1 General Description

Mira220 is a 2.2 MP NIR enhanced global shutter image sensor with a small 2.79 μm pixel size. It has excellent low light sensitivity made possible by a state-of-the-art stacked BSI technology. With an effective resolution of 1600 × 1400 and a maximum bit depth of 12 bits, the sensor supports on-chip operations like external triggering, windowing, horizontal or vertical mirroring. The maximum frame rate is 90 fps at full resolution and bit depth. The sensor has a MIPI CSI-2 interface to allow easy interfacing with a plethora of processors and FPGAs. On-chip registers can be accessed via the standard I²C interface for easy configuration of the sensor. Due to its small size, configurability and high sensitivity both in visual as well as NIR, the Mira220 is well suited for 2D and 3D applications, which include Active Stereo Vision, Structured Light Vision for Robotics and AR/VR. High sensitivity in NIR enables increased measurement range and allows overall system power consumption optimization which is key for battery powered consumer and industrial applications.

2 Typical Operating Characteristics

2.1 Electro-Optical Characteristics

Below are the typical electro-optical specifications of Mira220. Figure 3: Optical Features of Mira220 Parameter Value Remark Active Pixels 1600 (H) × 1400 (V) Pixel Pitch 2.79 × 2.79 µm² Optical Format 1/2.7” Pixel Type BSI global shutter With fixed pattern noise correction and reset (kTC) noise canceling by correlated double sampling (CDS) coupled with high sensitivity. Shutter Type Pipelined global shutter Exposure of next image during readout of the previous image. Figure 4: Typical Electro-Optical Characteristics Parameter Value Remark Supported Lens Chief Ray Angles (CRA) 0° to 30° Extra wide acceptance angle of the Mira220 pixel means any lens profile with these CRA values would provide decent performance.
