Article on Hamamatsu ToF Imager

Photonics-Spectra publishes an article "PMD Camera Enhances 3-D Imaging" by John Gilmore (Hamamatsu) and Slawomir Piatek (NJIT). The article talks about Hamamatsu S11963-01CR 160x120 ToF sensor operation and performance:

Indirect ToF principle

The accuracy of the camera using 10-μs pulses (3000 pulses per frame) from an 8 × 8 array of LEDs (λ = 870 nm, full width half maximum = 45 nm), IR-transmission filter HOYA IR83N, f/1.2 lens (focal length 8 mm), and a 160 × 120-pixel Hamamatsu S11963-01CR sensor (pixel size 30 × 30 μm, field of view = 37.5° × 27.7°) is graphed below:
