Pulsar: Photomodules on a chip

2023: Product Announcement

At the end of September 2023, it became known about the creation of the first Russian photomodules on a chip. We are talking about the development of NPP Pulsar (part of Roselectronics, which in turn is part of Rostec).

According to the press service of Rostec, matrix photomodules based on silicon crystals "see" objects at any time of the day and are capable of forming both black and white and color images. The novelty, completely created from Russian components, can be used as part of video monitoring, scanning systems, as well as for aiming high-precision weapons.

Photomodule on chip

Each module is a crystal on which an array of photosensitive elements is mounted, a 10-bit analog-to-digital converter and a signal generator controlled by a data transmission interface (SPI). To obtain a color image, an RGB Bayer filter is applied to the surface of the matrix. The device generates a picture with a resolution of 1280x1024 pixels, which allows you to display details with high definition.

The new Russian modules are characterized by low power consumption of 60 mV and "see" in the range of 400-900 nm, which allows you to use these photodetectors to obtain a high-quality image at any time of the day.

Photomodules are created using the technology of complementary metal-oxide-semiconductor structure. This is the most common current technology for building integrated circuits using field effect transistors with isolated gate and different conductivity channels. A distinctive feature of such schemes is extremely low power consumption in static mode and high speed.

By the end of 2023, NPP Pulsar plans to present a miniature camera for technical vision based on these modules.^[1]
