The sensor has a surface area of 27.7 mm².
There are approx. 12,000,000 photosites (pixels) on this area.
Pixel pitch, which is a measure of the distance between pixels, is 1.52 µm.
Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.
Pixel or photosite area is 2.31 µm². The larger the photosite, the more light it can capture and the more information can be recorded. Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. AgfaPhoto Optima 102 has a pixel density of 43.17 MP/cm². These numbers are important in terms of assessing the overall quality of a digital camera. Generally, the bigger the sensor, pixel pitch and photosite area, and the smaller the pixel density, the better the camera.

Diagonal
The diagonal of AgfaPhoto Optima 102 image
sensor is not 1/2.33 inch as you might expect, but approximately two thirds of
that value  0.3 inch. If you want to know why, see
sensor sizes.
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
Diagonal is calculated by the use of Pythagorean theorem:
Diagonal = √  w² + h² 
AgfaPhoto Optima 102 diagonal
w = 6.08 mm
h = 4.56 mm
h = 4.56 mm
Diagonal = √  6.08² + 4.56²  = 7.60 mm 
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
Width = 6.08 mm
Height = 4.56 mm
Surface area = 6.08 × 4.56 = 27.72 mm²
Width = 6.08 mm
Height = 4.56 mm
Surface area = 6.08 × 4.56 = 27.72 mm²
Pixel pitch
Pixel pitch is the distance from the center of one pixel to the center of the
next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =  sensor width in mm  × 1000 
sensor resolution width in pixels 
AgfaPhoto Optima 102 pixel pitch
Sensor width = 6.08 mm
Sensor resolution width = 3995 pixels
Sensor resolution width = 3995 pixels
Pixel pitch =  6.08  × 1000  = 1.52 µm 
3995 
Pixel area
The area of one pixel can be calculated by simply squaring the pixel pitch:
You could also divide sensor surface area with effective megapixels:
Pixel area = pixel pitch²
You could also divide sensor surface area with effective megapixels:
Pixel area =  sensor surface area in mm² 
effective megapixels 
AgfaPhoto Optima 102 pixel area
Pixel pitch = 1.52 µm
Pixel area = 1.52² = 2.31 µm²
Pixel area = 1.52² = 2.31 µm²
Pixel density
Pixel density can be calculated with the following formula:
You could also use this formula:
Pixel density = (  sensor resolution width in pixels  )² / 1000000 
sensor width in cm 
You could also use this formula:
Pixel density =  effective megapixels × 1000000  / 10000 
sensor surface area in mm² 
AgfaPhoto Optima 102 pixel density
Sensor resolution width = 3995 pixels
Sensor width = 0.608 cm
Pixel density = (3995 / 0.608)² / 1000000 = 43.17 MP/cm²
Sensor width = 0.608 cm
Pixel density = (3995 / 0.608)² / 1000000 = 43.17 MP/cm²
Sensor resolution
Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher
than maximum (not interpolated) image resolution which is usually stated on camera specifications.
Sensor resolution is used in pixel pitch, pixel area, and pixel density formula.
For sake of simplicity, we're going to calculate it in 3 stages.
1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always. 22.8 × 15.5 sensor for example has a ratio of 1.47.
2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
3. To get sensor resolution we then multiply X with the corresponding ratio:
Resolution horizontal: X × r
Resolution vertical: X

(X × r) × X = effective megapixels × 1000000 → 

Resolution horizontal: X × r
Resolution vertical: X
AgfaPhoto Optima 102 sensor resolution
Sensor width = 6.08 mm
Sensor height = 4.56 mm
Effective megapixels = 12.00
Resolution horizontal: X × r = 3004 × 1.33 = 3995
Resolution vertical: X = 3004
Sensor resolution = 3995 x 3004
Sensor height = 4.56 mm
Effective megapixels = 12.00
r = 6.08/4.56 = 1.33 

Resolution vertical: X = 3004
Sensor resolution = 3995 x 3004
Crop factor
Crop factor or focal length multiplier is calculated by dividing the diagonal
of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =  43.27 mm 
sensor diagonal in mm 
AgfaPhoto Optima 102 crop factor
Sensor diagonal in mm = 7.60 mm
Crop factor =  43.27  = 5.69 
7.60 
35 mm equivalent aperture
Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture
with crop factor (a.k.a. focal length multiplier).
AgfaPhoto Optima 102 equivalent aperture
Crop factor = 5.69
Aperture = f3  f5.6
35mm equivalent aperture = (f3  f5.6) × 5.69 = f17.1  f31.9
Aperture = f3  f5.6
35mm equivalent aperture = (f3  f5.6) × 5.69 = f17.1  f31.9
