Abstract: A chopped PIR (C-PIR) sensor is capable of detecting both stationary and moving objects with a high degree of accuracy using a narrow infrared semi-transparent chopper to temporally shutter incident radiation received by pyroelectric sensing elements. Demonstrating a field of view of 110° (horizontal) and 90° (vertical), the C-PIR sensor can detect stationary objects located within 4 m of the sensor, and moving objects located within 8 m of the sensor with 100% accuracy.

Abstract: A package assembly includes a circuit substrate, a top-emitting (TE) vertical cavity surface emitting laser (VCSEL) die having a two-dimensional (2D) matrix addressable emitter array, and a driver integrated circuit (IC) having a flip-chip interconnect configuration. The TE-VCSEL die and the driver IC are coupled together to form a die stack that is mounted to the circuit substrate, with the TE-VCSEL die arranged between the driver IC and the circuit substrate. TE-VCSEL die comprises an optical output arranged at a main surface coupled to the driver IC. The optical output is configured to output light generated by one or more emitters of the emitter array. Thus, the TE-VCSEL die is configured to emit light away from the circuit substrate.

A direction of the second angle with respect to a surface of the VCSEL array may be opposite to a direction of the first angle with respect to the surface of the VCSEL array.
