UCLA Miniscope v4

These are the devices available on the UCLA Miniscope v4:

• UCLA Miniscope v4 Camera System camera sensor:
  • 0.48 Megapixel CMOS 8-bit or 10-bit image sensor (608 x 608 pixels) data
  • Python480 sensor for dynamic adjustment of frame rate in discrete increments: 10, 15, 20, 25 or 30 fps
  • Python480 sensor for dynamic adjustment of exposure in three discrete levels
  • ETL for dynamic and continuous ~500 µm adjustment of imaging depth with off-the-shelf lens configuration
  • LED driver for dynamic and continuous adjustment of excitation light intensity
• Bno055: 9-axis IMU for real-time, 3D orientation tracking updated at the same frame rate as the camera

Tip

Visit the UCLA Miniscope v4 Hardware Guide to learn more about the hardware such as weight, dimensions, and proper power voltages.

The example workflow below can by copy/pasted into the Bonsai editor using the clipboard icon in the top right. This workflow:

• Captures image data from the UCLA Miniscope v4 Camera System and saves it to disk.
• Captures orientation data from the Bno055 IMU and saves it to disk.
• Monitors the UCLA Miniscope v4 port status.
• Automatically commutates the tether if there is a proper commutator connection.

The following pages in the UCLA Miniscope v4 Guide provide a breakdown of the above example workflow.
