5.7

VCSEL

Internal protection ensures no single point of failure will cause the VCSEL to violate the Class

1 Laser Safety.

•

Laser Safety

Class 1

•

VCSEL Pulse Rep Rate

26.6 ns (37.6 MHz)

If VCSEL_clk_div=1, the frequency is divided by two.

Typical optical characteristics

•

VCSEL Field of Illumination (FOI)

25º

Full width from 1% of maximum up to maximum

21º

Full width from 5% of maximum up to maximum

19º

1/e^2

•

TOF Sensor Field of View (FOV)

37º

FWHM

– for short distances

24º

FWHM

– for long distances

The SPAD FoV angular response uses the full TMF8805 SPADs for short distances. The

SPAD FoV is reduced when the TMF8805 operates in long distance since the SPAD array is

reduced. This helps to improve ambient light tolerance1.
