Hamamatsu Introduces CMOS Image Sensors For Real-Time Distance Measurements

Hamamatsu has introduced new CMOS distance image sensors that offer high-precision, real-time distance measurements using a time-of-flight (TOF) method. Capable of measuring distances of several meters in real time, the sensors are suitable for use in various applications. These include obstacle detection and shape and gesture recognition for robots, collision avoidance for vehicles, as well as intruder detection in security applications.

The CMOS distance image sensors have a spectral response range from 400 nm to 1100 nm, with peak sensitivity in the 800 nm region. This sensitivity matches them well with pulsed light sources such as LEDs and laser diodes used in TOF distance measurements.In addition, they drive the light sources and have a built-in timing generator for easy operation.

Three distance image sensors are available. The S11961-01CR is a 256-pixel linear array with each pixel measuring 20 x 50 μm. The S11962-01CR has a 64 x 64 pixel array and pixel size of 40 x 40 μm. The S11963-01CR features 160 x 120 pixels, each pixel measuring 30 x 30 μm. An additional feature of the S11961-01CR and S11963-01CR is a background subtraction capability that further eliminates background and stray light. Evaluation boards for these sensors are available, but users must supply the light source and optics appropriate for their application.
