1 The temporal resolution is characterized by the timestamp unit. In fact, a timestamp unit of 1 us offers minimum gain over a timestamp unit of 200 us. For more explanation, please refer to our white paper.
2 The temporal latency is given as a nominal number and can be improved with strong lighting or optimised biases.
IMU
6-axis (Gyro + Accelerometer), up to 8 kHz sampling rate. The IMU is synchronized with the event and frame output. Read more in the IMU section.
Camera Synchronization / Trigger Input
Supports multi-camera time synchronization via daisy chain connection and external event injection.

Physical Dimensions
The DVXplorer Lite camera is housed in a POM plastic case. The case dimensions are depicted below.
Connectors
DVXplorer Lite has three connectors on the back. One USB 3.0 Micro B connector for data and power, and two sync connectors for multi-camera synchronization or external trigger input.
USB 3.0 Connector
The USB 3.0 Micro B connector is used for data and power. Any USB 3.0 or USB 2.0 cable with Micro B type connector can be used. However, USB 3.0 speeds are only supported when using a USB 3.0 cable. Usage of cables with appropriate locking screws are recommended for a more secure and robust connection.
Sync Connectors
The synchronization connectors are HiRose HR10A-7R-4P (male, SYNC OUTPUT) and HR10A-7R-4S (female, SYNC INPUT) connectors. Cables should use the matching connectors HR10A-7P-4S (female) and HR10A-7P-4P (male).
Please note that to keep full electrical isolation between different cameras, the cable should not be shielded, or if it is, the shield should not connect one end of the cable to the other.
Input signals can be 3.3V or 5V, depending on the VDD_IN supplied externally, output signals are 5V, as is VDD_OUT. If you chain cameras together for synchronization, the clock and VDD will be 5V, for example.
Synchronization connectors pinout is shown in the image above. Please note that all the pins in the SYNC IN ports are isolated from the SYNC OUT ports.
Optics
The camera lens mount is designed to accommodate CS-mount lenses. Other lenses can be accommodated by using adapters. The standard lens shipped with the camera is a C-mount lens and ships with an adapter. The chip requires a lens designed for 1/2.5” imagers.
The field of view (FOV) depends on the focal length L of the lens and the size W of the pixel array. It is computed from geometrical optics, not accounting for any lens distortion. The angular field of view (AFOV) is given by:
The linear FOV (LFOV) at a distance D from the lens is given by:
The pixel array has a resolution of 320 x 240 and measures:
Width: 320 pixels x 18 µm/pixel = 5.76 mm
Height: 240 pixels x 18 µm/pixel = 4.32 mm
Diagonal: 7.20 mm
Computed Field of View
The following table shows the horizontal and vertical field of view in degrees and its size at various distances for different common focal lengths.
