    • Dates: April 2019 - August 2019

    • Task: SPAD receiver consultancy (ideas, design factors, advice and system-level modelling) as to a high readout rate (2ns bins) multi-channel (256) photon counting receiver array for automotive LiDAR.

    • Working with Dr Gleb Alexrod (Lumotive CTO and Co-Founder) [Link]

Sept-2018 to April-2019:

  • Coda Octopus Products Ltd (Sonar - Edinburgh) - SENIOR Electronics / Hardware Engineer

    • Electrical systems design covering:
      - Analogue Filter Design and Test for Military Customers
      - New Product Generation PCB Design (Altium Designer)
      - Algorithm Development and DSP (improved object detection)
      - System-Level and Data Acquisition Architecture and Analysis
      - Feasibility and system level simulation, obsolete part replacement
      - Peer Review for a publication aimed at a SONAR trade-magazine
      - Specifications engineering and robust design documentation
      - Generated proposals for changes to the existing and new designs to aid optimisation and removal of design bottlenecks, e.g. use of managed time-division to reduce cost over a fully-parallel readout scheme.
      - ISO9001 compliance (further reading on DO-256 and ISO-26262)

    • Despite FPGA (Verilog/VHDL), GPU, Microcontroller and Embedded Software being mentioned on the job advert, no tasks utilising these skills were forthcoming simply due to the lack of sufficient work over and above existing FPGA-specific staff. This prompted the move to Leonardo to ensure I kept my existing digital logic specialism progressing.

    • Sole-development of the IC including schematics, layout, padring, configuration SPI and characterisation.

    • Sole-development of a testing harness PCB and FPGA (Verilog) and PC software (Java) to enable tests for thesis and publication. Optical setups were also required to enable various experiments, processed using Matlab.

    • The project initially centred on a human psychometric study (sex, age and geographic regional factors) for the subjective "perfect" image and camera exposure.

    • Matlab algorithm development looking at image statistics including the Kolmogorov measure, entropy and higher central moments to ascertain the shift in exposure value needed to bring a preliminary 'video-feed' capture into a better exposure region.

June-2007 to August-2007:

  • ST Microelectronics (CMOS Image Sensors - Edinburgh) - 3rd to 4th Year UG Summer Placement

    • I worked on image processing algorithms for a blind raw image file parser. Algorithms and GUI to automatically obtain bit depth, width, length, header size, bit-order and colour mode from RAW Bayer images.

    • This was a great introduction to image processing including colour channel correlation for an automatic preview of the RAW image prior to demosaicing.

    • The GUI was programmed using Python and WX Python widgets, while the back end algorithms were initially designed in Python and ported to C for faster computation with SWIG wrappers for easy python module data flow.
