STATEMENT OF WORK

FOR

SINGLE PHOTON AVALANCHE DIODE (SPAD) CAMERA

Rev. 30 Jan 2025

I. Background:

A time-correlated single-photon counting camera is required to fill a critical education gap for AFIT remote sensing students. This system is capable of collecting single photon time gated images that allow for 3-D reconstruction of targets at large ranges and through non-deal conditions such as fog are underwater. This system represents a cutting-edge capability that is growing rapidly in the remote sensing community. AFIT currently owns numerous advanced remote sensing systems but none with these specific capabilities. The procurement this system will allow AFIT students to develop expertise in a cutting-edge remote sensing modality which will allow them to better understand the capabilities and limitations of these systems. It will also provide them with a robust understanding of state-of-the-art imaging technologies so that they are better prepared for acquiring these systems for real world operational requirements. This system would be used to support educational requirements in PHYS-542, OENG-780, OENG-651, OENG-650, OENG-533, OENG-530, OENG-647, OENG 616L, PHY521, METG- 644, PHYS-799, and PHYS-999.

II. Technical Requirements:

The following specification lists the minimum requirements for the procurement of a single photon available diode (SPAD) camera.

A single photon avalanche diode (SPAD) array camera is required for active imaging applications in a low photon flux environment.

The SPAD camera should have two modes - photon counting and time-correlated single-photon counting (TCSPC).

Timing information should be provided for each detected photon (per pixel, per frame), with the SPAD camera having direct device integration of timing functionality and readout circuity.

The SPAD camera should be capable of time-stamping each detected photon with a time resolution of less than 60 picoseconds per pixel per frame and then transfer these to the host PC.

The spatial resolution of the detector or the number of pixels/SPADs in the array of the SPAD camera should be 32x32 (1024 pixels).

Spectral region of operation: 390nm to 910nm.

User selectable features allowing built-in raw data processing and frame transfer speeds from 150,000 to 700,000 frames per second.

Custom firmware for in-camera data analysis.

Additional Firmware-accelerated Histogram feature to be included. Proven experience of manufacturer in the SPAD camera sales.

XY Scanner Synchronisation Firmware Addon.

Camera Lens equal to Model # SL-183M

2.1 Essential specifications:

Array size: 32 × 32 pixels.

Each pixel has its own counting and TCSPC-timing electronics (>1000 time bins).

Photon detection efficiency (PDE) at 500nm, peak 28%.

Optical fill factor: 1.5% without microlenses, >15% with microlenses.

After pulsing <0.02%.

TTL or NIM Input and Output for timing synchronisation.

Timing jitter <200ps at FWHM.

Dark count rate <100 Hz for more than 80% of pixels.

Photon counting mode data: 7 bit in-pixel and 16 bit in firmware.

Time correlated mode operation with temporal range 55ps to 57ns and temporal bin of 55 ps.

TDC resolution: 10 bit.

Interframe dead time : < 50ns.

Application Programming Interface for C, C++, Matlab,and Python.

Data output: via USBC at USB 3.1 speed or faster.

Original Manufacturer warranty of 1 year

III. Delivery: The vendor shall deliver and complete all requirements of this Statement of Work no later than 6 weeks after contract award.

Contractor shall be responsible for transportation of all new products, loading, unloading, storage and all necessary movement from factory to final onsite set up.

The contractor Project Manager shall be responsible for on-site coordination of all deliveries of their product, to include access to and operation of any equipment needed for unloading and movement of materials or product necessary to complete all requirements of this Statement of Work.

Free from defects in material and workmanship, under normal and proper use in accordance with equipment user manual, for the period of one year after receipt.

3.1 Delivery Address:

Air Force Institute of Technology (AFIT/ENP) 2950 Hobson Way, Building, #640 Room #265 Wright-Patterson AFB, OH 45433-7765

IV. Invoice and Payment:

The contractor shall be paid upon submission of a properly prepared invoice and after final inspection and acceptance has been made. A proper invoice shall cite the contractor’s name and address, invoice number, invoice date, order number, contract line-item number (CLIN), description of the supplies or service, unit of issue, unit price and extended price, terms of any prompt payment discount offered, and who to notify in the event that the invoice is defective.

The Invoice Shall be submitted to the Wide Area Workflow (WAWF https://wawf.eb.mil/) in accordance with the terms of the final contract award 100% payment upon completion of all requirements specified in the Statement of Work.

V. Delivery Procedures – Commercial Vehicles:

a. The company shall properly ship the system to the Air Force Institute of Technology at WPAFB, OH. All shipping costs to include insurance will be included in contractor’s proposal. Great care using standard, approved packaging methods shall be taken.

b. All vehicles larger than a large pick-up truck are required to be inspected by the Wright- Patterson Air Force Base Commercial Vehicle Delivery Gate (CVDG) prior to entering the installation. Vehicles to be inspected include, but are not limited to, the following:

1. Step van/panel truck

2. Tractor/trailer, box and flatbed containing cargo

3. Tanker trucks

4. Box trucks

5. Tour buses

6. Garbage/recycled waste trucks

7. Concrete trucks/mixers, dump trucks

8. Cranes, recreational vehicles, petroleum tanker

This inspection will be conducted at Gate 26A located off State Route 235.

c. The following are exemptions to vehicles utilizing the CVDG:

1. If the vehicle has the product inside (concrete and asphalt trucks) and timely delivery is necessary due to product deterioration it does not need to enter the CVDG. To bypass the CVDG, the contractor shall submit a list containing drivers’ names, social security numbers and the state in which the driver's license is held for those drivers who will be entering the base. This shall be accomplished 24 hours prior to requested entry time. If entry is requested on Monday, this list must be submitted by Friday at 1630 hours. All lists shall be submitted to the 88th ABW/CE Directorate contract inspector. The only gates that may be used under this exemption shall be 15A, 26A, 38A, and gate 1B. If the driver's name is not on the list, he/she will not be allowed access to the installation through these gates and the base will not assume liability for denied access.

2. If a delivery vehicle must exit, and then re-enter the base to complete its route, the vehicle shall be resealed upon exiting the base. After initially passing through the commercial vehicle delivery gate, trucks shall be resealed at Gates 15A, 38A and 22B. The resealing of the trucks will allow them to continue to any other area of the installation (Areas A, B, or Kittyhawk) without reprocessing through the CVDG. To receive resealing assistance, the drivers shall physically stop at one of the three authorized gates and request the installation entry controller to reseal their truck and provide the next location of their delivery. The controller will reseal the truck and give the delivery driver a pre-clearance form. The driver shall present the pre-clearance form to the entry controller at the next point of installation entry. This reentry can be through any base gate.

d. Vehicles may be subject to an inspection at any of installation entry control points during a directed random antiterrorism measure (RAM.) Any commercial vehicle, regardless of size, can be directed to the CVDG at the discretion of the installation entry controller.
