DATASHEET – epc635
3D TOF Imager 160 x 60 Pixel
General Description
The epc635 is a fully integrated 3D-TOF imager with a resolution of
160 x 60 pixels (Half-QQVGA). As a system on chip, the epc635
contains next to the CCD pixel-field the complete control logic to
operate the device. The output of the chip is 12 bit DCS distance
data per pixel, which are accessible through a high-speed digital 8-
bit parallel video interface.
Only few additional components are needed to generate a com-
plete 3D camera. Depending on illumination power and optical de-
sign, a resolution in the millimeter range for distances up to dozens
of meters is feasible. Up to 512 full frame TOF images are deliv-
ered in rolling mode. The extremely high sensitivity of the chip al-
lows for a reduced illumination power and reduced overall power
consumption compared to other TOF imagers.
epc635 is based on the same technology and instruction set as the
existing epc660 QVGA TOF imager from ESPROS.
An evaluation kit for the epc635 is available with hard- and soft-
ware examples and a comprehensive manual to speed up system
integration.
