iriiage seiisors m i d discuss the benefits arid drawbacks of different optical !sniirces (lasers arid LEDs). We predict the pcrfnrinance of a large depth of field laser/LEP seiisor arid coinpare real results with theoretical prediction.
