Merlin 32x32 free-running LiDAR camera

The Princeton Lightwave asynchronous 32 x 32 Geiger-mode avalanche photodiode (GmAPD)
camera is a turn-key system containing a single-photon imaging sensor in which every pixel provides time-of-flight information with free-running operation and fully asynchronous timestamp readout. The camera can collect sub-nanosecond resolution timestamps for arbitrarily long periods of time as well as emulate gated (framed) operation, and the sensor can generate timestamps at rates of nearly 1 Gsamples/second. The sensor engine of the camera is a focal plane array (FPA) with hexagonal geometry pixels on a 65.8 μm pixel pitch formatted in a rectangular imaging area of 2.1 mm x 1.8 mm. The FPA is assembled by flip-chip bonding an InP/InGaAsP GmAPD detector array to a custom CMOS readout integrated circuit (ROIC) and then attaching a GaP microlens array to the GmAPD array to provide a high optical fill factor. The hermetically sealed FPA housing has an integrated two-stage thermoelectric cooler to maintain appropriate operating temperature with closed-loop feedback adjustment. The GmAPD camera is supplied as a fully integrated system controlled by a high-performance personal computer with on-board SSD storage and GUI-driven control software.

GmAPD pixels provide true single-photon sensitivity, with asynchronous cameras available in two
wavelength ranges. The 1.06 μm camera is sensitive in the wavelength range from 1020 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 1620 nm, covering eye-safe illumination beyond 1400 nm.

Kestrel 32x32 flash 3D LiDAR camera

The Kestrel product family includes the most temporally precise cameras for low light level detection in the near infrared.  It has a focal plane array of 32 x 32 pixels, with each pixel capable of detecting a single photon with 250 ps timing resolution.  The Kestrel is typically used for collecting returns from the flash of a nanosecond-scale laser pulse in 3D LIDAR applications, providing time-of-flight resolution of 3.75 cm. The Kestrel’s in-pixel counters with 8,000 time bins enable each pixel to count for a duration of 2 µs, providing measurements over a range depth of 300 meters. The camera’s counting duration can be extended to 10 µs, increasing the range depth capability to 1,500 meters, with a proportional trade-off in time-of-flight resolution to 1.25 ns, or 18.75 cm.  The Kestrel performs framed readouts up to 186,000 times a second, enabling the collection and recording of up to 200 million pixel measurements per second.  The camera dimensions are 10 cm x 10 cm x 9 cm, it weighs 1.4 kg, and its maximum dissipation is 16 W. The Kestrel camera family covers the spectral range from 1.0 µm to 1.6 µm, with cameras optimized for use with lasers at 1.06 µm or 1.55 µm

Falcon 128x32 flash 3D LiDAR camera

The Falcon product family provides the most versatile imaging capability for low light levels in the near infrared.  It has a focal plane array of 128 x 32 pixels, with each pixel capable of detecting a single photon with 500 ps timing resolution.  The Falcon is typically used for collecting the returns from the flash of a nanosecond-scale laser pulse in 3D LIDAR applications, providing time-of-flight resolution of 7.5 cm. The Falcon’s in-pixel counters with 8,000 time bins enable each pixel to count for a duration of 4 µs, providing measurements over a range depth of 600 meters. The camera’s counting duration can also be extended to 40 µs, increasing the range depth to 6,000 meters, while proportionately trading off time-of-flight resolution to 5 ns, or 75 cm.  The Falcon performs framed readouts up to 110,000 times a second, enabling the collection and recording of up to 400 million pixel measurements per second.  The camera dimensions are 10 cm x 10 cm x 9 cm, it weighs 1.4 kg , and its maximum dissipation is 20 W. The Falcon camera family covers the spectral range from 1.0 µm to 1.6 µm, with cameras optimized for use with lasers at 1.06 µm or 1.55 µm.
