Angular Response vs. Incident Light Angle 60 Data Sheet ADPD2140 THEORY OF OPERATION ANGULAR RESPONSE The ADPD2140 consists of arrays of silicon p-type, intrinsic, n-type (PIN) photodiodes that provide a linear measurement of incident infrared light angle. There are four separate channels on the ADPD2140, each corresponding to one photodiode. The low junction capacitance and low dark current of the ADPD2140 allows optimal integration with the ADPD1080 photometric front end. This complete solution offers additional ambient light rejection, low power operation, and analog-to-digital conversion of the ADPD2140 analog signals. TYPICAL CONNECTION DIAGRAM VLED1 4.7F TO/FROM HOST PROCESSOR I2 C BUS SDA SCL The resulting quantities (x and y) are ratios related to angles through a constant term, M. Calculate angles in the horizontal and vertical direction by dividing x and y by the constant term, M (see Table 1). Angles measured by the ADPD2140 are linear to 5 within an angular field of view of 35 and zero crossing offset at 5, as seen in Figure 9. The directionality when using Equation 1 and Equation 2 is shown in Figure 10, which indicates positive angles in the x and y directions. x 22 28 POWER-DOWN CONTROL y DVDD AGND 0.1F VREF AVDD 0.1F 0.1F PD1 Figure 10.

With up to eight photodiode input channels, the ADPD1080 is a preferred choice for the analog front end for interfacing with the ADPD2140. In this configuration, the ADPD2140 and ADPD1080 solution can operate using synchronous LED pulses to detect the angle of light reflected from objects or used in ambient measurement mode to provide a measure of the incident angle of an ambient or other unsynchronized light source. For reference, the optimal choice of reverse bias for typical operation with the ADPD2140 is 0.2 V. LGND The ADPD2140 enables a 2-axis light angle measurement, in both the x and y direction. To calculate angles in the x and y direction with respect to the sensor use the four photodiode channels (xL, xR, yT, and yB) and the following equations: ADPD2140 Data Sheet APPLICATIONS INFORMATION 8. GESTURE RECOGNITION The unique angular response of the ADPD2140 coupled with the high performance ambient light rejection of the ADPD1080 enables a robust and effective implementation of gesture recognition. The following algorithm demonstrates recognition of up, down, left, right, and click hand gestures based on data from the four channels of the ADPD2140: 1. 2. 3. 4. 5. 6. 7. Prior to operation of the ADPD2140 and the ADPD1080 for gesture recognition, calibrate the ADPD1080 clocks. See the ADPD1080 data sheet for more information on how to calibrate the 32 kHz and 32 MHz clocks. Set the ADPD1080 mode of operation to sample mode by writing 0x2 to Register 0x10, Bits[1:0]. Collect the data measured by the device. See the ADPD1080 data sheet for instructions on how to read data from registers using the first in, first out (FIFO) and interrupts. Data is available directly from data registers or from the 128-byte FIFO in Register 0x60, Bits [15:0]. The data in the four output channels of the ADPD1080 calculates the angle of incident light. After the xL, xR, yT, and yB data are collected, calculate the angles and intensity with the following equations: Horizontal angle: x = (xL - xR)/(xL + xR) Vertical angle: y = (yT - yB)/(yT + yB) Intensity: L = xL + xR + yT + yB Prior to gesture event detection, offsets of the ADPD1080 must be digitally subtracted from each channel. These offsets are not due to photodiode dark current and are set by the ADPD1080 on-chip analog-to-digital converter (ADC). Register 0x18, Register 0x19, Register 0x1A, and Register 0x1B contain the ADC offsets for Timeslot A, while Register 0x1A, Register 0x1B, Register 0x1E, and Register 0x1F contain the ADC offsets for Timeslot B. The nominal value for all offsets is 0x2000. To modify these offsets, measure the 16-bit output of each channel, in ADC codes, and add it to the existing 16-bit number in the ADC offset register, SLOTx_CHx_OFFSET (nominally 0x2000). Then, write to the ADC offset register with this result. When the offsets are correctly subtracted, the intensity reading L is close to zero codes with no objects in the sensor field of view. The start of a gesture event can be defined as occurring when intensity data crosses a preset threshold. Nominally, this threshold must be set to 1000 codes. However, the threshold can be adjusted to suit the application. The end of a gesture event can then be defined as the number of samples after which the intensity drops back below the preset threshold, past a certain minimum number of samples (nominally five samples). Use the start and stop points of the gesture event to determine whether the gesture was up, right, left, down, or a click. For more detail on this process, see the following pseudocode: event = False intensityThreshold = 1000 (should be adjustable by the user) clickThreshold = 0.07 (should be adjustable by the user) if event = True: i += 1 if i >= 5 and L < intensityThreshold: event = False gestureStopX = x gestureStopY = y m = (gestureStartY - gestureStopY)/(gestureStartX - gestureStopX + 1e-6) d = sqrt((gestureStartX - gestureStopX)^2 + (gestureStartY - gestureStopY)^2) if d < clickThreshold: gesture = `CLICK' else: if abs(m) > 1: if gestureStartY > gestureStopY: gesture = `UP' else: gesture = `DOWN' elif abs(m) < 1: if gestureStartX > gestureStopX: gesture = `LEFT' else: gesture = `RIGHT' else: if L > intensityThreshold: i = 0 event = True gestureStartX = x gestureStartY = y Rev. 0 | Page 8 of 12 Data Sheet ADPD2140 OBJECT TRIANGULATION While a single ADPD2140 allows for measurement of the x and y coordinates of an object or light source, two ADPD2140 placed at a distance apart can calculate the z distance using triangulation. The superscripted A and B refer to ADPD2140 sensors that are measured in Timeslot A and Timeslot B of the ADPD2140. Calculate the triangulation distance z as follows: Figure 12 shows the operation of a typical triangulation measurement using the ADPD2140. OBJECT If sign(yA) = sign(yB), C A z B 2 (y - y ) B Or, if sign(yA) sign(yB), z= A C A ( y + y B )2 EMITTER ADPD2140 ADPD2140 TIMESLOT A C is an empirically determined proportionality constant that depends on the baseline distance between the two angle diodes, which converts the x and y measurements to angles, in radians. For reference, the baseline distance, c, between both angle diodes is equal to 1" on the EVAL-ADPD2140Z evaluation board. This quantity sets the units of the final distance measurement output.
