□ ROHS compatible

Measurement Modes

■ LED/LD modulation modes

□ Sinusoidal modulation for single camera applications

□ Selectable modulation frequencies 0.625 ... 20MHz resulting in

unambiguity distance of 7.5m … 240m

■ Distance measurement modes

□ 128 fps 3D TOF with 4x DCS frames, full pixel-field

□ 256 fps 3D TOF with 2x DCS frames, full pixel-field

□ 512 fps 3D TOF with rolling read-out 4x DCS frames, full pix-

el-field

□ SHUTTER release input for precise start/stop and single/con-

tinuous measurement control

■ Non distance measurement modes

□ Ambient-light measurement (Grayscale image without illumina-

tion)

□ Grayscale image with active illumination
