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.

Physical Dimensions
The DVXplorer Micro camera is housed in a POM plastic case. The case dimensions are depicted below.
Connectors
DVXplorer Micro has one connector on the back. A USB 3.1 Type-C connector for data and power.
USB C Connector
The USB C connector is used for data and power. Any USB 3.0 or USB 2.0 cable with Type-C 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.
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 640 x 480 and measures:
Width: 640 pixels x 9.0 µm/pixel = 5.76 mm
Height: 480 pixels x 9.0 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.
