New 128 x 32 Geiger-mode Avalanche Photodiode (GmAPD) Camera

The Princeton Lightwave 128 x 32 Geiger-mode avalanche photodiode (GmAPD) camera is a turn-key system containing a single-photon imaging sensor designed for three-dimensional laser radar (LADAR) imaging with time-of-flight information
(PresseBox) (Martinsried, ) The GmAPD pixels of this camera provide true single photon sensitivity, with cameras available in two wavelength ranges. The 1.06 µm camera is sensitive in the wavelength range from 920 nm to 1140 nm, including common pulsed laser wavelengths at 1064 nm and 1030 nm. The 1.55 µm camera is sensitive in the wavelength range from 1400 nm to 1610 nm and is ideal for eye-safe illumination sources.

Princeton Lightwave Geiger-mode 3D LIDAR cameras are based on a focal-plane array of Indium Gallium Arsenide single-photon sensitive APDs, attached to a custom CMOS readout designed for high-speed time-of-flight ranging. These sensors are available in formats of 32x32 or 32x128 pixels and are optimized either for 1064nm or 1550nm laser sources. This allows both defense and commercial applications of three-dimensional laser radar systems with time-of-flight information captured at every pixel in the array. The 1550nm camera, with lasers operating at eye-safe wavelength, is particularly adapted to applications in the public space such as autonomous driving and short range mapping. Princeton Lightwave is the leader in Geiger-mode LIDAR imagers in the shortwave infrared.

Applications are 3D mapping, ranging, or autonomous driving; single-photon imagers for free space communications or receivers for quantum cryptography.
