iPMSEL array on a fingertip; and impressions of light sources DOE, VCSEL, and iPMSEL.
Left: The iPMSEL array consists of 16 iPMSEL elements, each a square of approximately 200 μm and formed at high density on a tiny 2 mm square chip. The iPMSEL array emits light beams while switching their beam patterns by electrical control of each individual element. Right: Concept image of a beam pattern light source (above) consisting of VCSEL, DOE and iPMSEL element (below).
