Special Issue Information

Dear Colleagues,

Light detection and ranging (LiDAR) sensors have attracted significant research interests for various applications, incuding advanced driver assistance systems (ADAS), autonomous vehicles, robots, drones, mobile phones, elder-care systems, etc. In particular, cost-effective and compact LiDAR can become crucial for the development of short-range home monitoring sensors in the urgently demanding applications of elder-care systems. Yet, current LiDAR sensors require a mechanical scanning system, and thus can hardly satisfy their stringent requirements. Hence, solid-state LiDAR sensors based upon semiconductors have recently been paid a great deal of attention as a key solution.

Single-photon avalanche diodes (SPADs), silicon photomultipliers (SiPMs), and avalanche photodiodes (APDs) especially based on standard CMOS technologies are considered the most crucial devices for solid-state LiDAR sensors because they can not only detect very low-intensity signals, but also provide cost-effectiveness and high-volume manufacturing as CMOS is a universal platform. Recent advances in the fields of CMOS-based SPADs/SiPMs/APDs can certainly facilitate to realize and develop cost-effective and compact solid-state LiDAR sensors.

The goal of this Special Issue is to invite to the submission of high-quality, state-of-the-art research articles that deal with challenging issues in home-monitoring LiDAR sensors. We solicit original papers of unpublished and completed research that are not currently under review elsewhere. Topics of interest include, but are not limited to:

  • Single-photon avalanche photodiodes (SPADs) in CMOS technologies;
  • III-V SPADs for solid-state LiDAR sensors;
  • Silicon photomultipliers (SiPMs);
  • Avalanche photodiodes (APDs);
  • Simulation and modeling of SPADs/SiPMs/APDs;
  • Analog front-end (AFE) circuits for LiDAR sensors;
  • Readout integrated circuit (ROIC) for LiDAR sensors;
  • Solid-state LiDAR systems;
  • Short-range home-monitoring LiDAR

This paper introduces an indoor-monitoring LiDAR sensor for patients with Alzheimer disease residing in long-term care facilities (LTCFs), and this sensor exploits an optoelectronic analog front-end (AFE) to detect light signals from targets by utilizing on-chip avalanche photodiodes (APDs) realized in a 180 nm CMOS process and a neural processing unit (NPU) used for motion detection and decisions, especially for incidents of falls occurring in LTCFs. The AFE consists of an on-chip CMOS P+/N-well APD, a linear-mode transimpedance amplifier, a post-amplifier, and a time-to-digital converter, whereas the NPU exploits network sparsity and approximate processing elements for low-power operation. This work provides a potential solution of low-cost, low-power, indoor-monitoring LiDAR sensors for patients with Alzheimer disease in LTCFs. Full article
