LADAR and LIDAR Detector Systems

APD and LADAR Detector Arrays

• Sensitivity from below 950 nm out to 1700 nm
• Back-illuminated mesa architecture allows for fast optical overload recovery
• Available for all of Voxtel’s APD families (BSI Deschutes, Siletz, and Siletz-UHG)
• High uniformity of breakdown voltage
• Low pixel defect counts
• Array sizes from 2×2 up to 640×480
• Pixel sizes ranging from 10×10 µm2 to 1×1 mm2
• Radiation-tolerant designs

APDs and LADAR ROICs

Voxtel has broad experience in optical receiver and focal plane array circuit design, which we bring to bear to solve our customers’ difficult problems. A majority of our readout integrated circuits (ROICs) are fabricated using domestic (United States) trusted foundry sources. Many designs include features for increased radiation tolerance and reduced power consumption.

• MHz- to multi-GHz-response amplifiers, allowing nanosecond laser pulse response
• Pixel sizes ranging from 10×10 to 100×100 µm2
• Frame rates up to tens of kHz
• Designs for either integrated-signal wavefront/range-gated imaging or sub-nanosecond pulse detection
• Pulse detection circuits with <250 ps time of flight (TOF) record
• Multiple records per frame: e.g. sampling of three or more pulse amplitude and TOF pairs (first, peak, and last, or first and last three, etc.)
• Radiation-hardened designs
