In this talk, I will review the evolution of solid-state photon counting sensors from avalanche photodiodes (APDs) to silicon photomultipliers (SiPMs) to single-photon avalanche diodes (SPADs). The impact of these sensors on LiDAR has been remarkable, however, more innovations are to come with the continuous advance of integrated SPADs and the introduction of powerful computational imaging...
We present results from NIRCA – the near infrared readout controller ASIC for high-performance infrared image sensors, and we describe possible use with readout integrated circuits and microbolometer arrays. NIRCA features 16 analog inputs with programmable gain amplifiers, 16-bit/12MSPS analog-to-digital converters and high-speed serial outputs. We measured the performance in terms of...
Radiation in space is a potential risk to human health and electronic systems. Spacepix-3, the successor of Spacepix-2 [1], is a high voltage monolithic active pixel sensor (HV-MAPS) ASIC capable of measuring flux and distinguishing between types of radiation, protons, electrons, and ions. SpacePix3, improved version of the former SpacePix2, features a 64 × 64 pixel matrix with a pixel pitch...
Medipix4 is a hybrid pixel detector readout chip for single photon X-ray imaging, with 320 x 320 pixel array, each pixel being 75 µm x 75 µm in size. The chip operates in two modes: Fine Pitch Mode with a 75 µm sensor pixel pitch and two threshold bins per pixel, and Spectroscopic Mode with a 150 µm sensor pitch and up to eight energy threshold bins. The chip can be fully tiled in both x and y...
DECTRIS Ltd. was founded as a spin-off of Paul Scherrer Institut in 2006. At this time synchrotron and laboratory X-ray science were severely detector limited. The noise-free, high frame and count-rate performance of Hybrid Photon Counting (HPC) detectors not only overcame these limitations but has transformed X-ray science. In combination with an ever-increasing source brightness, improved...
The ePixUHR-35kHz is a novel Application Specific Integrated Circuit (ASIC) developed at the SLAC National Accelerator Laboratory to meet the demanding requirements of the Linac Coherent Light Source II (LCLS-II) X-ray laser facility. The ASIC consists of an array of pixels with a pitch of 100 µm, organized into clusters of 72 pixels each. Each cluster includes a Successive Approximation...
MÖNCH is a hybrid pixel detector featuring 25 μm pixel pitch and analogue readout for X-ray imaging at synchrotron radiation (SR) facilities. Sub-pixel spatial resolution has been demonstrated using charge sharing and interpolation algorithms [1]. The current prototype version, MÖNCH0.4, features 19 different pixel architectures to assess the design choices and components for an optimised...
Two key emerging trends in sensors and detectors are: (1) the application of machine learning (ML) to data processing and (2) the migration of processing from the back-end towards the front-end. Embedded processing allows to reduce the amount of data transmitted (both in terms of data rate and interconnection lines), with evident advantages also in the field of high-count-rate, densely...
